ABSTRACT:
An induction system for an internal combustion engine that has, in addition to the conventional main intake passage, a relatively small cross-sectional auxiliary intake passage which discharges into the main intake passage upstream of the point of communication of the main intake passage with the engine chamber and downstream of the throttle valve of the engine. A relatively large capacity plenum chamber feeds the auxiliary intake passage so that on the intake cycle a high velocity charge will be delivered from the auxiliary intake passage into the chamber to increase turbulence and improve the combustion efficiency.
