ROTARY PISTON COMBUSTION ENGINE

摘要

A rotary piston combustion engine including a housing made up of a shell with multiarcuate inner surface and side parts. A polygonal piston is rotatably mounted on the eccentric of an eccentric shaft in the housing. The piston is provided with sealing parts to slide along the inner housing surfaces and to seal off adjacent working chambers from each other. Finally, means are provided for introducing a basic additive into the working chambers at least during the phase when the engine is running hot.
