ABSTRACT:
A two stroke engine has a closed plane cylinder with an inlet port and outlet port disposed on opposite sides of the cylinder towards the open end thereof. A piston is slidingly sealed in the cylinder the piston having a head portion which is slidingly sealed with the wall of the cylinder and a connecting rod portion which extends axially from the head portion. The end of the connecting rod portion remote from the head portion is connected to a crank on a crankshaft, the ports being disposed one on each side of the vertical axial plane of the crankshaft so that; upon downward movement the piston will tilt, opening the exhaust port before the inlet port and; upon upward movement the piston will tilt closing the exhaust port before the inlet port, the throw of the crank producing a maximum piston tilt of up to 10.degree.. A multi-cylinder engine may comprise a plurality of piston/cylinder assemblies described above, disposed radially of one another about a common crankshaft.
