The carburettor VAZ 2105 is an aggregate designed for the preparation of a combustible mixture, different in the ratio of gasoline and air, depending on the operating conditions of the engine and its feeding into the cylinders of the latter.
It consists of the following functional parts:
Carburetor VAZ 2105 (as well as any othercar) regulates the flow of air and fuel. As a result of this, the combustion chamber is no longer gasoline, but a fuel-air mixture enriched with oxygen. Due to this, the fuel lights up and moves the pistons. Accordingly, the energy from the engine is transferred to the wheels of the VAZ 2105.
Carburettor and its operation principle
The air flow is regulated by the throttle position. Each time you press the accelerator, the amount of air gradually increases, and when you release
It is unambiguous that the most important part of the mechanismfeeding the finished mixture into the combustion chamber is a Venturi tube. It is special in that its dimensions decrease from the edge to the cent, and then increase again. While the engine is running through the carburetor VAZ 2105 and the Venturi tube, a small air flow passes. As the air moves to the center, where the diameter is minimal, a low pressure is created. As soon as the diameter of the venturi starts to increase again, the pressure is equalized.
Through this hole, the fuel-air mixtureis fed into the intake manifold and then enters the combustion chamber. When the engine is running, the pressure in the collector decreases (below atmospheric pressure), and this, in turn, leads to a decrease in pressure in the part itself. Naturally, since the pressure level is higher, air from the side of the mechanism will flow into it through the intake manifold and bypass channels into the combustion chamber. Passing through the carburetor, it will capture petrol from the fuel chamber and mix with it, thereby creating a ready-mixed fuel mixture.
