ABSTRACT:
An internal combustion engine has a main combustion chamber and an auxiliary combustion chamber associated with each piston and connected by a torch opening. A lean mixture is supplied to the main combustion chamber and a rich mixture is supplied to the auxiliary combustion chamber. After compression, ignition of the mixture in the auxiliary combustion chamber projects a flame through the torch opening to burn the lean mixture in the main combustion chamber. In order to prevent an over-rich mixture developing in the auxiliary combustion chamber upon rapid acceleration of the engine, correction devices and systems are employed to reduce the ratio of air intakes or to supply secondary air during such rapid acceleration. Such correction systems and devices may be rendered inoperative during initial startup of the engine.
