2f3e5fd0 The operating valve of an admission is open (VSV is switched off)

Fig. 2.216. The scheme of operation of the operating admission valve in situation "is open"

The electronic control unit of the engine switches off VSV for reduction of duration of a cycle of a pulsation, at the same time the diaphragm of the executive mechanism is affected by atmospheric air, and the operating valve opens. When the operating valve is open, the effective length of a vpuksny collector decreases and peak efficiency of an admission is displaced to the area of high turns of the engine, thus providing big power in this area.
