Abstract

An oil injection system is provided for a two cycle crankcase compression internal combustion engine. A metering pump (74) draws oil from an oil tank (52) and controls the amount of oil supplied to the fuel supply system upstream of the fuel delivery device (24). The fuel supply system and the metering pump are both variably controlled by the fuel supply control (28).
