ABSTRACT:
A torch ignition type internal combustion engine has a trap chamber comprising a cup-shaped member of a heat-resistant metal mounted on a cylinder head of the engine. The member has a substantially closed end protruding into a main combustion chamber and suction and discharge apertures through which the trap chamber always communicates with the main combustion chamber. A single intake port is provided in the cylinder head for supplying air-fuel mixture charges to both the main combustion chamber and trap chamber. The suction aperture is positioned adjacent to the back face of the valve head when it is in the open position so that a part of the air-fuel mixture from the single intake port flowing over the back face of the valve head is introduced through the suction aperture into the trap chamber on the intake stroke and ignited on the combustion stroke by a spark plug to provide torch jets which run through the suction and discharge apertures into the main combustion chamber, whereby a torch-ignition of the air-fuel mixture in the main combustion chamber is achieved by a simplified engine construction.
