ABSTRACT:
A by-pass connecting an induction passage and an intake manifold around a throttle valve is controlled by a by-pass valve which is operated by a pressure at a port opening to the induction passage just upstream of the closed throttle valve. During deceleration, atmospheric pressure is gradually applied to the port closing the by-pass valve.
