ABSTRACT:
A stratified-charge internal combustion engine (10) with fuel injection and dual ignition has a fuel injector (60) and two spark plugs (70) and (72) mounted in a cylinder head (16). The cylinder head (16) forms a combustion chamber (44) in conjunction with the cylinder (14) and piston (18). The spark plugs sequentially ignite the fuel plume (64, 66) emitted by the fuel injector simultaneously with the injection of the fuel. The piston (18) has a recess (80) that has its narrow portion in proximity to the injector and spark plug (70) and wider portion aligned under spark plug (72).
