What is the carburettor of the 21083 VAZ?

The carburetor is the basis of the fuel system of each vehicle. On all VAZ cars of the eighth and ninth family the well-known 21083 Solex carburetor is used, the main task of which is to prepare a combustible mixture for its further supply to the combustion chamber of the engine. In other words, this device serves to mix gasoline with air in certain proportions. What is noteworthy, for 1 cubic centimeter of fuel carburettor 21083 delivers 15 cubic centimeters of oxygen. The G8 rides almost on air alone.

Carburetor VAZ-21083: the device

This mechanism includes the following elements:

• Econostat.
• The float mechanism.
• Transitional system of the secondary chamber.
• The main dosing system of the primary and secondary chambers.
• Economizer with pneumatic control.
• The mechanism of control of the shutters.
• Accelerating pump.
• The EPHC system.
• Starting device.
• The system of forced ventilation of the crankcase.

"Solex" itself consists of two parts - the upper and lower parts, in which all the above elements and mechanisms are fixed.

Below we will consider what the main elements of this carburetor are for.

Gasoline with a special pump is pumped from the fuel tank along the main lines into the float chamber. The latter is a small container for temporary storage of liquid. With the help of a float the system regulates the level of fuel supply to the chamber. This part must always be adjusted. Otherwise, the fuel-air mixture will be excessively enriched, and the G-8 will consume 10-20 percent more gasoline, which is prepared by the VAZ-21083 carburetor. Adjustment of the float should always be made as soon as the vehicle has started consuming more fuel. It is also worth noting that after a long idle the gasoline level is rapidly falling, which makes it impossible to start the engine. In this case, motorists recommend manually pumping fuel into the carburetor of the 21083 VAZ with a lever on the gasoline pump.

As we know, the more oxygen moves, the more fuel it can pick up. For this, there is a diffuser in the carburettor system. It is a small detail tapering near the hole that leads into the float chamber. Accelerating pump is a device that increases the power of the motor when the accelerator pedal is depressed.

The air damper (suction) also plays a significant role in the fuel supply system. This part is at the top of the carburetor. It serves to regulate the flow of oxygen that enters the system from the air filter. Thanks to the air damper, the car is easier to start in winter, and after a long cooling ICE.

By means of a throttle заслонки in the carburettor of 21083 th VAZ the optimum quantity of fuel gets. This mechanism is connected to the gas pedal in the car's interior, and with each press it increases the flow of liquid.
