Abstract
An internal combustion engine is disclosed. The engine may have a cylinder that defines a combustion chamber for combusting an air/fuel mixture. The engine may also have a piston reciprocally movable within the cylinder between a top dead center (TDC) and a bottom dead center (BDC). The piston may have an uppermost piston ring configured to sealingly contact the cylinder. The engine may have an annular crevice facing the combustion chamber. The crevice may be defined by the cylinder, the piston, and the uppermost piston ring. The engine may also have a flow channel fluidly connected to the combustion chamber. The flow channel may direct unburned air/fuel-mixture out of the combustion chamber. The at least one flow channel may be fluidly connected to the annular crevice for a crank angle range of about 85° to 95° and about 265° to 275° after the top dead center (TDC).
