Abstract
An internal combustion engine is provided with an auxiliary piston reciprocating within an auxiliary chamber for generating turbulence in a gas mixture contained within a main combustion chamber. Forward motion of the auxiliary piston causes the injection of a gas into the main combustion chamber through a communicating passageway when the main piston approaches top dead center of the compression stroke.
