ABSTRACT:
An internal combustion piston engine has a main combustion chamber and an auxiliary combustion chamber connected by a torch passage. On the suction stroke of the piston lean mixture is drawn into the main combustion chamber and rich mixture is drawn into the auxiliary combustion chamber. A spark plug ignites the mixture in the auxiliary combustion chamber at the end of the compression stroke, causing a torch flame to be projected through the torch passage into the main combustion chamber near its center. A suction conduit, smaller in diameter and total area than the torch passage, extends from a peripheral portion of the main chamber and intersects the torch passage between its ends. Movement of the burning gases through the torch passage aspirates a flow of mixture from the main combustion chamber through the suction conduit into the torch passage.
