Rotor engine

Abstract

The invention provides a rotor engine, belongs to the technical field of engines, and solves such technical problems as bad wear and difficult sealing of a traditional rotor engine. The rotor engine comprises a cylinder, and rotors positioned in the cylinder; the rotors divide the cylinder into three combustion chambers; the rotors include main bodies, and sealing parts respectively positioned at three corners of the main bodies; multiple sealing steel rings are arranged on the inner wall of the cylinder; rotating columns capable of freely rotating are arranged at the sealing parts, and are provided with sealing modules corresponding to the sealing steel rings one to one; the main bodies are provided with hydraulic cavities corresponding to the rotating columns one to one; the main bodies are provided with pressure synchronizing devices capable of keeping synchronization between the pressures in the hydraulic cavities and the higher pressure of the pressures in the two combustion chambers on two sides of seals; and the sealing parts can be pressed with the inner wall of the cylinder under the effect of the pressures in the hydraulic cavities. The rotor engine has such advantages as low wear and excellent sealing.

Description

technical field [0001] The invention belongs to the technical field of engines, and relates to an engine, in particular to a rotary engine. Background technique [0002] The rotor of the rotary engine does work three times every time it rotates. Compared with the general four-stroke engine, which only works once every two circles, it has the advantage of high horsepower volume ratio (the engine volume is small and can output more power). Additionally, due to the axial nature of the rotary engine, it does not require precise crankshaft balancing to achieve high operating speeds. The whole engine has only two rotating parts, which is greatly simplified in structure compared with more than 20 moving parts such as intake and exhaust valves in general four-stroke engines, and the possibility of failure is also greatly reduced. In addition to the above advantages, the advantages of the rotary engine also include smaller size, light weight, low center of gravity, and less vibratio...

AI Technical Summary

Problems solved by technology

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
