2.3.9.12. Air inlet control system

The entrance branch pipe of the air filter is divided into two cameras, the operating valve of an air inlet and the executive mechanism are installed in one of cameras. Reduction of noise on an admission in the range of small turns and increase in power in the range of big turns was as a result reached.
When the engine works in the range of low and average turns, the control system by means of the operating valve of an air inlet closes one camera of an entrance branch pipe of the air filter.

Fig. 2.217. Scheme of a control system of an air inlet: 1 – the operating air inlet valve; 2 – VSV valve; 3 – executive mechanism


When the engine works in the range of big turns, the control system by means of the operating valve of an air inlet opens both cameras of an entrance branch pipe of the air filter.
