Patent ·
OSTI ID:6172750
An internal combustion piston engine has a main combustion chamber supplied with a lean mixture and auxiliary combustion chamber supplied with a rich mixrue. A spark plug ignites a mixture in the auxiliary chamber to project a flame through a torch passage into the main chamber. Walls in the underside of the stationary head of the engine form a flame guide channel diverging from the torch passage toward intake and exhaust valves which are located equidistantly from the torch passage. The torch passage may comprise an elongated slot or a pair of spaced openings.
