Description
The application is a divisional application entitled rotor engine and a method for regulating and controlling operating parameters thereof, wherein the application number of a parent application is 202010920945.0, and the application date is 2020.09.04.

Background
The rotor engine adopts the rotary motion of a rotor in a cylinder body to control compression and discharge, and is different from the traditional reciprocating piston engine, and the linear reciprocating motion is changed into the rotary motion. Compared with reciprocating engines, the rotary engine cancels useless linear motion, so that the rotary engine with the same power has smaller size, lighter weight and lower vibration and noise, and becomes a novel and efficient engine technology in the field of automobile industry. A relatively representative rotary engine technology is a triangular rotary engine of mayoda, for example, a rotary piston engine disclosed in publication No. CN101413436 and a design method thereof, in which a rotary part orbits an output shaft and rotates about an eccentric shaft that is parallel to the output shaft and offset, and the rotor is approximately triangular when viewed from the axial direction. The rotor engine with the structure has high oil consumption and small compression, so that only a compression ignition type combustion mode can be used, and the types of fuels are limited.
The rotor of the rotor engine rotates in the shell around the rotating shaft, and along with the rotation, the space enclosed by the outer side wall of the rotor and the inner wall of the shell is also continuously changed, so that oil and gas are mixed and combusted to do work. Taking a piston engine as an example, the motion of a piston brings the change of a closed space in the engine, the ratio of the maximum volume to the minimum volume in the whole piston motion stroke is the compression ratio, and the higher the compression ratio of the engine is, the better the performance of the engine is represented.
