The VAZ 2107 can be considered progressive for the VAZ line of cars. Since this is the first car from this manufacturer to use an engine with an injection system, when other VAZ vehicles used a carburetor.

Some car owners were pleased with this innovation, but others were not. Of course, there are fans of one system, and there are others. But be that as it may, what's done is done. Therefore, let's figure out what are the advantages of such an engine over its predecessor and what are the main disadvantages.

As such, the injector was invented a long time ago. The first model was introduced in 1894, before the carburetor system was invented. But it turned out to be impossible to recreate such a model in practice at that time. Therefore, they forgot about the injector for a while and remembered only in the 40s of the last century.

Differences between carburetor and injector

If we talk about functions, then there are no fundamental differences - both systems perform the task of supplying fuel from the tank to the fuel rail, then to the cylinder. However, the difference lies precisely in the methods of supplying this very fuel.

In an engine that uses a carburetor design, the mixture of fuel and air enters the combustion chamber using a pressure difference. The downside of such a system is that implementing this method requires the power of the engine itself.

As for the injection system, the fuel enters directly into the combustion chamber under some pressure. But here the fuel ingress is controlled by a computer. This is one of the main advantages of this design. Since the system, which is controlled by electronics, uses fuel in precise dosages, which makes the engine more economical.

The main pros and cons of the carburetor and injector

A huge number of engine manufacturers are abandoning carburetor systems and using injectors. So what are the main reasons?

1. Less pollution environment. Injection engines produce approximately two times less harmful substances than their predecessors. We can say that this is main reason the fact that carburetors were abandoned. Since this system does not comply with established EURO - 3 standards;
2. Economical. An engine with such a system uses approximately 40-50 percent less fuel;
3. Increased power ratings. Thanks to the improved design, manufacturers were able to increase engine power by 15 percent. Also thanks to this, the dynamics of the car improves several times;
4. Quality and reliability. The fuel injected engine is very reliable. The presented system rarely breaks down;
5. Easy to start. Unlike a carburetor, there is no need to warm up the injector in cold weather;

Despite the large number of advantages, the injection system has unpleasant disadvantages:

1. Difficult to diagnose and repair. Due to the fact that the device is controlled electronically, it will be impossible to carry out diagnostics and repairs without special equipment and a professional in this field;
2. Price. The constituent elements of this system are not only high cost, but also low in suitability for repair;
3. Required high quality gasoline. If you use bad gasoline, then this will have a very bad effect on the reliability and performance of the system. When using fuel that contains a large amount of solid impurities, it will be necessary to regularly flush the injector;

The carburetor is still quite popular. There are the following reasons for this:

1. Simple repair. There is no need for expensive equipment to service the carburetor. Anyone who has at least some idea about engines can fix it at home;
2. Price. Spare parts for a carburetor are several times cheaper than for an injector;
3. Any quality of fuel can be used. This mechanism hardly senses the difference in fuel.

On a note. Vehicles with carburetor system You can even refuel AI-76 and this will not affect the quality of work.

And this is where the advantages of the carburetor end; as for the disadvantages, they are a complete reflection of the advantages of the injection system:

• high fuel consumption;
• In order to start an engine with a carburetor system in the cold, a long warm-up is required.

And these are not all the shortcomings.

Injector and VAZ 2107

The injection system is a solenoid valve.

This device operates in very difficult conditions and is subject to heavy loads, especially in Russian realities and in domestic cars. Therefore, the injector on 2107 requires good maintenance. Even if the system is slightly clogged, it can affect the supply and fuel economy. This reduces engine efficiency.

Therefore, if the following signs are detected, it is necessary to clean the injector:

1. Malfunction of ignition systems;
2. The engine runs rough;
3. Power reduction;
4. When you press the gas pedal, a “stumbling” occurs.

If we talk about the disadvantages of the VAZ 2107 injector, then here we can add only of all the above disadvantages of the injector system:

• Low location of the catalyst. Only 10 centimeters from the ground, so you should choose smooth roads, otherwise he might get hurt.

The VAZ 2107 injector diagram is shown in the image.

Modern injection engines have not bypassed the domestic auto industry. This is definitely a good thing. Since the injector has many advantages over the carburetor.

With the introduction of the injector system, the VAZ 2107 engine became more powerful and more reliable in operation. This should please all future car owners of this car.

The VAZ 2107 car was created on the basis of the 2105 model. New sedan designed for 5 seats, was equipped with a 5-speed manual transmission. The car was put into production in 1982.

Initially, a carburetor engine from a VAZ 2103 was used as a power unit. Subsequent models and modifications were also equipped with carburetor internal combustion engines. For export models 21073, a new injection unit was developed. It had sufficient power and was also economical. The engine capacity was 1.7 liters. Then they began to install injectors on all “sevens”. It was a more modern engine (VAZ 2107 injector) with a volume of 1.6 liters. This allowed us to ensure compliance with existing environmental standards.

Let's figure out what an injector is, look at the principles of its operation and technical characteristics.

History and design of the injector

The debate about which system is better among specialists and car enthusiasts still does not subside. But let's leave this debate to the professionals. And novice car enthusiasts just need to know how this system works and how it works.

It is not at all necessary that car enthusiasts will need this knowledge to do-it-yourself repairs. However, knowledge is power. This knowledge is needed at least so that the novice car enthusiast is not deceived by cunning mechanics from the service station around the corner.

The history of this device begins in 1951. It was then that the well-known company Bosch installed such an injection system on a 2-stroke engine of one sports car. Then, in 1954, the famous and popular car manufacturer Mercedes also began to equip its engines with a new system.

Serial use of injectors began in the late 70s. Even then it was clear that this device worked better than conventional carburetor systems.

As a result, injectors completely replaced their “ancestors”. All modern cars equipped with such distributed as well as direct electronic injection systems.

The principle of operation of the injector in the power system

The injection system is designed to supply fuel using direct injection using an injector directly into intake manifold cylinder. Therefore, cars with a distributed injection system are called injection cars.

The classification of the injection method depends on the principle on which the system operates, as well as where the injector is installed and how many there are in the car.

All modern cars perform fuel injection using a distributed system. That is, each cylinder has its own injector. The operating principles are based on signals from a microcontroller, which receives information from many sensors. Then, based on this information, the controller either opens or closes the injectors.

VAZ 2107 injector: device

VAZ 2107 cars have a distributed injection system. It works in conjunction with an electronic engine management system. It's called the ECU. Using numerous sensors, it controls the supply and quantity of air and fuel that enter the cylinders. Also, the ECU, if necessary, starts or turns off the fuel pump, controls the formation of a spark on the spark plugs, and also adjusts the ignition angles. In addition to all this, the ECU regulates the frequency at which the crankshaft rotates at idle, and also, if necessary, starts the cooling fan and controls the cooling system.

Scheme of operation of the injection power circuit on the VAZ 2107

There is nothing complicated here. This scheme should not cause any difficulties even for beginners.

Firstly, the power system starts with a tank in which the fuel is stored, and fuel filter. Then, using the fuel pump, the mixture passes through the filter to the fuel rail. A special pressure regulator is mounted on the ramp, which regulates the process of supplying fuel to the VAZ 2107 injector nozzles.

Using this regulator, a pressure of 300 mPa is created, and excess fuel is sent back to the tank. The injectors open and close using electrical impulses that come from the electronic control unit. They are designed to ensure simultaneous supply fuel mixture into the intake manifold of each cylinder at each crankshaft revolution.

How much of the combustible mixture enters the cylinders depends on the time at which the injectors are open. This time is adjusted by the controller based on information received from the sensors.

Sensors (VAZ 2107 injector) installed on the engine provide all the information necessary for this. For example, the crankshaft sensor provides information from which the controller calculates the time between pulses for the injectors. If the operating mode of the power unit is increased, the system increases the opening time of the injectors. The controller calculates the time based on information from throttle valve, as well as a mass air flow sensor.

The ECU constantly monitors the voltage in the car's electrical network, so if the voltage drops, the opening time of the injectors increases. All operating modes of the motor and injector are controlled by the controller. This ensures adjustment of the composition of the fuel mixture and operation of the injectors on the VAZ 2107 “injector” car.

Ignition system

Traditional devices are not used here. As systems providing ignition, the VAZ 2107 (injector) is equipped with one module, which consists of two coils, as well as electronics. The system does not use a single moving part.

How does the injection system work on the "seven"?

How much fuel is supplied through the injectors to the cylinders is controlled using an electrical impulse from the ECU. The block calculates the amount of fuel the engine needs and also determines how long the pulse will be.

When the crankshaft begins to rotate, the very first impulse from the sensor idle move forces the ECU to turn on all injectors. The very first injection takes place every time you start. How long the pulse lasts depends on the temperature.

When the driver turns on the ignition, the fuel pump relay is activated and creates pressure in the fuel line. Next, the computer checks the temperature and calculates how much air and fuel is needed to create the mixture, and then delivers it to the engine. The VAZ 2107 injector, by the way, is more economical than its carburetor counterparts. This is achieved through more accurate dosage of fuel.

Generator

The VAZ 2107 injector, in addition to all these devices and sensors for the correct operation of the injection system, is also equipped with a generator. It is necessary to charge batteries and power all electrical consumers and the injection system as well.

How does the VAZ 2107 model generator work? The injector doses fuel into the cylinder, after which the car is set in motion. At this moment, the generator generates the necessary voltage to charge the battery and power electrical equipment.

VAZ 2107: reviews

As for the reviews of the direct owners, they are, as always, very controversial. Many of the drivers and owners of this car complain about high fuel consumption and the low dynamics of the VAZ 2107 model. They don't criticize the injector. Also, many drivers say that they are satisfied with everything in the design of the car and in the design and operation of the power system. Some people don't like the product at all. Russian automobile industry, that’s why they criticize domestic cars in every possible way.

Today, if not all, then most drivers appreciate injection system injection is worth it. And many began to install injectors on conventional carburetor cars. Today you can purchase a new or used kit, which includes everything necessary for the system to operate.

How much does it cost to install an injector on a VAZ 2107? The price of this upgrade is about 20,000 rubles. But such a replacement will definitely pay for itself in the future.

So, we found out how the engine and generator work on the “seven”. The VAZ 2107 injector is much better than its carburetor counterpart.

The VAZ-2107 has been known to Soviet car enthusiasts for more than forty years. This modification is similar to the Italian Fiat. The main difference from it is appearance and some engine components.

This is one of the oldest models on the domestic market, therefore, both cash costs and time for repairs will require corresponding investments.

This largely depends on the frequency of operation of the machine and the applied loads.

Most novice car enthusiasts have no idea where to start repairing a VAZ-2107 engine. For simplicity, it should be explained that since the car is not new at all, consumes a sufficient amount of gasoline, and has lost its traction, there is no way it can drive uphill in last gear. Naturally, you have to “pull” on the third.

Result:

• heating the VAZ-2107 engine;
• the appearance of unnecessary noise;
• the appearance of a knock;
• overvoltage of the oil pressure pump.

All these troubles forced you to drive to your destination using the suction method.

As a result, an increased temperature of the VAZ-2107 engine is observed, and it begins to stall.

Your further actions can also be predicted. This:

1. Trying to find the root cause of the breakdown yourself.
2. Going to a service station for help.

Main causes of failure:

• Completely worn out camshafts and the appearance of rough burrs on them.
• Violation of the integrity of the spline on the oil pump shaft with parallel slagging of its filter with chips and other unnecessary debris.

What is the reason?

With such intense work of the power unit, the lubricating properties of the motor were lost, as a result of which the rubbing parts wore out and the motor jammed.

The service station carried out repairs and you have to pay a significant amount. What was done?

• chain tightening;
• replacing the oil pump with a new one;
• changing the engine oil with pre-washing it;
• changing the cylinder head;
• replacing most gaskets and oil filter;
• installing a new generator relay and replacing spark plugs.

What is the name of the engine in a VAZ-2107 car if it was repaired at a service station? And what can he do after the overhaul?

Such repairs cannot be called major. Because just as the car didn’t pull up the mountain, it won’t pull.

A major repair will be called a repair, the result of which will be the restoration of the previous traction and power of the unit by the machine.

Exist simple ways determine that the VAZ-2107 has lost engine power. They are:

1. Engine oil consumption is too high.
2. Reduced acceleration of the car during normal carburetor operation.
3. Availability exhaust gases dirty color and soot.
4. A large number of soot marks.

What are the reasons for the reduction in power of the power unit?

• violation of the fit of the pistons to the cylinder walls;
• loss of compression.

Malfunctions such as decreased compression, wear piston rings, changing the diameter of the cylinder working rings to the maximum may be the reason for carrying out

For those who decided to save money and repair the engine of a VAZ-2107 car with their own hands, the recommendations are given below.

• It is necessary to prepare a place for the event repair work engine. To do this, you will need a pit and a crane beam, since the engine will need to be removed somehow. Otherwise, the repair will be doomed to failure.
• To free up access to engine compartment the hood must be removed.
• Disconnecting the ground and removing the battery.
• Carrying out work to open the radiator and expansion tank by unscrewing all the necessary bolts.
• Draining antifreeze.
• Drain motor oil from the engine crankcase.
• Removal air filter and carburetor. These parts should be put aside as they will not be needed for work for a long time.
• Disconnecting a dangling hose from the fuel pump. To minimize the loss of gasoline, it is necessary to insert an M8 bolt into the gap.
• Removing the power unit.
• Disconnecting the pipes leading to the stove, coil and spark plug wires.

Internal work in the engine

• Filming the camshaft and timing sprocket.
• For unscrewing, you should stock up on a torque wrench.

This is one of the important procedures, and it is necessary to start it if you have practice in this matter. If you have no experience, check out detailed instructions on working with these screws and keys.

• Disconnection and complete removal
• Carefully inspect the pistons and cylinders regarding any embossed marks that appear.
• The time has come to climb into the inspection hole to remove the protection from the engine crankcase.
• De-energize the generator and remove it together with the belt.
• Complete removal of the starter from the car.
• Removing all pipes from the cooling system, radiator and water pump.

Get ready for your garage to resemble a flea market. Next, you will have to unscrew all the clutch housing fasteners, nuts and enlist the help of a partner to hang the removed engine on the beam.

1. Removing the oil filter, clutch, flywheel, timing chain, crankshaft sprocket.
2. Carrying out a crankshaft inspection.
3. Transition to working with the cylinder block.

If you are not scared by the above work, you can begin to overhaul the engine of the VAZ-2107 car.

Engine and service station

It should be noted that there is no way to do without the help of a service station, since you will have to turn to them for the services of cylinder block boring and grinding crankshaft. You may also need to perform other work.

For a VAZ-2107 car, engine repairs are carried out by proven auto repair shops with certain machines and qualified specialists.

When carrying out repairs yourself, you need to know the list of main malfunctions that can occur with the VAZ-2107 engine.

VAZ-2107 engine - malfunctions

1. Problems with the operation of the power system, up to complete failure of operation fuel pump and both pipelines.

2. The presence of debris in the fuel and air jets.

3. Violation of the operation of the starting device membranes associated with their damage.

4. Serviceability problems high voltage wires, spark plugs and distributor until they completely fail.

5. Failure of the pump, presence of debris in the filter.

6. Maximum wear of the cylinder with the piston, camshaft, timing belt.

The VAZ-2107 injection engine also has a number of faults that you can fix yourself.

Motor malfunctions

A clean unit is not only an indicator of the car enthusiast’s love for his vehicle, but also the main factor in increasing its power and operating efficiency. It contributes to better vehicle performance and economical fuel consumption. Problems with the VAZ-2107 engine (injector) associated with contamination contribute to a decrease in the volume of injected fuel and disruption of the composition of the air-fuel mixture.

Electronic systems can “heal” clogged injectors. But this treatment is not the main one, since the problem remains on the VAZ-2107 car. The engine (photo below) stops pulling normally, consumption increases, etc.

The main signs of blockage are:

• uneven operation of the motor;
• intermittent ignition;
• loss of power;
• Troubleshooting or failure of the engine.

If one of these signs is confirmed, you should immediately repair the VAZ-2107 engine.

Ignoring this requirement will lead to irreparable damage.

Repairs can be carried out either independently or with the assistance of specialists.

Some experts believe that to correct the situation, the following actions must be taken:

After completely unscrew, thoroughly clean or change the spark plugs.

The explanation for this action is quite simple: the presence of a large amount of soot, which settles on the spark plugs and slows down their operation.

You can also change the oil and filters, since the ingress of solvent into the oil leads to a decrease in its quality.

Anyway, important point control remains over technical condition your car and timely troubleshooting of VAZ-2107 cars.

An engine whose price today ranges from 50 to 55 thousand rubles. It is not difficult to purchase.

The specified power unit is sold in almost every car store. big city. These can be either conventional carburetor or injection.

Carburetor ones are much less common than injection ones. This is due to the fact that the VAZ-2107 injection engine is equipped electronic systems management. And many car enthusiasts, having such an opportunity, changed old motor on new.

Secondary market

Many drivers prefer to save money and purchase a used engine, for which the price ranges from 20 to 2 thousand rubles. with a mileage of no more than 50 thousand km.

It is worth considering that when purchasing a used engine, to be sure of its quality characteristics, you will have to carry out diagnostics. If you are satisfied with the results, you can buy it with confidence.

So, we found out how to repair the power unit of a VAZ-Seven car.

The VAZ 2107 engine is a four-cylinder power unit with four strokes. On our website we will look at the main operating systems of this engine

28 Aug

One of the key parts of an internal combustion engine is the camshaft. Over time, wear appears on it and on the support bearings and the motor requires qualified intervention. The VAZ 2107 camshaft can be replaced independently. To do this, you will need a set of metalworking tools and knowledge about the features of setting up the gas distribution mechanism. Functions and design of the camshaft The VAZ 2107 camshaft (injector and carburetor) synchronizes ...

29 Aug

Replacing the cylinder head gasket of a VAZ 2107 is not so complicated as it is a responsible operation. At self-service"Seven" every car owner has to deal with this work. Internal organization engine is the same for the entire line of “classics”, therefore the order of advice on replacing the cylinder head gasket is equally applicable when repairing engines from the “first” to the “seventh” model. When to change the gasket...

The VAZ 2107 has long become a classic domestic auto industry. However, not all owners know that the model is ideal for tuning and various upgrades. For example, you can significantly optimize the dynamic properties of the “seven” by replacing the motor. The VAZ 2107 easily tolerates all innovations in terms of engine modifications.

What engines is the VAZ 2107 equipped with?

The VAZ 2107 model was produced from 1982 to 2012. Over the 30 years of its existence, the car has been repeatedly refined and changed to more accurately meet modern requirements. Initially, the “Seven” was conceived as a car with rear wheel drive small class sedan. However, in some countries the VAZ 2107 was refined and modified, which is why it can be considered a universal car model.

Depending on the year of manufacture and the country of origin (at different times, the VAZ 2107 was produced not only by the Russian AvtoVAZ, but also by factories in European and Asian countries), the model was equipped with various types musculoskeletal systems:

• LADA-2107 (engine 2103, 1.5 l, 8 cells, carburetor);
• LADA-21072 (engine 2105, 1.3 l, 8 cl., carburetor, timing belt drive);
• LADA-21073 (engine 1.7 l, 8 cells, mono injection - export version for the European market);
• LADA-21074 (engine 2106, 1.6 l, 8 cl., carburetor);
• LADA-21070 (engine 2103, 1.5 l, 8 cl., carburetor);
• LADA-2107–20 (engine 2104, 1.5 l, 8 cells, distributed injection, Euro-2);
• LADA-2107–71 (engine 1.4 l, 66 hp, engine 21034 for A-76 gasoline, version for China);
• LADA-21074–20 (engine 21067–10, 1.6 l, 8 cl., distributed injection, Euro-2);
• LADA-21074–30 (engine 21067–20, 1.6 l, 8 cl., distributed injection, Euro-3);
• (engine 21067, 1.6 l, 53 kW/72.7 hp 8 cells, injector, catalyst) (2007);
• LADA-21077 (engine 2105, 1.3 l, 8 cl., carburetor, timing belt drive - export version for the UK);
• LADA-21078 (engine 2106, 1.6 l, 8 cl., carburetor - export version for the UK);
• LADA-21079 (rotary piston engine 1.3 l, 140 hp, originally created for the needs of the Ministry of Internal Affairs and the KGB);
• LADA-2107 ZNG (engine 21213, 1.7 l, 8 cells, central injection).

That is, in total there were 14 versions in the VAZ 2107 line - either with carburetor engines or with injection ones.

Read about the device injection engines VAZ 2107:

Technical characteristics of VAZ 2107 (carburetor)

The VAZ 2107 was initially equipped with a 1.5 and 1.6 liter carburetor. In the USSR in 1980–1990, almost all produced models were equipped with engines of this size - this power was quite enough for trips around the city and country roads. The engine uses AI-92 gasoline to create the air-fuel mixture. There were also 1.3 and 1.2 liter carburetors, but they were not particularly popular.

The carburetor on the “seven” does not have large dimensions: the device is 18.5 cm wide, 16 cm long, 21.5 cm high. The total weight of the entire assembled mechanism (without fuel) is 2.79 kg. The engine works with spark plugs of a certain type - brand A17DVR or A17DV-10*.

The maximum power was calculated according to GOST 14846: 54.8 kW (or 74.5 horsepower).

The diameter of the working cylinders is 79 mm, while the piston stroke can reach 80 mm. The established order of operation of the cylinders is carried out according to the 1-3-4-2 scheme (every auto mechanic needs to know this scheme, since if the cylinders are not started in an coordinated manner, the operation of the carburetor will be disrupted).

The crankshaft size is 50.795 mm, the shaft itself rotates at a speed of 5400 rpm. When viewed from the front of the car (radiator side), the crankshaft rotates clockwise. The flywheel installed on the model has an outer diameter of 277.5 mm.

Check out the possibilities for tuning the VAZ 2107 carburetor:

The lubrication system on VAZ 2107 carburetors is combined, that is, the rubbing parts are lubricated both under pressure and by splashing. If you follow the recommendations of AvtoVAZ engineers, then you need to fill the carburetor engine of the “Seven” with oils that meet the API SG/CD standard. It is also recommended to select lubricant according SAE classification(Society of Automotive Engineers in the USA). Thus, if we combine these two principles of oil selection, then carburetor engine It’s better to fill in “sevens”:

• oils produced by Lukoil in the Lux and Super versions;
• Esso brand oils;
• lubricants Shell Helix Super;
• Norsi Extra oils.

AvtoVAZ has established acceptable oil consumption during vehicle operation. Thus, a loss of 0.7 liters of oil per 1000 kilometers is considered acceptable (of course, if there are no leaks).

Where does this rate of 700g per 1000 come from??? This is more like the GAZ-53 norm, at least in the farm where I worked at one time they gave a liter of oil for about 200 liters of gasoline. I wrote purely on my own occasion - I always kept MAX oil. in the crankcase, and did not leak or drip from anywhere, and when replacing the level was 2 matches below MAX. there was, and it was over 8000. This is normal oil consumption, as in the book “natural oil consumption for waste.” And when did it become when replacing MIN. I put it on capital, and, as it turned out, it was not in vain

Carburetor engine life up to overhaul relatively small - approximately 150–200 thousand kilometers. However, due to the simplicity of the design, major repairs will not be required large investments, while the updated motor will operate in the same mode as the new one. In general, the service life of the VAZ 2107 engine greatly depends on the driver’s driving style and care:

It depends on how you drive and what kind of oil you use. Ideally - 200 thousand, then capital is guaranteed

Enlightened

I used 270 thousand, I would have used more, but an accident forced me to disassemble it and replace everything that was needed without boring.

Where is the engine number

Each model vehicle, produced at the factory, is equipped with a motor with a personal number. So, the engine number on the “seven” is its identification number, which can be used to determine the identity of the stolen car and its history.

The engine number is stamped on the cylinder block on the left side, immediately below the distributor. In addition, the number is duplicated in the summary table, which is attached below the air supply housing. The metal plate contains information about the car, such as model, body number, model and number of the engine unit, equipment, etc.

What engine can be installed on a VAZ 2107 instead of the standard one?

Some car enthusiasts who are accustomed to upgrading cars with their own hands decide to replace installed motor to a more productive one. Like any other car, the “Seven” can be converted and equipped with an engine from another car, but a number of rules must be followed:

1. The replacement engine must exactly match the dimensions and weight of the standard device. Otherwise, there may be problems with the operation of the new motor.
2. The new engine must be mated to the existing transmission.
3. The power of the new power unit cannot be greatly overestimated (no more than 150 hp).

Motors from other VAZ models

Of course, first of all, the owners of the “Seven” turn their attention to the engines of other VAZ models. The best option(slightly more powerful and more durable) - this is a carburetor from a VAZ 2114. It fully matches the dimensions of the VAZ 2107 carburetor, but is a more modern and productive device. In addition, you can install the engine with a VAZ 2114 practically without any modifications - the only problems may arise with the RPD, but they are easily solved.

Motors from earlier VAZ models (2104, 2106) are also quite suitable in their dimensions and weight to replace the VAZ 2107 motor, however, replacement will not be advisable, since outdated devices will not give the car dynamics and durability.

Engines from foreign cars

The VAZ 2107 can also be equipped with an engine from an imported car. Ideal for replacement power units from the Fiat and Nissan brands. The thing is that the progenitor of VAZ engines were Fiat engines, which also served as the basis for the development of Nissan engines.

Therefore, engines from these foreign cars can be installed on the “Seven” without any alterations or modifications.

Rotary engine

There was a period in the history of AvtoVAZ when some car models (including the “seven”) were equipped rotary piston engines. Initially, such installations were highly productive, but the VAZ 2107 with such engines had many disadvantages:

Today, rotary motors are installed only on Mazda models, so if you wish, you can purchase such a power unit at a showroom or in official Mazda stores

A new rotary engine can be installed on the VAZ 2107, but the design of the car itself will not allow for maximum optimization of all the capabilities of the car. Therefore, rotary engines are not popular among VAZ 2107 owners.

Diesel engines

Car enthusiasts, in order to save on fuel, sometimes replace gasoline power units with diesel ones. On a VAZ 2107 you can also carry out this procedure. Again, for replacement it is better to take engines from Fiat and Nissan. Diesel engines more economical than gasoline, but require increased attention from a car enthusiast, as they are very capricious in terms of maintenance.

The undoubted advantage of diesel is lower fuel consumption. I really don’t know how much VAZ diesel consumes. But our price for Euro diesel fuel is almost equal to 92 gasoline. Namely, one dollar per liter without a few kopecks…. like this

Thus, the VAZ 2107 carburetor was initially designed for typical loads and a short service life before the need for repair. However, the repair itself is considered a simpler and more accessible procedure than, for example, the overhaul of an injection engine. In addition, the nuances of the “Seven” design give owners a chance to install engines from other car models in order to get the quality of work that is required.
