To guarantee optimum efficiency on high frequencies of rotation of the engine and a capacity maximum on lower frequencies of rotation of the engine, models with 16 valves have an inlet collector with variable section of a path. The system is called ACAV ("a variable acoustic characteristic induction").
The inlet collector is divided in two paths of various length and diameter: a long path (for low power) length 650 mm and diameter 36 mm and a short path (for high capacity) length 370 mm and diameter 45 mm.
On each end of a casing assemblage with a vacuum diaphragm is established. Each diaphragm is connected with an axis of the throttle valve through a pusher. Vacuum diaphragms are connected with электрически the operated electromagnetic valve which is in turn connected with the vacuum pump of brake system. The pump is established at an end face of a head of the block of cylinders.
At frequencies of rotation of the engine below 1800 turns in a minute and more than 5080 turns in a minute ECU the electromagnetic valve closes, disconnecting vacuum from diaphragms, and throttle valves закрывыются. With valves short paths of giving of air and air stream are closed arrives through a long path.
