Abstract
A fuel supply system for a two cycle crankcase compression internal combustion engine embodying direct cylinder injection and carburetors for supplying a fuel air mixture to the crankcase chambers of the engine for high speed cooling. The direct fuel injectors supply the fuel at the low speed operation and a fixed amount of fuel at mid range and high speed, while the carburetor supplies only the mid range and high speed requirements of the engine in combination with the fuel injectors. Fuel is supplied first to the fuel bowls of the carburetors which have a vapor vent and then from the fuel bowls to the fuel injectors so as to avoid the necessity of a separate vapor separator for the fuel injectors.
