ABSTRACT:
An induction system for a multi-valve internal combustion engine including a control valve arrangement for redirecting the flow into the combustion chamber through a relatively small displaced bypass passageway under certain running conditions so as to provide a high velocity flow into the combustion chamber even though the total air flow is small. The flow is also directed so as to generate a slant-type tumble motion in the combustion chamber to further increase the turbulence and improve combustion under the running conditions when the control valve is in its flow restricting flow redirecting position. The bypass passage has a relatively regular configuration with a low peripheral length to cross-sectional area ratio so as to provide a compact overall assembly and to facilitate manufacturing. In the open position, the control valve offers substantially no restriction to air flow so that high power outputs can be achieved while still maintaining good running under low-speed, low-load conditions.
