ABSTRACT:
A novel combustion chamber configuration locates the stems of all four of its valves in a parallel with the axis of the engine cylinder closed by the chamber. In this variation which is especially well suited for a barrel-stratified mode of engine operation, the spark plug can readily be offset a moderate distance from the axis of the cylinder into the fueled side of the combustion chamber because the pair of intake valves is separated from the pair of exhaust valves by an extra amount. The associated overlapping of the intake valve faces outside of a projection of the cylinder bore is utilized to form two symmetric flow masks which in turn function as the primary means for generating strong barrel swirl during the intake stroke.
