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 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, charging
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.
