ABSTRACT:
An intake and exhaust pipe construction for an internal combustion engine of the type having a main combustion chamber supplied with a lean mixture and an auxiliary combustion chamber supplied with a rich mixture. A spark plug ignites the rich mixture in the auxiliary chamber and the resulting torch flame passes through a torch nozzle to ignite the lean mixture in the main chamber. The auxiliary intake passage which supplies the auxiliary combustion chamber with the rich air fuel mixture is integrally formed with the exhaust passage such that a common wall extends there between. A shell is disposed about the intake and exhaust passages and spaced therefrom to form an air gap between the shell and passages. Openings are provided in the shell for allowing air flow to and from the air gap. The air flowing from the gap is directed by a conduit to the inlet opening of the intake system.
