ABSTRACT:
A four-stroke internal combustion piston engine includes at least two cylinders disposed in axial alignment opposite on another. 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. Each cylinder has its own suction system and transfer system including check valves so that the supply and flow of the fresh air or fuel-air mixture is separate for each cylinder.
