Abstract

The utility model discloses a blade rotor engine, mainly comprising a stator, a rotor, an engine base, a bearing, an oil supply system and an ignition system. The blade rotor engine is characterized in that the inner surface of the stator comprises 4 cambered surfaces. Wherein, two of the cambered surfaces, the rotor and an output shaft are concentric circles, and the two of the cambered surfaces are divided into two unequal cavity chambers. The circumference of the rotor is provided with 4 deep slots and 4 shallow slots. Each deep slot is provided with 2 blades, and each shallow slot is provided with a radial sealing sheet. The end surface of the rotor is also provided with 2-3 sealing sheets. A spark plug is arranged on a sealing strip formed by the rotor and one cambered surface of the stator, so as to prevent gas mixture and fuel gas from mutually leaking. The oil supply system and the ignition system of the engine are similar with the oil supply system and the ignition system of the traditional reciprocating piston engine. As the capacities of the powering cavity chamber and the exhausting cavity chamber of the engine are larger than the capacities of the air-breathing cavity chamber and the compression cavity chamber, the blade rotor engine can prolong the intumescent period of the operating chamber and improve burning.
