Abstract
A two-stroke engine including a combustion chamber formed in the cylinder head and having the fuel mixture introduced directly into the combustion chamber. A ventilation chamber surrounds the combustion chamber and opens directly into the combustion chamber and the cylinder, a flange on the head of the piston, progressively closing the opening into the combustion chamber as the piston approaches top dead center. The ventilation chamber may be formed as a plurality of individual chambers evenly distributed around the combustion chamber or as a recess opposite the outer periphery of the piston head. In the latter embodiment, an annular recess on the piston head, formed by the flange, adds to the volume of the ventilation chamber.
