Abstract

An oil injection system is provided for a two cycle crankcase compression internal combustion engine. A crankcase pressure driven oil pump (70) draws oil from an oil source (52, 54) and delivers pumped oil through an oil output line (64) to the fuel supply system. A solenoid valve (72) in the oil output line controls the flow of pumped oil to the fuel supply system.
