Heat engine comprising two ring-shaped cylinders 1, 2 in each of which there is arranged a tubular piston 3a, 3b extending over a specific sector of a circle carried by a radial rod 4, 5, these rods being coupled by a coaxial shaft 6 which rotationally drives a driveshaft by means of a system of gears 8, ignition and injection means 9, 11, 35, 36 being provided in the rings 1, 2. This rotary piston engine operates without a crankshaft, its structure is simplified with respect to conventional engines. Application particularly to motor vehicles. <IMAGE>
