All about VAZ 2114 8 valves. Which VAZ engine is better

The 2111 engine is conventionally considered “native” for the VAZ 2114, since it has been installed for 4 years since the creation of the car model. This version of the internal combustion engine has distributed injection and 4 valves and a volume of 1.5 liters. A tuned version of 21114 with a volume of 1.6 liters was also used by increasing the height of the cylinder block.

In 2007, the engines were “pulled up” structurally to Euro-4 standards, the “four” was equipped with a 1.6 liter modification 11183 with 8 valves, electronic pedal gas and electric throttle, polymer receiver instead of aluminum.

Since 2009, the VAZ 2114 model has been modernized by its subsidiary Super-Avto CJSC. A 16-valve internal combustion engine 21124 with a volume of 1.6 liters and a power of 89 hp began to be used. With. A year later, the power unit was upgraded again; a modification of the 2126 engine of the same volume of 1.6 liters was used, but with a power of 98 hp. With.

Characteristics of motors 2114

Since release Lada Samara VAZ-2114 specifications gasoline drives were constantly improved. From the owners domestic cars In principle, questions about what kind of oil to pour into the engine do not arise, since standard requirements apply for Lada, Lada and Samara - 5W30 or 10W30.

In addition, you should know what kind of oil to use in transmission gears - the instructions from the AvtoVAZ manufacturer recommend using the GL-4 group of lubricants with a viscosity of 80W85 (mineral), 75W90T (synthetic) or 85W90 (semi-synthetic).

After filling with synthetics, the gearbox becomes noisy, the oil is more expensive, but the lubricant is mostly imported, which provides additional guarantees. Domestic manufacturers most often produce semi-synthetics of average quality for engines and transmission gearboxes.

The technical characteristics of the engine are as follows:

For high-quality maintenance of internal combustion engines, the engine manufacturer issues a manual containing a description of the drive parameters, the frequency of replacing consumables and step-by-step repair operations. The same operating manual recommends the volume of oil in the gearboxes in the engine.

Engine design features

Initially, the engine of the VAZ-2114 was 8 valve, had a volume of 1.5 liters, complied with Euro-2 standards, and was marked 2111. In 2005, these engines were boosted:

  • to increase the volume to 1.6 liters, the block is increased in height by 2.3 mm;
  • Several configurations have been created - for Euro-2 version 21114-00, for Euro-3 model 21114-20 and for Euro-4 modification 21114-70;
  • The crankshaft, valve system, camshaft correspond to 11183;
  • The cylinder head received an enlarged combustion chamber of 5 x 8.1 cm, which increased power.

An important feature of the 21114 internal combustion engine is phased rather than pairwise-parallel injection, which was used in the original 2111. It has become more compact attachments:

  • catalytic collector instead of the neutralizer and exhaust pipe;
  • injector ramp instead of the fuel return line.

The modernization also affected other components, for example, a January 7.2 or M7.9.7 controller was used, the ignition module was replaced with a coil with 4 terminals.

At the same time, VAZ-2114 began to be equipped with engines from Kalina 11183, which have some differences from the previous version:

  • the shape of the combustion chamber has been improved;
  • The generator is secured with a bracket, the tensioner is modernized.

In 2008, the 2114 engine received a new M73 ECU, and in 20011, the M74 “brains” to achieve Euro-4 standards. The control became completely electronic, but for another whole year the designers corrected firmware defects until they created its final version I414DE07.

The next engine, 2114, was installed on the car by a subsidiary of the manufacturer AvtoVAZ, called Super-Auto, in 2009. It was the 16 valve engine 21124 of the “tenth” VAZ family with improved characteristics:

  • "high" block of blue color(197.1 mm);
  • injectors pressed into 2–5 main bearing supports, cooling the pistons with oil;
  • the groove depth of the holes in the valves is 5.53 mm, which ensures the safety of the valves in the event of a timing belt break, major renovation not required.

The following year, the fourteenth models began to be equipped with 21126 engines from export Priors. After tuning the engine 21124, internal combustion engine device differs in the following nuances:

  • honed cylinders, gray block;
  • crankshaft pulley and timing belt with semicircular tooth;
  • the weight of the connecting rod and piston group is reduced;
  • there is no friction in the lower head of the connecting rod;
  • candle glasses are built into the head.

The internal combustion engine uses the principle of hydraulic compensation of valve clearances; the 0.45 mm thick cylinder head gasket is made of multilayer metal. The motor is equipped for Euro-3 with a collector 11194-1203008-10 or Euro-4 with a collector 11194-1203008-00. The service life of the pump has been increased due to a new design of the oil seal and bearing, and changes to the toothed pulley.

The ignition system has a separate coil for each spark plug. Phased injection, stainless steel fuel rail, January 7.2 or M7.9.7 controllers.

Cons and pros

Depending on which 2114 engine is used, the owner’s risks differ:

  • 2111, 21183, 21114 and 21124 – do not bend the valve if the timing belt breaks;
  • 21126 – valve bending due to insufficient groove.

The main disadvantage of the latest 16 valve versions is the lighter crank mechanism:

  • the engine is adjusted to Euro-4 standards;
  • to reduce weight, the length of the piston skirt is reduced;
  • Accordingly, the width of the oil scraper and compression rings decreases;
  • The resource of the internal combustion engine is sharply reduced.

For example, in Japan, manufacturers abandoned Euro-4 standards, considering that the reliability and high service life of the motor are more important for the consumer.

The drive power increased from 77 Horse power to 81 hp, then 82 hp, 89 hp, and 98 hp. In models with hydraulic compensators, periodic adjustment of this unit is not required, however, the quality of the oil in the system must be high for normal operation of the pushers.

Maintenance schedule

To avoid having to carry out expensive overhauls of the Lada Samara 2114 yourself, you should follow the manufacturer’s recommendations for servicing the internal combustion engine:

Maintenance objectTime or mileage (whichever comes first)

Typical breakdowns

The very first 1.5 liter engine 2114 has disadvantages:

  • periodic valve adjustment;
  • unreliable injection system;
  • loosening the exhaust manifold nuts;
  • Leaking gaskets of the fuel pump, distribution sensor of the ignition system.

The next 1.6 liter engine does not cause any particular problems for the owner, with the exception of high vibration and noise loads. Weak point Traditionally, there are valves that have to be constantly adjusted.

ICE from Lada Kalina 11183 was installed on the fourteenth model solely to meet Euro-3 standards. It has typical disadvantages for a linear series and is no different.

The first sixteen-valve engine 21124 does not bend the valves, the gaps in which are adjusted by hydraulic pushers. However, the belt needs to be tightened after 15,000 km due to the large number of attachments. The second and last in the line of fourteenth ICE models, ICE 21126, has increased power. Besides typical faults if the timing belt breaks, the piston will bend the valve due to insufficient recess depth.

Engine tuning

For naturally aspirated engines, the following type of tuning is usually used:

  • receiver complete with 54 mm throttle body at the inlet;
  • straight-through spider 4/2/1 at the outlet;
  • camshaft Nuzhdin 10.93 or Dynamics 118 instead of the factory equipment.

The dynamics of the internal combustion engine will improve, the power will increase to 85 - 90 hp. With. Next is just lightening the crankshaft, modifying the intake manifold and milling the cylinder head.

For 16 valve engines, tuning has the same principles, since chipping it does not make sense. To achieve 120 l. With. You can increase the damper to 56 mm, use a direct-flow type exhaust, Nuzhdin 8.85 or Stolnikov 8.9 280 camshaft.

Thus, only one engine, modification 21126, bends the valves on the VAZ 2114. All other engines are considered safe and provide real resource about 270,000 km.

List of all regulators

Icon Check Engine under alarm- indicates a problem with the engine

All sensors in domestic “four” are installed in engine compartment, on the body, electrical circuits, and also on the gearbox. Almost all controllers are installed on the car during production, but some of them can be installed additionally.

The entire list of devices installed in the VAZ 2114 is given below:

  • engine fluid pressure;
  • coolant temperature;
  • antifreeze level in the system;
  • fuel level in the gas tank;
  • IAC - regulator idle move;
  • MAF - mass air flow;
  • level brake fluid in system;
  • TPS - throttle position;
  • movement speed;
  • DPKV - provisions crankshaft;
  • DPRV, also known as camshaft position sensor or phase sensor;
  • Lambda probe;
  • detonation;
  • uneven road surface;
  • outside air temperature (video author - Ivan Vasilievich).

Location and purpose of devices

We figured out what sensors are used on the VAZ 2114. But if you are renovating your " iron horse» yourself, then you will probably be interested to know where the main controllers are located.

Where are the VAZ 2114 sensors located and what functions do they perform:

  1. Engine fluid pressure controller. This element allows you to calculate insufficient pressure consumables V power unit. If on dashboard the corresponding icon starts to light up, this may indicate problems and malfunctions that have appeared in the operation of the motor. In the event that the indicator on the dashboard has been on for a long time, and the car owner does not take any action to repair his vehicle, this can lead to serious problems. For example, you will either have to do a major overhaul of the power unit, or if the situation is more complex, then it will need to be replaced altogether.
    It should be noted that the indicator on the dashboard may appear in several cases - when the level of consumables in the system decreases, when the filter element is clogged, when the oil pump breaks down, and also when there are wiring faults. If the engine fluid level has dropped significantly, then perhaps the problem lies in a leak, so it is necessary to find all leaks and eliminate them. Perhaps the indicator appeared on the dashboard as a result of its failure. As for the location, it may differ depending on the type of engine. For example, on engines with 8 valves, the controller is installed to the right and below the valve cover, in the block head. If we are talking about a 16-valve unit, then the meter is placed on the left end of the camshaft bearing housing. It should be borne in mind that if the regulator breaks down, it would be more advisable to replace it with a new one.
  2. Antifreeze temperature controller in the cooling system; this regulator is also called the engine temperature sensor. This device is located on the intake manifold of the so-called cylinder head cooling jacket. In accordance with the signal received from the device, information about the temperature status of the power unit is displayed on the dashboard. Thanks to it, the car enthusiast will be able to know to what temperature the engine has warmed up, and this data is extremely important, especially when the power unit overheats.
    As for checking the device, diagnostics can be done at home. To do this, you need to connect a multimeter to the mechanism and switch it to ohmmeter mode, and put the controller itself in a vessel with antifreeze. Next, the container heats up, and in accordance with the temperature change, resistance diagnostics are performed. If these data correspond (detailed table is provided in service book), then the DTOZH is operational.
  3. Antifreeze level meter in the cooling system. As the name implies, this device allows you to determine the volume of remaining consumables, so that if there is a shortage, the car owner can supplement the volume. The meter is mounted in an expansion tank with consumable liquid and it is equipped with a thread, so it is screwed into the mounting location, and power is connected to its end.
  4. Brake fluid level meter in the system. From the name it is clear why it is needed, because operating a car with low level"braking" can lead to tragic consequences. This itself is a float-type controller that is mounted in expansion tank with consumables.
  5. IAC or idle air regulator. This element is designed to ensure stable idle speed; it allows air into the power unit at idle speed bypassing the throttle position sensor. If the device fails, the idle speed will float. The part is mounted directly on the throttle, next to its damper.
  6. Mass air flow sensor - of all the regulators, this is the most expensive device. Using this controller, the control unit allows you to determine the volume of air consumed, as well as adjust the ratio of air and fuel to form a combustible mixture. The latter is subsequently supplied to the engine injectors. If the unit fails, this can lead to a decrease in engine power and problems with the engine idling. The part is mounted on the air filter element housing, not far from the inlet line.
  7. Speed. Mounted on the gearbox and allows the driver to monitor the speed at which the car is moving.
  8. Fuel level in the tank. The float-type device is located in the “four” gas tank. If it breaks down, the fuel volume will be displayed incorrectly on the dashboard.
  9. TPS is a unit that operates in conjunction with the idle air control; it is also called the gas pedal position sensor. This part allows you to determine the degree of throttle opening. If it breaks, the engine will not respond to pressing the gas pedal, and the engine speed may also increase arbitrarily. The mechanism is located directly on the throttle.
  10. DPKV is designed to synchronize the control unit and the vehicle engine. It is located near the generator unit drive pulley.
  11. DPRV, used to determine phased injection, is installed on the side of the air filter element, close to the cylinder head cover. In accordance with the position of the camshaft, the regulator transmits a signal to the control unit, resulting in injection before the valve opens. Fuel is thrown in simultaneously with the air flow.
  12. Lambda probe or . The regulator allows you to determine the amount of oxygen that is available in the exhaust system, as well as adjust the combustible mixture. Installed in the receiving manifold, next to the resonator. The device transmits an impulse to the control side about the volume of oxygen concentration in the exhaust gases.
  13. Detonations. The device detects vibrations in the operation of the power unit and automatically adjusts the ignition angle. In “fours” this part is mounted on cylinders 2 and 3, on the fan side.

Malfunctions

As for malfunctions, they can all be divided into several groups:

  1. Device failure. In this case, the problem can be solved by replacing or repairing it.
  2. Broken wire. The problem can be solved by replacing the wire.
  3. Poor contact. The contact is either cleaned from oxidation or replaced with a new one.

Detailed instructions for replacing the idle air control valve yourself are given in the video below (author - channel In Sandro's Garage).

The VAZ 2114 injector engine is a series of engines that were installed on the Lada 2114 vehicle. Like many Lada models, the 2114 model received several power unit options over all years of production. So, the technical characteristics of each of them were different. Let's consider the design of the 2114 engine, as well as issues of maintenance, tuning and repair.

Specifications

VAZ 2114 car

The technical characteristics of the VAZ 2114 engine are quite typical for the 2113-2115 series of cars. In addition, this power unit is developed on the basis of the “eight” engine, which has declared itself to be reliable and easy to repair. The car was produced from 2001 to 2013. During this period, the vehicle received five valuable power units.

VAZ 2114 engine structure

As was said earlier, the 2114 was equipped with five different power units, which differed in power and valve mechanism. Three of them had 8 valves, and the other two had 16. The gas distribution mechanism had a belt drive. Until 2007, the engine was equipped with a simple on-board computer, which did not regulate the operation of the engine based on sensor readings. Therefore, the motorist had to regulate the processes the old fashioned way, manually. Since 2007, an ECU was installed, which, receiving data from sensors, independently adjusted many processes.

Design features of the engine.

Since the second generation had the so-called the electronic unit The engine control is two-way, then it is worth considering what electrical circuit has been installed.

Electrical diagram of a VAZ 2114 car.

Main characteristics of the motor

All engines that were installed on the vehicle had approximately the same characteristics and design features. So, the motor is easy to service and repair with your own hands. Let's look at the main technical characteristics of the VAZ 2114 engine:

All engines were completed mechanical boxes 5-speed gears. Engine volume ranges from 1.5 to 1.6 liters. Large volume of power unit this car was not completed. Average power The VAZ 2114 engine produces 85 horsepower.

Motor maintenance

When the design and main technical characteristics inherent in the VAZ 2114 engine have been reviewed, it is necessary to consider maintenance and provide answers to questions that motorists are increasingly asking.

Maintenance

If you believe the plant, the manufacturer, the VAZ 2114 engine must be serviced every 12-15 thousand kilometers. It depends on what marking the motor is installed on the vehicle. Maintenance scheme for all engines installed on the “fourteenth” model:

  1. At the first maintenance, the oil is changed, oil filter and air filter element, as well as checking the functionality of all systems.
  2. The second maintenance is done after 12,000 km. In this case, it is necessary to change the oil and oil filter element.
  3. Third maintenance – 25,000 km, replacing not only the oil, but also the air filter, and ongoing repair of faults.
  4. After 45,000 km, it is necessary to replace the timing belt and roller so that the VAZ 2114 engine does not have to be overhauled.

Subsequent Maintenance goes according to 2 and 3 TO.

Frequently asked questions and their answers

The process of repairing a VAZ 2114 engine.

Many car enthusiasts on forums ask the same questions. Let's try to classify all of them, and also give answers according to factory standards and recommendations.

What kind of oil should be poured into the VAZ 2114 engine?

If you rely on the manufacturer's data, then the VAZ 2114 engine, depending on the type, pours different oils. So, what kind of oil should you put in the VAZ 2114? If you take it for an 8 valve engine, then ideally it would be suitable with the 10W-40 marking. If it is a 16 valve engine - 5W-30. In any case, the oil for the VAZ 2114 should be semi-synthetic.

What is the operating temperature of the engine?

Based on the manufacturer's data, the operating temperature of the motor for engines installed on models 2113-2115 is 87-103 degrees Celsius. After 105 degrees the electric fan turns on.

Where is the engine number on the VAZ 2114?

The engine number is quite easy to find. It is located on the gearbox side, near the thermostat. The engine number always has a pad on the cylinder block, which is located in a visible place.

What is the resource of ICE 2114?

The service life of the VAZ 2114 engine is 150 thousand km for an eight-valve power unit and 180,000 km for a 16-valve power unit. To extend the service life, you need to know what kind of oil to pour into the engine, as well as service it on time. Although driving style and careful operation of the car play an important role.

Do valves bend on VAZ 2114 engines?

Of course, like in any other engine, the VAZ 2114 has a valve mechanism that bends. This often happens due to overheating, when the head bends. The valves can also bend if the timing belt breaks.

What to do if the engine does not develop power and the speed drops?

In this case, it is worth carrying out a comprehensive diagnosis of the power unit. The issue may lie either in the inoperability of one of the sensors or in the mechanics. You can find the problem on your own or with the help of professionals at a car service center.

Engine malfunctions and repairs

Disassembled VAZ 2114 engine.

The fault diagram of the 2114 motor and its modifications is quite typical. Typically, the most common are floating speed, tripping, pump failure, as well as others that car owners are familiar with in detail. Where certain faults are located can be determined by carrying out diagnostic work.

After 150,000 km, the engine will need a bulkhead (overhaul). Every car enthusiast can repair his engine on his own, but many do not take risks and turn to a car service center.

For the VAZ 2114, repairs are carried out by analogy with the 2108 engine, since they are quite similar. In order to replace the timing belt you will have to fix it camshafts. The set of replacement operations includes changing the timing belt, a roller or two, as well as adjusting the valves.

To replace the water pump, you will have to fix the camshafts, just like to change the timing belt. Because the belt also passes through the pump, and therefore the process is quite complicated.

Engine tuning

Tuning version of the VAZ 2114 engine.

Tuning the VAZ 2114 engine is carried out typically for the entire series of power units installed on 2113-2115. As you know, there are two options for modifying the engine: mechanical and chip tuning. The modification scheme is quite simple, the mechanics are done first, and then the electronics. But many car enthusiasts only carry out chip tuning to reduce consumption, since the price of fuel is too high.

Chip tuning of the VAZ 2114 is carried out using special equipment and is aimed at increasing power or reducing fuel consumption. This type of work should be entrusted to professionals, since only they have the necessary skills and knowledge.

As for mechanical modifications, the scheme is standard. In case of complete modification of the motor, it must be completely disassembled. It is necessary to gain full access to the interior of the power unit. Next, the process of boring-honing and installation of new spare parts with light weight is carried out.

Installed turbine on a VAZ 2114 engine

After assembly, it is recommended to install a tuning version of the cooling and exhaust system, since combustion will occur with the release of more heat than before. Standard oil will not be suitable for the VAZ 2114 engine after tuning, so it is recommended that the modification process be done by professionals.

Conclusion

Installed on VAZ 2114 different variants engines, both eight and sixteen valve. They all had different technical characteristics and design features. But all modifications are quite repairable and easy to maintain. As for tuning, each motorist decides for himself how to modify the engine and for what purpose.

To independently repair a VAZ-2114 with an 8-valve injector, you need to know the structure and operating principle of the engine. With this knowledge, you can determine the cause of the malfunction without resorting to outside help.

VAZ series engines are equipped with a distributed fuel injection system, which improves driving performance and typically reduces the percentage of toxins in exhaust gases. There are two types of fuel injection systems: with feedback, as well as without it, they may differ from each other in details. Everything depends on the export or import of products.

Feedback injection is usually used in car models supplied abroad and is equipped with a neutralizer. The open-loop system (sold domestically) contains a CO potentiometer that regulates the exhaust gases.

Neutralizer

To change toxic elements and convert them into toxin-free components, the vehicle is equipped with a neutralizer. Its location is in the exhaust system, directly behind the muffler pipe.

For the high-quality functioning of this unit, it is necessary that the mixture supplied to the engine contains a certain proportion of air and fuel. This happens thanks to electronic system injection, which controls the distribution of fuel based on the efficiency of the load on the internal combustion engine.

Electronic control unit

This block monitors information coming from sensors and is responsible for controlling the fuel injection system.

The control unit contains a diagnostic system, thanks to which a system failure is recognized. It signals all problems occurring in the system through a light located on the dashboard - Check Engine. It also stores all errors that have ever occurred. Subsequently, their codes help to understand when diagnosing problems.

Memory

The ECU contains three types of memory. RAM is a kind of notebook. All temporary data is entered into it. The RAM microprocessor is located on the ECU board. To save all incoming information, it needs an uninterrupted supply of voltage.

ROM is an energy-independent memory that stores all data. The sequence of all performed actions is fixed in the PROM.

Sensors

The temperature sensor is a small thermostat in the cylinder head pipe; it is used to control the temperature of the antifreeze.

The knock sensor is screwed into the cylinder block and detects knocking phenomena occurring in the engine. If the slightest vibration occurs in the motor, the impulse is transmitted to it. After this, based on a signal emanating from the control unit, the ignition is adjusted, during which unwanted fuel flashes that lead to detonation are eliminated.

The oxygen level sensor is installed in a closed-loop system. Its mounting location is located in front of the muffler. The normal temperature reaches 360 degrees, and a special heating element is provided to actively warm up the motor.

The air flow sensor is mounted near the air filter. It consists of three elements, one of them determines the temperature environment, the rest are needed to maintain a certain temperature level exceeding that of the first. Air flow cools everything heating elements, and the ECU uses this information to determine air flow and sets the duration of opening or closing of the injectors.

The location of the CO potentiometer is the engine compartment (the wall of the air supply box). This element sends a signal to the computer used to adjust the desired proportion of air and fuel.

The vehicle speed sensor is located near the level dipstick motor oil. Through it, a signal is sent to the ECU similar to the speed of the drive wheels.

Synchronization sensor - located on the oil pump cover near the generator drive pulley. Based on the information coming from it, the control unit calculates the crankshaft speed and then sends a characteristic signal to the injectors.

Supply system

The air filter is located in the front part of the engine and is equipped with rubber retaining elements. If it becomes necessary to replace them, the corrugation is located on the same parallel with the center line of the car. The main function of the throttle pipe is determined by dosing the air flow entering the intake pipe. The air entering the engine is adjusted thanks to the throttle valve, which is connected to the accelerator pedal. The throttle pipe consists of two components: a position sensor throttle valve and idle air control.

Fuel system

It consists of many components: fuel pump, fuel pressure regulator, fuel filter, fuel line, injectors and ramp, thanks to which fuel enters the engine. The ramp is a strip on which the injectors and fuel pressure regulator are located, and is attached with two bolts to the intake pipe. The injectors are mounted on the fuel rail, its function is to supply fuel to the engine. An injector is an electromagnetic valve that opens and sprays fuel under pressure in a thin stream after it receives a corresponding impulse from the ECU. Upon contact with the heaters, the fuel evaporates and is fed through the needle pin into the combustion chamber.

In 2001, the VAZ line of cars was replenished with a five-door hatchback, popularly called the “four”. The VAZ 2114 engine was repeatedly modified and improved.

IN different years When released, the car was equipped with eight-valve engines of 1.5 liters and 1.6 liters.

Also, sixteen-valve internal combustion engines with a volume of 1.6 liters were installed on the cars. The model was produced until 2013.

1.5l

The main difference between the VAZ 2114 engine and the 21083 engine, on the basis of which it was developed, was the use of an injection system instead of an obsolete carburetor and a camshaft with modified phases. The connecting rods are attached to the pistons using a floating pin.

Installed on VAZ 2115, 21083, 21102, 21099, 21122, 2111, 2113, 21102, 21093.

1.6l

Thanks to the increase in height of the cylinder block (2.3 mm), it was possible to increase the piston stroke and engine volume to 1.6 liters. The designers have achieved greater throttle response and improved environmental performance of the VAZ 2114 engine.

The car received an increase in power (81 hp and 125 Nm of torque), but lost in efficiency. Now AI consumption is 95 V mixed cycle is 7.6 l/100 km.

The 1.6i engine was equipped with: VAZ 21112, 21101, 21121, 2113, 2115, Lada Granta and Lada Kalina.

16V 1.6i l VAZ 211440-24

The logical development of the Kalina engine was sixteen valve engine. VAZ 2114, equipped with a 124 engine, meets Euro-3 environmental requirements.

The piston stroke and cylinder diameter remained the same. Thanks to minor modifications, at 5 thousand rpm the engine develops maximum power of 89 hp. With. Consumption in the combined cycle was reduced to 7.5 liters. per hundred.

16V 1.6i (124) was also installed on the models: VAZ 21124, 21123 Coupe, 21104, 21114.

16V 1.6i l VAZ 211440-26

ICE 21126, also known as the Priora engine, received a number of significant improvements:

  • Federal Mogul lightweight connecting rod and piston group (39%);
  • smaller valve wells;
  • modified timing drive with automatic tension;
  • better cylinder honing;

Thanks to these changes, the engine received an increase of 9 liters. With. and a peak torque of 145 Nm. In the combined cycle, the four with a 126 engine consumes 7.2/100 km.

16V 1.6i (126) is also received by the Lada family (Priora, Kalina, Granta, Kalina of the second generation).

All modifications of the engine installed on the VAZ 2114 have a block cast from cast iron and injection system fuel injection. Despite the design solutions used to improve dynamic and environmental performance, the design of the VAZ 2114 engine has retained its simplicity and reasonable maintenance cost.

Operation and resource availability

An oil change should be done every 9-11 thousand km. Regardless of the modification, 3.2 liters will be required to change the oil. Recommended viscosity: 5W-30, 10W-40, 5W-40, 15W-40.

According to the manufacturer, the engine life is 150 thousand km. (200 thousand km for Priora motor). Practice has shown that with proper maintenance, the engine can cover up to 250 thousand km.

Failure to comply with maintenance standards and improper tuning of the VAZ 2114 engine significantly reduces its service life.

Features and Disadvantages

  • after a timing belt breaks, the valves remain unharmed;
  • Regular adjustment of valve clearances is required;
  • wear of cooling system components;
  • oil leaks from under the valve cover;
  • oil leakage from under the ignition distributor and fuel pump;
  • poor fastening of the exhaust manifold (solved by replacing steel nuts with brass ones);
  • unreliability of early injection systems.
  • A broken timing belt does not deform the valve;
  • the need for periodic valve adjustment;
  • increased noise and vibration load.
  • Thanks to the holes on the pistons, even with moderate sports shafts, if the timing belt breaks, the valves do not bend;
  • Every 15 thousand km you need to tighten the timing belt.
  • a broken timing belt leads to bending of the valves (the problem can be solved by installing plug-free pistons.

Popular faults

Due to the imperfect quality of the unit and the large number of low-quality spare parts, the motor and attachments require increased attention.

Main problems and possible causes:

  1. Unstable idling of the VAZ 2114, the engine stalls after starting. Cause – Coking of the idle speed controller (IAC), throttle position sensor, vacuum seal “drizzle”, unreliable signals from the mass air flow sensor;
  2. Starting has deteriorated, the engine is running rough - the reason may be: incorrect valve adjustment, lack of compression in one of the cylinders (the valve may have burned out), wear of the valve springs, air leaks (check the connections of the hoses and pipes going after the mass air flow sensor and to the vacuum valve, valve hose absorber purge, tight fit of injectors to the cylinder head), malfunction of the ignition module, spark plugs do not produce a spark, inoperability high voltage wires, incorrect valve timing (the timing belt may have slipped a few teeth);
  3. The VAZ 2114 engine has lost throttle response and does not pull. The breakdown is possible due to a faulty ignition module (symptoms appear when the engine is warm), clogged catalyst, fuel pump does not create the required pressure, dirty air filter, air leaks, carbon deposits on spark plugs, lack of compression;
  4. Extraneous knocking, noise and vibration of the VAZ 2114 engine. Breakdown may occur because valve clearances need adjustment, sagging valve springs, sagging seats, wear of the main bearings of the crankshaft or connecting rod bearings (it is possible that the pistons themselves are knocking), hydraulic compensators, wear of the engine mounts (pillows);
  5. Does not show the engine temperature of the VAZ 2114. Occurs due to a malfunction of the coolant temperature sensor (the sensor screwed into the cylinder head is responsible for the readings on the instrument panel), open circuit, oxidation of contacts, a malfunction in the indicator on the dashboard;
  6. The engine is heating up. Thermostat failure (liquid circulates only in the jacket engine cooling). When buying a thermostat, look in the instructions for what engine operating temperature it is designed for (for the engines in question this is 95-103 degrees); Damage to the water pump impeller, malfunction of the fan switch sensor, or the fan itself does not work.

For many owners, the standard dynamics of the VAZ 2114 are not enough. Engine tuning allows you to improve the dynamics and customize the character of the car.

As practice has shown, chip tuning of VAZ 2114 engines does not lead to tangible improvements.

Let's look at more serious improvements:

  1. For owners of eight-valve engines, the most in a simple way dynamics will improve cylinder head installation from a 16 valve engine. Modification of the 1.5l block is also possible.
  2. The easiest way to tune a VAZ 2114 engine is to install camshafts different from stock. For example, OKB Dynamics 108 will give an increase in the highs without a noticeable loss in the lows.
  3. By supplementing the shaft with a sliding timing gear and a suitable phase setting, you can get + 7 hp. With.
  4. Installing an enlarged throttle valve (54 mm), a receiver and a 4.2.1 spider will improve cylinder purging and give noticeable changes during acceleration (the level is close to Priora).
  5. Modified cylinder head, lighter valves and modified intake manifold paired with an increase in engine volume to 1.6 liters will allow you to achieve a power of 110 hp. With. Tuning up to 120 horsepower will take place without loss of resource.

The principle of improving the power characteristics of sixteen-valve engines is similar to the process of refining V8 1.5i l and V8 1.6i l. More evil camshafts, direct-flow exhaust, a receiver, an enlarged damper, a lightweight Priorov piston group, in the case of the Kalina engine (124) and proper tuning will give a significant increase in dynamics.

Regardless of the number of valves per cylinder, the power of the VAZ 2114 engine can be significantly increased by installing a compressor or turbocharging. Engines modified in this way easily reach 170–190 hp. With.

There are many different configurations and upgrade options available dynamic characteristics car. You can decide for yourself how to increase the power of the VAZ 2114 engine. Remember that the selection of mechanical modifications and software must match each other.

All cars of the Samara-2 family that came off the Volzhsky assembly line Automotive Factory, are staffed modern engines injection type, with an electronic distribution system for gasoline injection.

Fuel injection on a fuel injection engine

VAZ-2114 is no exception. For the fourteenth model, engineers developed a new power unit with the 2111 nomenclature. Despite the fact that in last years production, other engines were also installed in the VAZ 2114 - 21126, 21124, 21114 and 1183, the 2111 engine is the most common. We will talk about it in this article.

You will learn about the technical characteristics, nuances of repair and operation of the VAZ 2114 engine, what are the features of its design and how to overhaul the engine of the fourteenth with your own hands.

The VAZ 2114 engine, in comparison with the power units of classic VAZs, has one key difference - a fuel injection system, the operation of which is controlled by an ECU (electronic control unit).

Because electronics take everything into account important nuances: ratio of gasoline and oxygen in fuel mixture, required injection timing and composition exhaust gases, the engine of the fourteenth shows itself in the best possible way - it is durable, powerful and economical.

The 2111 engine is an 8-valve, 4-cylinder device with four strokes. The cylinder arrangement is in-line. The engine itself in the engine compartment is placed perpendicular to the direction of movement of the car.

The VAZ 2114 engine diagram looks like this:

  1. Tube for supplying cooling mixture;
  2. BC (cylinder block);
  3. Thermostat;
  4. Sensor that determines the temperature of the cooling mixture;
  5. Outlet pipe;
  6. BC valve;

  12. Device that regulates idle speed;
  13. Sensor that determines the position of the throttle valve;
  14. Receiver;
  15. Rear part of the housing of the gas mixture distribution unit;
  16. Front part of the body;
  17. Fuel injectors;
  18. Fuel rail plug;
  19. Fuel rail;
  20. Gasoline intake manifold;
  21. Intake manifold support (right);

  30. Flywheel.

The engine we are considering has a cast cylinder block, the oil supply holes in which are machined, and the holes for antifreeze are made during the casting process. The engine cylinders are also machined inside the monolithic structure.

At the bottom of the structure there are supports for the main bearings, the covers on which are an irreplaceable part of the engine - they are adjusted to size at the stage of manufacturing the supports, and it is impossible to find two covers of the same size.

Inside the supports there are inserts made of a steel-aluminum alloy, and inside the third support there are half rings that prevent axial displacement of the crankshaft.

The pistons of the VAZ 2114 engine are aluminum, with cast steel rings, the connecting rod is steel. The cylinder block of the fourteenth is placed on a metal tray, on top of which a vibration-damping lining is laid.

Owners of the fourteenth are advised to check the integrity of this lining from time to time, since when it wears out, the sump, which is a hollow container for storing oil, can be damaged when driving over uneven surfaces due to the pressure of the cylinder block.

The crankshaft, located under the cylinder block, is equipped with a mount for the flywheel. The lightweight flywheel on the VAZ 2114 has a special mark, through which its correct location on the crankshaft flange is selected - it must be placed strictly perpendicular to the connecting rod journal of cylinder No. 4.

Let's look at the main technical characteristics of the 2114 engine:

  • Torque – 166 Nm/3000 rpm;
  • Volume (l) – 1.5;
  • Number of cylinders – 4 (two valves each);
  • Cylinder diameter (mm) – 82;
  • Fuel compression ratio – 9.8;
  • Power (hp) – 78

It is worth noting that the design features of the engine make it possible to increase its power to 120 hp. without significant loss of operational life.

  • Gasoline consumption per 100 km (l) – 7.3;
  • Engine weight (kg) – 127.

According to the manufacturer, the resource of the power unit is 150 thousand km, but in practice, major repairs of the engine of the fourteenth are usually required in the region of 200-250 thousand km.

In 2010, 16-valve engines began to be installed on the VAZ 2114. This modification of the fourteenth was called “super-car”, in honor of Super-Avto CJSC, which was engaged in its production.

16 valve engine VAZ 2114

Technical characteristics of the 16v engine:

  • Torque - 131 Nm/3700 ​​rpm;
  • Volume (l) - 1.596;
  • Number of cylinders (mm) - 4 (diameter 82 mm, in-line arrangement);
  • Fuel compression ratio - 10.3;
  • Power (hp) - 89;
  • Max. speed (km/h) - 190;
  • Acceleration to 100 km/h (s) - 11.2;
  • Consumption per 100 km (l) - 7.6.

Repair of the VAZ 2114 engine should begin with emptying the oil and coolant containers. Next, you need to dismantle all the mounted components and clean the motor from oil and dust that has accumulated on it during operation. After this, you can start reassembling.

  1. We remove the fuel supply pipes;
  2. Remove the air supply and exhaust hoses;
  3. We remove the crankcase breather and cooling system pipes. Remove the throttle pipe;
  4. Next, you need to unscrew the receiver and fuel rail, which will make it possible to remove the injectors;
  5. We dismantle the manifold on the VAZ 2114, it is mounted on brackets, the nuts on which are unscrewed with a 13mm wrench;
  6. We disconnect and remove the wiring to the ignition module and unscrew the spark plugs. Remove the ignition sensor;
  7. We remove the tension belt from the generator, and then dismantle the entire structure. Together with the generator, we remove all the elements - strips and brackets with which it was fixed;
  8. We dismantle the generator pulley, having previously blocked the flywheel;
  9. Remove the camshaft drive along with the pulley and tension belt;
  10. Unscrew the pump, remove the thermostat and an exhaust manifold;
  11. Next in line is the oil pump for the VAZ: dismantle the filter and crankcase, then remove the pump itself;
  12. Next, we dismantle the piston block. To do this, you need to unscrew all the nuts on connecting rod bolts and remove the unit housing cover;
  13. We unscrew all the flange fastenings from the previously blocked flywheel and remove the disk;
  14. We unscrew the caps on the main bearings and remove all the lower bearings located in them;
  15. We dismantle the crankshaft. This must be done extremely carefully to prevent any deformation of the structure;
  16. Remove the half-rings of the stop and the upper liners.

VAZ 2114 engines that have traveled several hundred thousand kilometers have a fairly large number of worn parts. During the rebuilding process you will see this for yourself. All engine components that show serious signs of wear or damage must be replaced with new ones.

For the efficient operation of the injection power unit, the VAZ-2114 car system includes a large number of different mechanisms and automated devices. You can’t say that the “fourteenth” car is filled to capacity with electronics, but if you look under the hood, you can find all kinds of VAZ-2114 8-valve injector sensors.

The main purpose of electronics is to monitor the condition of vehicle components and assemblies. The received data is transmitted to the main “brain” center of the car. Thanks to this approach, the driver no longer needs to spend a long and exhausting time looking for reasons for deviations from the operation of a particular system. The ECU will provide all the information. What sensors are involved in the operation of the VAZ-2114 and where are they located?

General information about VAZ-2114 sensors

Sensors look like small mechanisms. However, their role in the operation of the entire vehicle system is simply colossal. They signal the remaining fuel in the gas tank, inform the driver of the coolant temperature, and determine the position of various engine elements in a certain operating mode. In order to know your car well and understand what could fail in a given situation, you need to know the entire list of mechanisms involved in the system.

We list all the sensors on the VAZ-2114 injector 8 valves, which are the most important:

  • Crankshaft positions.
  • Camshaft position sensor.
  • DTOZH.
  • Speed.
  • Idle move.
  • Lambda probe.

These devices are in most cases located in the engine compartment. Almost all of them are installed at the factory during vehicle assembly. But the driver himself can install some sensors at any suitable time. It is also important to know how each of these devices works and what primary task it performs.

You can often hear drivers with many years of experience calling this mechanism nothing other than a synchronization sensor. This name comes from the principle of operation of the device. The tasks of the DPKV are to synchronize the operation of the electronic unit and the gas distribution mechanism.

The VAZ-2114 is equipped with an inductive type DPKV. The cost of such a sensor is relatively small. If a vital controller for a car fails, most drivers prefer to immediately replace the device with a new one.

If the DPKV breaks down, further operation of the vehicle will become impossible. Without this mechanism, the fuel supply system will stop working, because the ECU will not receive information about when it is necessary to give a command to inject fuel into the cylinders. The location of the DPKV is in close proximity to the camshaft.

Electronics are responsible for fuel delivery in the VAZ-2114 car system. Without TPS, the control unit will not be able to determine the optimal time to supply gasoline. Deviations from the correct operation of the TPS lead to an increase in the amount of fuel consumed. The operation of many other car systems depends on the angle at which the remote control is located: cooling, fuel supply.

The TPS is located near the idle speed sensor. In the “fourteenth” system, the work of these two devices is closely linked.

When the TPS breaks down, the car begins to twitch in a certain position of the damper, and instability of engine operation is also noted. All VAZ-2114 8 valve sensors are interconnected in their operation, so two different devices sometimes exhibit the same symptoms of malfunction. If symptoms of a breakdown occur, it is necessary to take a comprehensive approach to checking all controllers.

Camshaft position sensor

This mechanism is located near the cylinder block. The main task is to transmit data to the ECU regarding the current operating cycle. Among specialists, the mechanism is called a Hall sensor. The operation of the device is based on the following principle: in accordance with the location of the crankshaft, the position of the gas distribution mechanism is determined. The data received by the sensor is reported to the electronic unit. Fuel is injected and the mixture is subsequently ignited.

Knock sensor, DTOZH, speed and others

In addition to the above mechanisms, other very important devices can be found in various corners of the engine compartment. The location of the VAZ-2114 injector sensors is quite chaotic, some are located directly on the power unit, others in other places - the gearbox, on electrical circuits.

Some equally important mechanisms include:

    1. The knock sensor is sensitive to various engine vibrations. Based on the received pulses, the ECU determines the qualitative composition of the mixture. Located on the cylinder block.

    1. Engine temperature sensor - the only and simple, but extremely important task assigned to this device is to monitor the coolant temperature.

    1. Speed ​​sensor – from the name itself it is clear that this controller is necessary to measure the speed of a car. The DS transmits impulses to the ECU, which processes them and determines the speed of the car; the resulting result is displayed on the instrument panel by the speedometer.

    1. Idling speed – not only reads information, but also corrects engine operation. DXH, using a special needle, controls the pipe - closes and opens. Due to this, the amount of oxygen supplied to the throttle assembly changes.

    1. Mass air flow sensor - reads the data and transmits it to the control unit, which, based on the information received, determines the optimal ratio of the various components of the fuel-air mixture. A breakdown of the air flow sensor leads to the fact that the car significantly loses power, and the driver begins to feel a significant increase in the amount of gasoline consumed by the car.

  1. DC - oxygen sensor, lambda probe. This controller is called differently among car enthusiasts, but the principle of its operation does not change. The DC informs the control unit about the amount of oxygen in the exhaust gases. The mechanism can be found in the receiving manifold.

These are the main and most significant sensors in the “fourteenth” system. It is also worth mentioning the FLS, which plays an important role - it determines the level of gasoline in the vehicle tank. Domestic drivers often experience difficulties with this device. Sometimes it works incorrectly and misinforms. But, as a rule, the FLS breaks down in old cars. You can repair the mechanism yourself, but it all depends on the severity of the breakdown.

Conclusion

To summarize, it is worth saying that the sensors on the VAZ-2114 injector 8 valves are located in different corners general design car. All of them play an extremely important role; their work is organized around the electronic control unit. If any controller breaks down, the driver will feel strange behavior in the car. At any time, you can diagnose and read ECU errors.
