Abstract
An internal combustion piston engine employs a stratified charge. Separate carburetor throats are provided for directing rich air-fuel mixture to a prechamber and lean air-fuel mixture to a main combustion chamber. The rich mixture is heated by the engine exhaust gases and then delivered to the prechamber. A spark plug ignites the rich mixture and causes a torch flame to project laterally through a torch slot in the prechamber wall into the main combustion chamber to ignite the lean mixture contained therein. In this way, the amount of unwanted emissions such as carbon monoxide may be reduced in the exhaust gases discharged into the atmosphere.
