ABSTRACT:
An internal combustion piston engine has a main combustion chamber and an auxiliary combustion chamber connected by a torch passage, which is cylindrical end to end. Lean mixture is supplied to the main combustion chamber and rich mixture is supplied to the auxiliary combustion chamber. A spark plug ignites the mixture in the auxiliary combustion chamber, causing a torch flame to be projected through the torch passage into the main combustion chamber near its center. Suction conduits, smaller in diameter and total area than the torch passage, extend from a peripheral portion of the main chamber and intersect 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 conduits into the torch passage.
