ABSTRACT:
Several embodiments of an induction system for internal combustion engines that improve volumetric efficiency and combustion efficiency throughout the engine speed and load ranges. In each embodiment, each chamber of the engine is provided with two intake valves and a spark plug that is symmetrically dispositioned in the chamber. The induction system includes auxiliary induction passages through which the major portion of the engine idle and low speed charge requirements are supplied. The auxiliary induction system is oriented so that the charge will be induced into the chambers at a high velocity and in a flow pattern so that the charge passes the spark plug at the time of ignition. In accordance with a further feature of the invention, a throttle valve is provided in the induction system, which throttle valve is rotatably supported in an insert that is interposed between the charge forming device and the engine chambers for controlling this flow.
