Abstract
An internal combustion piston engine of the torch ignition type employs an auxiliary combustion chamber connected by a torch passage to a compact main combustion chamber. A spark plug has electrodes located adjacent the upstream end of the torch passage and remote from the intake valve for the auxiliary combustion chamber. At least one suction conduit intersects the torch passage between its ends and extends from a peripheral zone of the main combustion chamber. This zone may comprise a squish zone which increases flow of air-fuel mixture into the torch passage to follow the torch flame into the main combustion chamber. A cavity in the engine head may receive the torch flame from one or more torch passages.
