  • Intake means of internal combustion engine
    Patent number: 4702203
    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 air boxes 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 air box to one of the intake passages and a second conduit extends from the other of the air boxes to the other intake passage. A throttle valve arrangement is also incorporated so that good performance is achieved under all running conditions.
