Abstract
An induction system for an internal combustion engine for improving running throughout the entire engine speed and load ranges. The induction system comprises a first intake passage that serves the chamber through a first intake port and a second intake passage that serves the chamber through second and third intake ports. The effective cross-sectional area of the first intake passage is substantially smaller than that of the second intake passage and staged throttle valves are incorporated so that the charge requirements at low speed are supplied primarily through the first intake passage.
