ABSTRACT:
Several embodiments of induction systems for internal combustion engines wherein a first, relatively long intake passage and a second, relatively short intake passage, serve each combustion chamber. A throttle valve arrangement is incorporated so that the shorter intake passages only serve the combustion chamber at high speed for high speed tuning. Each of the intake passages receives its charge from respective plenum chamber and there is only one air inlet device for delivering atmospheric air to one of the plenum chambers. The other plenum chamber is charged from the first plenum chamber either through a direct conduit or through the shorter intake passages.
