The principle of operation of the air supply system
The main node of the circuit is the air flow meter (see Fig. 301). It is located between the air filter and damper. Its task is to constantly measure the amount of air supplied by the engine. The air is evenly distributed to the individual cylinders by means of an intake manifold (see Fig. 310).
