ABSTRACT:
A two stroke cycle internal combustion engine (10) is provided which has a one-piece cylinder housing (14) removably secured to a valve drive housing (12) at a top section thereof and a crank housing (16) at a bottom section. The overall combination of the valve drive housing (12), the cylinder housing (14) and the crank housing (16) are formed in a substantially symmetrical manner about a vertical axis line (18). An intake valve member (30) is positioned in a top section of cylinder housing (14) with an exhaust port (62) located at the bottom of a piston (44) travel within a combustion chamber (54). The valve member (30) opens on a downward stroke of the piston (44) which feeds compressed air into chamber (54) and forces spent gases through the exhaust port (62).
