Novel rotary engine

Abstract

The invention discloses a novel rotary engine which comprises an engine casing, rotating vane shafts, rotating vanes, a main shaft and a rotor, where an air inlet, an exhaust opening and a spark plug are arranged on the engine casing; the two ends of the cylindrical engine casing are closed by end covers; rails are mounted on the inner walls of the end covers; the rotor and the main shaft are coaxially arranged in the engine casing; a plurality of rotating vane grooves are uniformly formed in the rotor in the radial direction; the rotating vane shafts and rotating vanes are mounted in the rotating vane grooves in a sliding manner; the two sides of the rotating vane shafts are embedded in the rails and matched with the rails in a sliding manner. The novel rotary engine has the advantages that the technical difficulties of the quick wear and poor sealing property of the sealing fins of the traditional rotary engine are overcome; the rotating vane shafts are supported in the rails of the end covers, so the rotor is enabled to slide along the track, and the excessive wear of the sealing fins is avoided; in addition, due to sealing rings embedded in sealing grooves, the sealing property of the cavity of the engine is improved; the novel rotary engine has the characteristics of small size, good sealing property, high compression ratio and low cost, and has excellent practicability.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a novel rotary engine. Background technique [0002] At present, the triangular rotor engine has entered the practical stage. Although the triangular rotor engine has some characteristics of both the reciprocating engine and the gas turbine, since there is only one radial sealing piece between the adjacent chambers of the triangular rotor engine, the radial sealing piece is always in line contact with the cylinder body, and the radial sealing The contact position of the sheet with the cylinder block is always changing, so the three combustion chambers are not completely isolated, and the radial sealing sheet wears quickly. After the engine has been used for a period of time, it is easy to cause air leakage due to the wear of the oil seal material, which greatly increases fuel consumption and pollution. Its unique mechanical structure also makes this type of engine more difficul...

Although the triangular rotor engine has some characteristics of both the reciprocating engine and the gas turbine, since there is only one radial sealing piece between the adjacent chambers of the triangular rotor engine, the radial sealing piece is always in line contact with the cylinder body, and the radial sealing The contact position of the plate with the cylinder block is always changing, so the three combustion chambers are not completely isolated, and the radial sealing plate wears quickly

After the engine has been used for a period of time, it is easy to cause air leakage due to the wear of the oil seal material, which greatly increases fuel consumption and pollution

Its unique mechanical structure also makes this type of engine more difficult to repair
