Abstract
An internal combustion engine having a main combustion chamber and an auxiliary combustion chamber connected by a torch opening has a first carburetor for supplying a lean mixture to the main combustion chamber and a second carburetor for supplying a rich mixture to the auxiliary combustion chamber. A turbo supercharger is operatively positioned between the first carburetor and the main combustion chamber. When the engine is operating under low load, the lean mixture is bypassed around the supercharger. When the engine is operating under high load, all of the lean mixture passes through the supercharger and a second bypass is opened so that the supercharged lean mixture is delivered to both combustion chambers.
