Each cylinder has a piston axially reciprocal therein with the pistons in the two cylinders operating with a phase shift of 180.degree.. Each piston is connected by a piston rod to the same crankshaft located between the cylinders. Each piston moves between a bottom dead center at an inner end of the cylinder adjacent the crankshaft to a top dead center at an outer end of the cylinder spaced outwardly from the crankshaft. During movement of the piston from the inner end to the outer end, fresh air or a fuel-air mixture is drawn into the cylinder through a suction system and when the piston moves in the opposite direction a transfer system conveys the fresh air or fuel-air mixture into a combustion space formed between the outer end of the cylinder and the piston.

Abstract: In a two-stroke internal combustion piston engine, a piston is reciprocally movable within an axially elongated cylinder. The piston has a bottom dead center position and in the region of this position, the cylinder has an exhaust opening and a number of pairs of scavenging openings. An axially extending plane within the cylinder divides the exhaust opening in half and in each pair the scavenging openings are arranged symmetrically on opposite sides of the axially extending plane. Each pair of scavenging openings is located at a different distance from the exhaust opening. The projection of the side surfaces of the pairs of scavenging openings extending in the axial direction of the cylinder each form a different angle at the point of intersection of the projections and the point of intersection is directed away from the exhaust opening.
