Carburetor engine on the VAZ 2107.

VAZ 2107- five-seater a car classic layout with a front longitudinal arrangement of the power unit and rear drive wheels. Engine - four-cylinder, four-stroke, eight-valve, in-line, carburetor or fuel injection system. The body of the supporting structure, all-metal, welded. body type - sedan.

On the car VAZ 2107 is installed carbureted engine models VAZ 2103 with a working volume of 1.5 liters. The modification of the VAZ 21074 car is distinguished by the engine of the VAZ 2106 model with a working volume of 1.6 liters.

IN last years production of this model, modifications of the VAZ 2107-20 car with a VAZ 2104 engine with a working volume of 1.5 liters and VAZ 21074-20 with a VAZ 21067 engine with a working volume of 1.6 liters were produced, equipped with fuel injection, mechanical part (cylinder block, connecting rod and piston group , crankshaft) of these engines is respectively identical to the VAZ 2103 and VAZ 2106 engines. More powerful generators and starters with planetary gears are installed on the VAZ 2104 and VAZ 21067 engines. The installation of engines with distributed fuel injection on vehicles, as well as the use of a gasoline vapor recovery system and catalytic converters in exhaust systems, made it possible to reduce the toxicity of exhaust gases and fuel consumption, and increase the reliability of starting the engine in cold weather. Body, chassis and transmission remained unchanged.

Predecessor - VAZ 2105, successor - Lada Granta.

Engine for VAZ-2107 can be supplied both from domestic and from imported manufacturers.

This type of improvement on the base model is considered tuning, and if it is done by oneself, then one can earn approval and hear words of admiration not only from drivers, but also from those who have never driven a car. Confirmation of this - video:

Reviews are only positive:

The boys are real craftsmen.
Great CDs, love it.
The engine is such that there are no words!
Great job: the piston is exactly 100 in diameter.
How cool they connected the box with the engine from the GAZelle and rear axle. Virtuosi!
The guys are just handsome, they managed to do this with their own hands, which is not a pity to praise.
In addition to what has been said, take some advice: it is worth putting the bumper on stronger and in general then the tuning was 100% successful.

For some future car owners, the question is more serious: which engine to prefer -? Let's hear what experienced drivers have to say.

Mikhail, 40 years old, is the owner of a VAZ-2107 with a carburetor engine. He drives his second car with an injection unit. Ready to give comparative analysis two systems. His seven was the last model of the classic version, designed for economical fuel consumption, slightly increased dynamics. What actually happened?

Carburetor engine: comparative characteristics

To begin with, it is worth touching on the dynamics of a Zhiguli engine with an injector. What was said in the previous paragraph was not confirmed. Moreover, the problems have only intensified. The injection system did not reduce fuel consumption: such an engine began to accelerate even more slowly than its fellow carburetor. Many owners of such machines sin on the new "brains": the electronics think a little slow, but if you put it in, it should change for the better.

The manufacturer does not agree, he can not do a frisky foal. While carbureted engine goes a few steps ahead. You can’t talk about fuel consumption, it doesn’t please even the injection engine 2107 at all. Even the same driving style for a distance of 100 km suggests that it eats half a liter more than the second version of the car.

Injection engine: the second part

There are problems, both with one engine and with the other. The new injector is completely electronic, which means that replacing the ECU with 2107 in the event of a breakdown is possible only on the condition that it will significantly empty your wallet. If you change the entire injection system to the end, then it is better not to do this, but immediately buy a new car.

You can talk about two air flow sensors separately: their replacement will cost 30,000 rubles. For the carburetor, the situation is different: it can be completely replaced with a new one, discarding a third of the above amount. There are no ideal options for a carburetor either. Its repair will be 2-3 thousand rubles less. Is it worth it to boil so much for this money?

Once the work under the hood is done, you can work on the box. Fiat has a larger one, so first you have to change the mounting frame. Blame the long 5th gear. It's okay, collect cardan shaft from 2 parts, where imported elements will stand in front, and native Zhiguli ones in the back.

Vibrations are also easy to pacify: shorten the splines on the front of the cardan by 2 centimeters. After the alteration, they were just at hand.

Now that's all, but if one of you is eager to perform feats, then you can get a blessing in the church or from the leadership of this site.

VAZ-2107: it's time to fill the engine with new oil

According to the rules for Maintenance cars of the 2107 series, you need to flush the entire engine lubrication system after 30,000 km. Drain the old oil, while it is forbidden to unscrew to the end oil filter. Pour into the flushing agent up to the "MIN" mark on your dipstick, start the engine, let it run for Idling minutes 7-10 min. Drain the residue, replace the oil filter. Add engine oil keeping track of its level.

How to change the oil in a VAZ-2107 car engine? The labor process does not represent. Check out the step by step guide:

Prepare a capacity of 5-6 liters.
Warm up the engine.
Install your car on a viewing hole or drive into a flyover.
Remove the oil filler cap.
Remove the air filter housing.
Using a 12 mm (hexagonal) wrench, open the drain plug of the crankcase drain pan
Drain the oil from the engine into a prepared container.
Take a puller as an assistant to unscrew the oil filter.
Clean the threads of the plug with a rag drain hole, wrap it up.
Pour only fresh oil into a brand new oil filter and do not forget to lubricate the rubber gasket located right there with it.
Screw the filter onto the fitting, after the gasket and the mating ring come into contact, turn the filter 3/4 turn to the right.
Fill the engine with oil.
Wait 3 minutes, check its level with a dipstick.
Install the cover back.
Run the engine for a couple of minutes, stop it, check the oil level, test for leaks from the gaskets.

Everything worked out? Yes, you are just a professional! Don't want to get to know? You can learn a lot of interesting things if you become a regular visitor to the tuning section. For now, you can only be a student, but remember how children come to first grade and how a small member of society grows up. This also happens to those who service the car.

The rear-wheel drive class B sedan, VAZ 2107 is known all over the world. So, in the UK, the "sevens" were known as Lada Riva 1500 GLS, in Canada - as Dennis Signet, in a number of European countries - as Lada Nova or VAZ 2107.

Work on the VAZ 2107 began back in 1976, and the task was really difficult: to reduce the harmfulness of exhaust emissions and fuel consumption, to increase safety and comfort. Moreover, the changes had to be carried out in accordance with the requirements of the global automotive industry. As a result, it was supposed to turn out - and turned out - a luxury, fashion version. Moreover, it turned out to be so stable and image that even twenty years later, being an outdated model in almost all respects, it still did not fall in price, despite the absolute and obvious loss to competitors.

Engine Specifications

During the industrial implementation of the VAZ 2107 model, cars bearing this name were equipped with various engines- from a one and a half liter, 8-valve carburetor, to a rotary piston engine with a power of 140 Horse power. In total, more than ten modifications of the VAZ 2107 were produced.

car transmission

With all the many changes that have occurred with the VAZ 2107 model for almost 20 years of its assembly, one thing has remained unchanged - this is the transmission. The gearbox in all versions and modifications was only mechanical. Of course, on the one hand, such a transmission is more reliable, on the other hand, it is less convenient, especially for novice motorists.

The car 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. VAZ 2107 easily "tolerates" all the innovations in terms of engine refinement.

What engines is equipped with a VAZ 2107

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 finalized and modified, which is why it can be considered a universal car model.

Depending on the year of manufacture and the country of manufacture (at different times, 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 motor apparatus:

LADA-2107 (engine 2103, 1.5 l, 8 cells, carburetor);
LADA-21072 (engine 2105, 1.3 l, 8 cells, carburetor, timing belt drive);
LADA-21073 (engine 1.7 l, 8 cells, single injection - export version for the European market);
LADA-21074 (engine 2106, 1.6 l, 8 cells, carburetor);
LADA-21070 (engine 2103, 1.5 l, 8 cells, 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 cells, distributed injection, Euro-2);
LADA-21074–30 (engine 21067–20, 1.6 l, 8 cells, distributed injection, Euro-3);
(engine 21067, 1.6 l, 53 kW / 72.7 hp 8 cells, injector, catalyst) (2007 onwards);
LADA-21077 (engine 2105, 1.3 l, 8 cells, carburetor, timing belt drive - export version for the UK);
LADA-21078 (engine 2106, 1.6 l, 8 cells, carburetor - export version for Great Britain);
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, there were 14 versions in the VAZ 2107 line - either with carburetor engines or injection engines.

Read about the device injection engines VAZ 2107:

Specifications VAZ 2107 (carburetor)

On the VAZ 2107, a carburetor with a volume of 1.5 and 1.6 liters was originally installed. In the USSR in 1980–1990, almost all models produced were equipped with engines of this volume - this power was enough for trips around the city and country roads. The engine uses AI-92 gasoline to create an air-fuel mixture. There were also carburetors with a volume of 1.3 and 1.2 liters, but they were not very 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 mechanism assembly (without fuel) is 2.79 kg. The motor 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 scheme 1-3-4-2 (this scheme must be known to every car mechanic, since if the cylinders are not started, the operation of the carburetor will be disrupted).

The size of the crankshaft 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 of tuning the VAZ 2107 carburetor:

The lubrication system on VAZ 2107 carburetors is combined, that is, lubrication of rubbing parts is carried out both under pressure and by spraying. If you follow the recommendations of AvtoVAZ engineers, then you need to fill in the carburetor engine of the "seven" with oils that meet the API SG / CD standard. It is also recommended to select a lubricant according to SAE classification(Society of Automotive Engineers in the USA). Thus, if we combine these two principles for selecting oils, then it is better to fill in the carburetor engine of the "seven":

oils produced by Lukoil of the versions "Lux" and "Super";
Esso brand oils;
lubricant products Shell Helix super;
oils "Norcy Extra".

AvtoVAZ has set the permissible oil consumption during the operation of the car. So, the 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 on 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 nowhere did it flow or drip from anywhere, and when replacing the level by 2 matches below MAX. was, and this is for 8000. This is normal oil consumption, as in the book "natural oil consumption for waste." And when it became when replacing MIN. put on capital, and, as it turned out, not in vain

The resource of the carburetor engine is up to overhaul relatively small - about 150-200 thousand kilometers. However, due to the simplicity of the design, overhaul will not require big investments, while the updated motor will work in the same mode as the new one. In general, the resource of the VAZ 2107 engine is highly dependent on the driving style and diligence of the driver:

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

enlightened

I went 270 thousand, I would have gone more, but an accident forced him to disassemble and replaced 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, by which it is possible to establish 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 from the bottom of the air intake housing. On a metal plate, such data about the car as model, body number, model and number of the engine unit, equipment, etc. are knocked out.

What engine can be put on a VAZ 2107 instead of a standard one

Some motorists who are used to upgrading cars with their own hands decide to replace installed motor to be more productive. Like any other car, the "seven" can be redone and equipped with an engine from another car, but a number of rules should be observed:

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.
The new engine needs to mate with the existing transmission.
You can not greatly overestimate the power of the new power unit (no more than 150 hp).

Motors from other VAZ models

Of course, the first thing the owners of the "seven" turn their attention to the engines of other VAZ models. The best option(a little more powerful and more durable) - this is a carburetor with a VAZ 2114. It fully corresponds to the dimensions of the VAZ 2107 carburetor, but is a more modern and productive device. In addition, you can install a motor with a VAZ 2114 with virtually no alterations - the only problems can arise with the RPD, but they are easily solved.

Motors from earlier VAZ models (2104, 2106) are also quite suitable in terms of their dimensions and weight for the place of 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

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

Therefore, the engines from these foreign cars can be installed on the "seven" without any alterations and modifications.

rotary engine

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

Today, rotary motors are installed only on Mazda models, therefore, if desired, you can purchase such a power unit at disassembly or in official Mazda stores

You can install a new rotary engine on the VAZ 2107, but the design of the car itself will not allow you to optimize all the capabilities of the car as much as possible. Therefore, rotary engines are not popular among VAZ 2107 owners.

Diesel engines

Motorists, in order to save on fuel, sometimes change gasoline power units to diesel ones. On the VAZ 2107, you can also carry out such a procedure. Again, for replacement, it is better to take motors from Fiat and Nissan. Diesel engines more economical than gasoline, but require heightened attention from a motorist, as they are very capricious in terms of service.

the undoubted plus of a diesel engine is lower fuel consumption. I really don’t know how much a VAZ diesel eats. But here the price of a Euro solarium is almost equal to the 92nd benz. Namely, one dollar per liter without a few kopecks .... like this

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