The VAZ 2114 car is a high-quality modification of the most successful creation of the Volga Automobile Plant VAZ 2109. The model received the name "Samara 2". Her presentation was held in 2001. Whereas the car entered mass production only in 2003. Later, an even more advanced 2114 16-valve valve vase appeared on the domestic market. We will consider this model in more detail in our review.

Differences of VAZ 2114 from VAZ 2109

Improvements to the VAZ 2114 in comparison with the prototype were more than serious. They touched both the appearance and the technical part of the car.

2114 designers made a number of changes:

• new front and rear bumpers installed;
• updated hood cover;
• the model received advanced optics;
• the radiator was lined;
• a package of moldings has been added.

The interior of the car has changed even more. Here the instrument panel and steering wheel were completely replaced. To improve the comfort of passengers and the driver, the engineers replaced the outdated heater. Also, 2114 received a new front wiper.

Engine VAZ 2114

The most anticipated changes in the VAZ 2109 concerned precisely the power plant. In the first generation, the model used an 8-valve 2114 engine. It had a working volume of 1.5 liters. In the next update of the VAZ 2114, which took place in 2007, this engine was replaced with an improved one with a volume of 1.6 liters.

Installing a 16-valve engine on the VAZ 2114 was a real breakthrough model. This modernization was carried out entirely under the control of Super-Avto CJSC, which is part of AvtoVaz OJSC. The most important characteristic of the 16 valve vaz 2114 is the maximum power of 89 hp. Thus, the car on the technical side came close to the budget foreign cars.

For comparison, we suggest you consider the following table of dynamic indicators:

Road characteristics of the VAZ 2114

In addition to the fact that a 16-valve engine was installed on the model, the VAZ 2114 was significantly converted to improve road properties. The gearbox of the machine with a gear ratio of 3.7 received a new package of "closed" bearings, which allowed to significantly increase the reliability and performance of the system, in particular the torque of the car.

For the braking system of the 16-valve VAZ 2114, engineers used larger in diameter (up to 200) than in 2109 clutch brake discs. In addition, the brake cooling system was improved, which made it possible to achieve not only safety, but also reliability again.

Designers managed to achieve great success in terms of car stability. This was mainly possible due to the installation of shock absorbers of increased energy intensity, as well as racks from the 2107 model. This set of procedures led to increased body rigidity, stability on the road, maneuverability and durability.

Price for VAZ 2114

Of course, most owners of domestic cars choose VAZ automobiles precisely because of their low cost. The price of the 16 valve vaz 2114 is in the same acceptable range, but at the same time you can count not only on profitability, but also on a fairly good performance of this vehicle.

Prices today for the 16-valve model fluctuate around 300 thousand rubles.

Many motorists, especially beginners, who just purchased the VAZ-2114, thought about how the 8-valve injection engine installed on this car is arranged. In this article, the motor device, the main characteristics, as well as the dismantling and repair features, will be considered. This information will be very useful for beginners and those who do not know how the main power unit is arranged.

Characteristics of 8 valve engine

Many motorists remember how in the late 90s of the 20th century and at the beginning of the 2000s, VAZ 2108-09, which was also called Samara, was popular on CIS roads. These cars became legendary in that era. Due to its high popularity, AvtoVAZ plant decided to resume production of these models with some modifications.

VAZ-2114 engine under the hood

Firstly, the VAZ-2114 received a modified engine. In fact, this is the injector version of Samara. Although some features she received from modern engines. If we consider in more detail, the Samara-2 engine (this type is installed on the VAZ-2114) is a mixture of two engine options in one: from the VAZ 2108 and VAZ 2110.

Many motorists Samara-2 power unit was to their taste and they loved it. The main indicator was - ease of repair and inexpensive spare parts. So, the 8-valve engine has become the standard indicator of "price-quality".

When the basic information has been considered, you can go directly to the consideration of the characteristics of the motor.

Dismantling and repair: basic facts

Therefore, we consider the main operations aimed at removing the engine from the car:

1. At the preliminary stage, disassembly is necessary, as well as coolant from the system.
2. Another point that can not be missed is to turn off the car. This is necessary in order not to short circuit the system.
3. Disconnect the fuel system.
4. We dismantle the units that supply air to the engine.
5. We disconnect the throttle, as well as all remaining air pipes and tubes of the cooling system.
6. We dismantle the injection system and the receiver.
7. We shoot completely.
8. We disassemble the gas distribution mechanism.
9.   and pump.
10. Now, you can dismantle the collector.
11. Remove the pan, oil filter and pump.
12. Disconnect the gearbox and remove the clutch. The gearbox can also be dismantled for convenience.
13. Remove the cylinder head.
14. We dismantle the power unit.
15. We carry out the final disassembly.

Overhaul of the power unit will require more in-depth knowledge of the design and principle of engine operation, but if desired, each motorist is able to figure it out and carry out these operations with his own hands.

It is worth noting that when diagnosing malfunctions, it is worth carefully and carefully inspecting every detail for defects.

conclusions

The device of the VAZ-2114 8-valve injection engine is quite similar to the first generations of this engine - Samara. Of course, the designers made many changes to the features of the power unit, but in many respects they remained similar. Repair and maintenance of this engine must be carried out regularly, which will also reduce the wear of parts that are located inside.

If interruptions regularly occur during the operation of the car engine, and the sound coming from the exhaust pipe is more like a tractor growling, this indicates that your engine is troit. This problem needs to be addressed, and promptly.

  The main causes of triple

If you say that your engine is troit, many will answer - the cylinder does not work. But such an argument is not entirely correct, since the cylinder stops working properly. However, there may be several reasons for this:

• The compression in the cylinders is too low;
• The spark plug is faulty or partially does not fulfill its functions;
• Valves do not fit well due to prolonged lack of adjustment;
• The nozzles are dirty or overfilled, therefore they need to be replaced;
• The oxygen sensor has stopped functioning;
• The high-voltage spark plug wire got damaged;
• Ignition coil defective;
• DPKV (crankshaft position sensor) does not work;
• The computer (electronic control unit) broke down;
• The timing belt has flown off or simply jumped to several links;
• The air filter is out of order or dirty.

Some problems literally immediately manifest themselves in the form of a failed cylinder, but others can manifest themselves only after some time. And this is the most undesirable scenario.

The primary signs of a problem that can inform a cylinder breakdown are:

1. The vibration increases, because the rhythm of the valves and other rotating parts of the gearbox and power unit is broken.
2. Fuel consumption increases markedly as the injection system has stopped working properly.
3. An unpleasant characteristic odor is heard from the exhaust pipe, which is explained by a high level of concentration of harmful impurities and unburned fuel.
4. The power of the power unit drops noticeably, which negatively affects the dynamics and maneuverability of the car.

If you notice that the engine is troit, but have not taken any measures, this soon threatens you with a complete failure of the engine, which may not be possible to repair. When the injector 8 valve engine is troit on the VAZ 2114, fuel constantly enters the idle cylinder.   It does not burn, but mixes with oil, then passes into the crankcase. If the process continues for a long time, the oil loses viscosity, ceases to play the role of a lubricant, the parts work at maximum loads, the metal turns into chips. There is nothing good about this, frankly.

  What to do?

There are a number of activities that are recommended to be carried out when it detects that the engine is troit.   All of them will provide an answer to certain questions. So get ready to devote a lot of time to your car.

The first thing to do is to identify a failed cylinder.   He is not alone there. To do this, you need:

1. Open the hood while starting the engine;
2. Listen and remember the sound your engine is making;
3. Take turns to remove the wires from the candles. If you remove the high-voltage wire, the sound should change. If the sound did not change when you removed the next high voltage, congratulations, you found a faulty cylinder.

Now dismantle the problem candle and check it for functionality.   To do this, you will need a special key designed specifically for removing spark plugs:

1. Pay attention to the electrode. If it is clean, whole, but there is a lot of burning on the head, most likely there is a large amount of dust in the combustion chamber. This indicates a malfunction of the air filter in the air supply system;
2. If a burnout is present on the head and electrode, which has noticeably burned out, the mixture enters poor, combustion occurs with premature ignition;
3. If the head is burning, but the electrode is intact, the mixture was rich, and the ignition was delayed;
4. Check for spark. If it is, then the problem needs to be looked further. When there is no spark, it is recommended to replace it with a new one and check the engine performance with a new spark plug.

If your car with impressive mileage is enough, it is recommended to perform the following operations to identify the causes of “triple”:

1. Replace spark plugs;
2. Dismantle the old high-rises and exchange them for new, high-quality ones. Sometimes banal microcracks on them lead to breakdowns and failure of the entire power unit;
3. Measure the compression in the cylinder that is not working. If you identify abnormalities, you may determine that the valve has burnt out or a problem in the rings;
4. Adjust the valves. In general, a similar procedure is carried out with a frequency of 15-20 thousand kilometers for the purpose of prevention;
5. Check if the ignition coil is working. A common problem for the VAZ 2114. Trying to repair it is not worth it, it is better to immediately change to a new one. It will not cost you a lot of money;
6. Replace the old air filter with a new similar unit;
7. Check that the timing belt is installed and functioning correctly.

If even these measures did not give any result, we recommend that you try out a few more effective methods to restore the engine's performance:

1. Check the operation of the electronic control unit. If problems are found, immediately replace the old electronic control unit with a new one;
2. Check the functionality of the fuel supply system. In some cases, you will have to get to the nozzles;
3. Analyze the operation of the oxygen sensor. It is subject to repair, but it would be better to immediately replace the device;
4. Make sure the crankshaft position sensor is working. This is determined using the electronic control unit. It will give an error that indicates a malfunction. With problems with the sensor, there is nothing left to do but change it to a new one.

  What to do if troit at idle

Also a fairly common situation, the causes of which there are a total of three.

1. There were problems with the supply of fuel.   It is necessary to flush the fuel system and clean the nozzles with ultrasound.
2. There is a malfunction in the ignition system.   In such a situation, it is recommended to change the spark plugs, check the operation of the ignition coil, and also install a new set of high-voltage wires.
3. Valves are not adjusted properly.   You will need to adjust the valves. If the situation requires more drastic measures, then the valves will have to be changed.

Situations when the engine is troit are found in a huge number of cars. The model of the domestic manufacturer AvtoVAZ represented by VAZ 2114 is no exception. This is not a sentence for your engine. It is simply necessary to promptly take appropriate measures.

If you interfere with the operation of the unit at the first sign of "triple", you will be able to avoid complicated and expensive repairs. But when the situation starts to drift and the site check is postponed day after day for later, get ready to spend a lot of money soon or even look for a new engine to replace the old one.

The volume of the VAZ 2114 engine and its characteristics changed and improved throughout the entire production period, from 2001 to December 2013. On the first batch, injector 8-valve units with a volume of 1.5 liters were installed. After the modernization of 2007, the “fourteenth” put new engines with a volume of 1.6 liters. The new production VAZ-11183-1000260 engines received the 3rd class of environmental friendliness, Euro-3.

The most powerful of all VAZ units was assembled and installed on the Lada Priora in 2010. The power of this power plant was 98 horsepower. A common feature of all engines of the VAZ 2114 model is that they are 4-stroke, have the same distributed fuel injection system. Fuel is supplied to the engine cylinders thanks to the installed nozzles.

Today, this method of powering engines is the most efficient of all fuel delivery schemes. The motors have a standard, decent appearance, and their camshaft is located on top. For cooling the units, a closed-type liquid system is used. Some mechanisms are lubricated with oil under pressure, some by spraying oil.

Characteristics of engines VAZ 2114

A very common engine model on the VAZ 2114 was an engine with a total capacity of 81.6 liters. from. with a serial number of VAZ 21114. This is a line type of power plant using an injection power system. The cylinder block is made of cast iron. The speed of the power unit reaches 5200 rpm. For high-quality operation, the engine is fueled with AI-95 gasoline.

Unlike its predecessor (VAZ 2111), in the updated VAZ 21114, due to the installation of an improved crank and an increase in the stroke of the piston system, the engine capacity increased by 0.1 liters. The total volume of the VAZ 21114 engine was 1.6 liters. In addition, it has become much more powerful. The minus of the increase in volume was a decrease in torque.

The piston stroke of such a motor on the VAZ 2114 reaches 71 mm. The diameter of the cylinder is 82 mm. Engine displacement varies from 1499 to 2114 cm³. Torque - 116 Nm / 3000 rpm. Fuel consumption in the city reaches 8.8 liters, on the highway it is much lower - 5.7 liters per 100 km. Oil consumption - 50 g / 1000 km. The mass of the 2114 engine is 127 kg.

  The resource of the unit according to the factory data is 150 thousand km., Actually - up to 250 thousand km. Definitely, the VAZ 2114 will not work for adrenalinists and amateurs to drive on the highway. This option is perfect for business, confident people. The car perfectly copes with the need to carry heavy trailers and more.

If you want to have a faster option, it is better to opt for a VAZ 2111 one and a half liter engine. The reduced stroke of the piston system allows the engine to gain speed faster.

Selection of the number of engine valves

Engine selection largely depends on the number of valves installed. The early VAZ 2114 models featured engines with 8 valves. After 2007, eight-valve engines were replaced by motors with 16-valve heads. Valves of internal combustion engines are used to intake air-fuel mixture and exhaust gas. Accordingly, the higher the valve capacity, the stronger and more powerful the motor.

It is easy to conclude that the throughput of gases through the head with 8 valves is much lower than through the 16-valve. Despite the fact that 8-valve engines do not work well at high frequencies, they give excellent performance when traction at low speeds.

16 valve engine

An engine with 16 valves can allow more gases to pass through itself, due to which the car accelerates faster. Alas, this design also has drawbacks, the main of which is the deformation of the valves themselves. 16-valve engines have not passed the test of time, so eight-valves are still considered more reliable.

When choosing an engine for a VAZ 2114 car, you must be guided by the following principles. A 16-valve engine (1.6 L) or an 8-valve (1.5 L) is selected if high speed and high torque are required. With an emphasis on stable and powerful traction at low speeds, an engine with 8 valves of 1.6 liters is the best option.

Causes and repair of engine malfunctions

As already mentioned, according to AvtoVAZ, the maximum resource of the VAZ 2114 engine is 150 thousand km. With normal and timely maintenance, the motor can work out even more. The standard operating temperature range is from 95 to 103 ° C. An oil change should take place on a warm VAZ 2114 engine every 10-15 thousand km. When the first signals about a car malfunction appear, you must contact the station or find the cause yourself. The most common engine problems.

1. Floating engine revs. As a rule, this happens in new cars and at idle. If the car is without a run, go to the diagnostics, repairs must be made under warranty. The causes of the malfunction may be the idle speed regulator, the throttle position sensor or the vacuum apparatus.
2. The car engine stalls on the go (floating engine speeds plus problems with the mass air flow sensor) - the reasons for the breakdown are the same.
3. Uneven engine operation (troit). Measure compression of the cylinders. If one of them has low compression, then the valve or head burned out there. If the difference in measurements is small, then adjust the pressure in the valves or replace the gasket. If the compression measurements did not show deviations, then the ignition module must be checked.
4. The engine does not heat up to normal operating temperature. The reason lies in the faulty thermostat.
5. Noises and taps in the engine. As a rule, the reason is poor valve adjustment. If sounds are amplified when you press the gas pedal, you need to go to the specialists. Problems may arise in connecting rod or crankshaft bearings or in cylinder pistons.

For the effective operation of the injection power unit in the VAZ-2114 car system, a large number of various mechanisms and automated devices are included. You can’t say that the “fourteenth” car filled to failure with electronics, but if you look under the hood, you can find all kinds of sensors VAZ-2114 8 valves injector.

The main purpose of electronics is to monitor the condition of components and assemblies of the car. 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 deviation from the operation of a particular system. All information will be provided by the computer. What sensors are involved in the work of the VAZ-2114 and where are they located?

General information about the VAZ-2114 sensors

Sensors externally are small mechanisms. However, their role in the operation of the entire car system is simply colossal. They signal the remaining fuel in the gas tank, inform the driver of the coolant temperature, determine the position of various engine elements in a certain operating mode. To know your car well and understand what could fail in a given situation, you need to know the whole 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 position.
• 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 the assembly of the car. But the driver himself can install some sensors at any suitable time for this. It is also important to know how each of these devices works, and which priority task it performs.

You can often hear how drivers with many years of experience call this mechanism nothing more than a synchronization sensor. This name came from the principle of the device. In tasks DPKV synchronize the operation of the electronic unit and the gas distribution mechanism.

An inductive type DPKV is installed on the VAZ-2114. The cost of such a sensor is relatively small. In the event of a failure of the controller vital for the car, most drivers prefer to immediately replace the device with a new instance.

If DPKV breaks down, then further operation of the car 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 close proximity to the camshaft.

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

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

In the event of a failure of the TPS, the car begins to twitch in a certain position of the damper; engine instability is also noted. All sensors of the VAZ-2114 8 valves are paired in their work, therefore, two different devices are sometimes characterized by the same signs of malfunction. In case of symptoms of failure, it is necessary to comprehensively approach the verification of all controllers.

Camshaft position sensor

This mechanism is located near the cylinder block. The main task is to transmit ECU data regarding the current cycle of work. 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 communicated to the electronic unit. There is an injection of fuel and subsequent ignition of the mixture.

Knock sensor, DTOZH, speed and others

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

Among the no less important mechanisms are:

1. 1. Knock sensor - sensitive to various vibrations of the motor. Based on the received pulses, the computer determines the quality of the mixture. Located on the cylinder block.

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

1. 1. Speed \u200b\u200bsensor - from the name itself it is clear that this controller is necessary to measure the speed of movement of a car. DS transmits impulses to the computer, which processes them and determines the speed of the car, the result is displayed on the instrument panel speedometer.

1. 1. Idling - not only reads information, but also adjusts the operation of the motor. DXX using a special needle controls the nozzle - closes and opens. Due to this, the amount of oxygen supplied to the throttle assembly changes.

1. 1. DMRV - reads the data and transfers it to the control unit, which on the basis of the received information determines the optimal ratio of the various components of the fuel-air mixture. Damage to the DMRV causes the car to significantly lose its power indicator, and the driver begins to feel a significant increase in the amount of gasoline consumed by the car.

1. DK - oxygen sensor, lambda probe. This controller is called differently among motorists, but the principle of its operation does not change from this. DK informs the control unit about the amount of oxygen in the exhaust gases. You can detect the mechanism 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. With this device, often domestic drivers experience difficulties. Sometimes it does not work properly, misinforms. But, as a rule, FLS breaks down in old cars. You can repair the mechanism yourself, but it all depends on the severity of the breakdown.

Conclusion

Summing up, it is worth saying that the sensors on the VAZ-2114 injector 8 valves are located in different corners of the overall design of the car. All of them play an extremely important role, their work is built under the electronic control unit. In the event of a failure of any controller, the driver will feel strange behavior in the machine. At any time, you can carry out diagnostics and read ECU errors.
