Abstract:
A rotary piston internal combustion engine comprising:a housing; at least one working wheel mounted rotatably about an axis of rotation in the housing; at least one working piston provided on the working wheel for taking in and compressing air or a fuel-air mixture and for converting the gas pressure resulting from combustion of a fuel-air mixture into mechanical energy; at least one counter wheel with at least one working piston recess; at least one combustion chamber for combusting a fuel-air mixture, wherein the at least one combustion chamber in operation is formed continuously anew between the at least one working piston, the at least one working wheel, the at least one counter wheel, and the housing; a number of first air vanes driveable in rotation for pre-compression of air or of a fuel-air mixture, wherein the first air vanes, in the form of spokes, are a part of the at least one working wheel and in operation take in the fuel-air mixture or the air through the working wheel; wherein the at least one working wheel is pulley-shaped and comprises at least one annular channel extending peripherally on the at least one working wheel in a circumferential direction and being interrupted by the at least one working piston; wherein the at least one working piston is arranged fixedly in the at least one annular channel.
