ABSTRACT:
An induction system for an internal combustion engine having at least one intake passage that is configured to generate a tumble and swirl to the intake charge. This is accomplished by providing a masked section adjacent the valve seat so that the flow entering the combustion chamber is directed across the combustion chamber to generate the tumble action. There is also provided a secondary intake passage that delivers a charge to the combustion chamber in a substantially unrestricted fashion so as to permit high power outputs. The secondary intake passage has the flow through it controlled by a throttle valve that is closed under low and mid-range running conditions.
