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

Abstract

The invention belongs to the field of internal combustion engines, and provides a stratified combustion type spark ignition type triangle rotor engine. The stratified combustion type spark ignition type triangle rotor engine comprises a cylinder body and a triangle rotor, the side surface of the cylinder body is provided with an oil nozzle and a glow plug in an inserting mode, the glow plug is located above the oil nozzle, the inner side wall of the cylinder body is provided with a precombustion chamber, and the end of the oil nozzle and the end of the glow plug are both located in the precombustion chamber; the triangle rotor is movably arranged in the cylinder body, an air feeding chamber, a compression chamber and an air exhausting chamber are formed between the triangle rotor and the inner wall of the cylinder body, the three side walls of the triangle rotor are provided with combustion chambers which are each of a tongue-shaped structure, one of the combustion chambers communicates with the compression chamber, and the compression chamber communicates with the precombustion chamber; and oil sprayed through the oil nozzle can be diffused into the precombustion chamber and the combustion chambers, and the oil in the precombustion chamber can ignite oil-liquid mixing gas in the combustion chambers after being combusted. Compared with the prior art, the stratified combustion type spark ignition type triangle rotor engine has the advantages that the ignition reliability and stability of the triangle rotor engine are improved.

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...
