ABSTRACT:
An induction system for an internal combustion engine that is provided with a relatively small auxiliary intake passage that delivers the intake charge to the combustion chamber at a high velocity and high degree of turbulence. Throttle valve means are provided for directing a substantial portion of the idle and low-speed intake into the chamber through this auxiliary intake passage so as to improve flame propagation and engine performance under these running conditions. The intake for the auxiliary induction passage is disposed so that it will be exposed to atmospheric pressure under at least some low-speed running characteristics so as to improve the amount of charge drawn through the auxiliary induction passage during these conditions.
