Two stroke engine - has crankshaft turning on planet gear to give compression and power strokes

摘要

The two stroke engine crankshaft runs in a planet gear and the piston consists of a disc with a piston ring and screwed onto a solid or tubular connecting rod. The cylinder at the lower end has openings regulated by the piston movement to suck in pure air via one way valves as the piston rises and compress the air into the crankcase as the piston descends. A transfer channel is cast in the engine block to enable to crankcase air to enter the combustion chamber. A labyrinth seal is provided between the crankcase and the cylinder base which allows an alternating depression and compression in a pre compression chamber to occur without drawing oil from the bearings.
