ABSTRACT:
A piston for use in an internal combustion engine and including a central portion; a side wall portion adapted for sliding engagement with a cylinder; a connector end adapted for connection with a connecting rod; and a driven end adapted to receive combustion generated forces. The driven end defines a primary chamber adapted to receive fuel and accommodate combustion thereof; and the central body portion defines an auxiliary chamber, an inlet port providing a fuel injection path between the primary and auxiliary chambers, and outlet port means providing between the auxiliary and primary chambers a discharge path for combustion products generated by combustion in the auxiliary chamber.
