INPUT/OUTPUT SIGNAL CHART
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
In the medium speed range, the ECM sends the ON signal to the VIAS control solenoid valve. This signal
introduces the intake manifold vacuum into the power valve actuator and therefore closes the power valve.

Under this condition, the pressure waves of the exhaust stroke do not disturb the pressure waves of the intake
stroke of each opposite bank. Therefore, charging efficiency is increased together with the effect of the long
intake passage.
However, in the high speed range, the ECM sends the OFF signal to the VIAS control solenoid valve and the
power valve is opened. Under this condition, the pressure waves of intake stroke are resonant with those of
each opposite bank exhaust stroke. Therefore, charging efficiency is also increased.
In addition, both valves 1 and 2 are opened or closed in other ranges mentioned above. Thus maximum
charging efficiency is obtained for the various driving conditions.
