ABSTRACT:
In order to improve volumetric efficiency and to encourage swirling flow inside a combustion chamber of a reciprocating engine, an intake valve is provided having its stem located eccentrically with respect to the head of the valve. The valve stem guide bore in the cylinder head of the engine is correspondingly located to one side of the axis of the intake port and, preferably, toward the center of the combustion chamber. In addition, drive means are associated with the valve whereby it is oscillated about the axis of the stem so as to bias the flow area, upon opening movement of the valve, in a direction so as to direct an induction charge into the combustion chamber in a flow direction substantially tangential to the cylinder wall.
