Abstract
An induction system for an internal combustion engine having a relatively large main intake passage that supplies the cylinders under medium and high load conditions and a relatively small auxiliary induction passage that feeds the cylinders under idle and low load conditions. The flow through the induction passages is controlled by a main and an auxiliary throttle valve which are interconnected by a linkage system that improves induction efficiency throughout the engine speed and load ranges.
