ABSTRACT OF DISCLOSURE Disclosed herein is an internal combustion engine comprising a combustion chamber, a crankcase, a piston movable relative to the combustion chamber and the crank- case to effect cyclical pressure variation in the crankcase in response to piston movement, a transfer passage for intro- ducing fuel-air mixture into the combustion chamber from the crankcase in response to cyclical crankcase pressure varia- tion, an auxiliary chamber separate from the transfer passage, and a port arrangement for providing the auxiliary chamber with pressurized air in response to cyclical crankcase pressure variation and for initiating communication of the auxiliary chamber with the combustion chamber in response to piston move- ment during the presence of pressurized air in the auxiliary chamber and at a time other than the time of initiation of introduction of fuel-air mixture into the combustion chamber. Also disclosed herein is a method of operating the internal combustion engine comprising the steps of supplying a fuel-air mixture to the crankcase during a condition of relatively low pressure in the crankcase, introducing air into the auxiliary chamber in response to establishing communica- tion between the auxiliary chamber and the crankcase during a condition of relatively low pressure in the crankcase, there- after pressurizing the air in the auxiliary chamber in response to establishing communication between the auxiliary chamber and crankcase during a condition of relatively high pressure in the crankcase, introducing the fuel-air mixture into the cylinder from the crankcase by establishing communication between the transfer passage and the cylinder during a condi- tion of relatively high pressure in the crankcase, and intro- ducing the pressurized air into the cylinder from the auxiliary (Abstract of Disclosure cont'd) chamber by establishing communication between the auxiliary chamber and the cylinder such that communication between the cylinder and the auxiliary chamber is initiated at a time other than the time of initiation of introduction of fuel-air mixture into the cylinder.
