In 1982, the Volga Automobile Plant produced a new model VAZ 2107. Initially, it was a car of the carburetor type. Engine size on different versions of cars differed. Model VAZ 21074 injector has an engine capacity of 1.6 liters, which exactly corresponds to the volume of the engine VAZ 21074 with a carburetor engine from the "six".

In general, the car was created on the basis of the VAZ 2105. The injection engine is more economical and began to be installed on the VAZ 21074 from 2006, especially to meet the conditions for environmental safety.

VAZ 2107, as well as its modifications have become the undisputed leaders of the Russian automotive industry due to the good price-quality ratio. The VAZ 21074 carburetor borrowed its engine from the VAZ 2106, and the injector VAZ 21074 from the model 21067.

Technical characteristics VAZ 21074

For the VAZ 21074 injector has its own technical characteristics that determine its work. The body type of the car is a sedan with 4 doors and 5 seats. Car load capacity 400 kg. Baggage weight on the roof should not exceed 50 kg. The average clearance of a car is 16.4 cm. But its minimum value is 9 cm to the neutralizer, which must be considered when driving on poor-quality roads. The maximum speed of this car is up to 150 km / h. Acceleration to 100 km / h is carried out in 16-19 seconds.

The engine VAZ 21074 injector is an inline four-cylinder with a cylinder diameter of 7.9 cm and a piston stroke of 8 cm. The power supply system with distributed injection. Engine power 73.6 liters. with. with a working volume of 1.6 liters and 5000 rev / min. Regarding the transmission VAZ 21074 injector technical characteristics can be identified as follows. The car is set manual 5-speed gearbox. Machine with rear wheel drive.

Chassis cars represented by two front suspension independent independent on two levers and rear dependent suspension (with a rigid beam). The ground clearance of this car is at a high level, well, it’s a Russian car. The brake system is represented by a front disc brake mechanism and a rear drum mechanism.

In general, the characteristics of the VAZ 21074 injector indicate that the car is not bad and will be able to serve its owner for a long time. It is reliable in operation, but it’s impossible to talk about significant engine efficiency, since fuel consumption averages 6.8–9.6 liters per 100 km, depending on the driving pattern.

How does the control scheme VAZ 21074 injector

VAZ 21074 with an injection engine type has its own characteristics. First, it is an electronic control of the engine. Such a system clearly controls the composition of the fuel mixture. Also running and running the fuel pump, which is turned on and off electronically. Such control is exercised over all parts of the engine.

The scheme of the VAZ 21074 injector consists of the following main components: the electronic unit, several sensors connecting the wires. On the dashboard there is a warning lamp that lights up in the event of malfunctions in the operation of system components. When the car starts its work and the engine starts, it starts checking its work. The signal lamp turns on first, and then, if everything is in order, goes out. If during the operation of the car the lamp lights up, then this indicates a possible malfunction of the engine.

In the VAZ 21074 injector generator installed three-phase AC. It has a built-in rectifier and voltage regulator.

The most important element of the electronic circuit is the control unit. It is he who is engaged in the development of signals to control the operation of the engine and the processing of the sensors from the performance indicators of parts of the system. The unit has built-in memory, the data in which is stored even in the absence of power.

Sensors are used to generate signals about the work, for example, a crankshaft and others, which allows you to synchronize the work of the elements of the system among themselves.

In general, the correct operation of the VAZ 21074 injector allows you to give the car a minimum of attention and periodically check it on special diagnostic equipment. But the carburetor engine is more whimsical and will require more attention, as it will have to periodically clean, adjust and tune. For example, very often do tuning VAZ 2109 (carburetor).

It is also worth noting that the price of the VAZ 21074 (injector) is affordable (about $ 4000 on average, if you search, you can find it for $ 2000, but you still have to tinker with it), which is certainly an additional advantage along with efficiency and the reliability of the car.

And finally, a video on how the VAZ 21074 injector accelerates to 150 km / h:
