Description

technical field [0001] The invention belongs to the field of internal combustion engines, and in particular relates to a stratified combustion ignition type triangular rotor engine. Background technique [0002] Triangular rotor engine, also known as Wankel engine, is a rotary piston four-stroke engine, which is characterized in that the three vertices of the triangular rotor are close to the inner wall of the triangular rotor engine cylinder, and the triangular rotor revolves around the eccentric shaft. It also rotates around itself and performs planetary motion through gear meshing. The ratio of triangular rotor speed to eccentric shaft speed is 1:3. When the triangular rotor engine is working, with the planetary motion of the triangular rotor, the mixture is rotated and compressed, and the volume reaches the minimum value at the top dead center of the compression stage. During the compression process, the compressed mixture is ignited at the proper ignition time, and th...

AI Technical Summary

Problems solved by technology

[0003] One of the main problems of the triangular rotor engine is poor combustion stability and insufficient combustion. The main reason is that the combustion chamber of the triangular rotor engine is flat and the combustion path is long and narrow. During the compression stage, a large horizontal airflow will be generated in the combustion chamber, which is easy to blow out. Flames are not conducive to reliable ignition and stable combustion of the mixture, affecting the combustion reliability of the triangular rotor engine, resulting in high fuel consumption and poor emissions, which need to be improved
