ABSTRACT:
A rotary piston internal combustion engine of trochoidal construction which operates with ignition of fuel-air mixture by spark plugs and which is equipped with a polygonal piston, for example, a triangular piston rotatably supported on the eccentric of an eccentric shaft. The piston slides with its corners along the trochoidal running surface, for example, along a two-arched trochoidally shaped running surface while a piston flank is disposed between each two corners of the piston, to which is coordinated a working chamber within the housing. The casing is also provided with an inlet channel having a throttling member arranged therein and with an exhaust channel. An arrangement is provided which in dependence on the number of stages of the engine and with a closed and substantially closed throttling device prevent, after an ignition of the fuel-air mixture in a working chamber, at least once an ignition of the fuel-air mixture in the same working chamber for purposes of achieving a high uniformity and/or small periodic length of the torque at the eccentric shaft by the suppression of the ignition pulse.
