VARIABLE INDUCTION AIR SYSTEM

In the medium speed range, the power valves are closed. 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, charg-

ing efficiency is increased together with the effect of the long intake passage.

However, in the high speed range, the power valves are open. 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.
