ABSTRACT:
An induction system for an internal combustion engine that improves mid range torque without sacrificing low speed running or high speed performance. Each cylinder of the engine is served by two intake ports that are, in turn, served by respective intake passages that have a common portion. A first throttle valve is positioned in the common portion for precluding the back flow of exhaust gases and for controlling the flow to the chamber. In addition, first and second inlet passages discharge into the common intake passage and a throttle valve is positioned in one of those inlet passages.
