Abstract
An improved induction system for a V type engine that is tuned for substantially all running conditions and which is nevertheless compact in construction. The system includes a pair of plenum chambers each disposed adjacent one of the cylinder heads of the engine. Each cylinder head has at least two intake passages serving the respective cylinder bores and a first conduit extends from the adjacent plenum chamber to one of the intake passages and a second conduit extends from the other of the plenum chambers to the other intake passage. The plenum chambers communicate with each other at their opposite ends to improve air flow and a common inlet opening serves each plenum chamber inlet. A throttle valve arrangement is also incorporated so that good performance is achieved under all running conditions.
