ABSTRACT:
Disclosed herein is apparatus including all of the components present in a conventional internal combustion engine such as body forming cylinder walls that define a primary combustion chamber, a piston reciprocable in the cylinder between compression and power strokes, intake means for introducing fuel charges into the primary combustion chamber, ignition means for igniting fuel charges and exhaust means for removing residual gases from the primary chamber after ignition of each fuel charge. Added to these conventional engine components is a housing that defines an auxiliary combustion chamber and an orifice that provides communication between the primary and auxiliary combustion chambers. During operation of the engine, both the primary and auxiliary chambers are charged with a fuel mixture after which the charge in the auxiliary chamber is ignited producing a jet of turbulent flame that passes through the orifice into the primary chamber inducing complete and uniform mixing and burning of the fuel mixture retained thereby. Optimum performance of the engine is insured by a purging mechanism that moves through the auxiliary combustion chamber after each ignition cycle so as to force residual gases out of the orifice which therefore functions also as an exhaust port. This purging provides a free volume for receiving an undiluted fresh fuel charge.
