Engine induction system

摘要

An internal combustion engine has a tuned induction system with an air cleaner connected by a conduit with a separate plenum mounted on a manifold with individual runners connecting with the engine cylinders. A throttle body having a throttle to control induction air flow is located between the plenum and the manifold with its runner such that the plenum is not subject to reduced manifold pressures resulting from throttling the air flow.
