Abstract: The preparation of methanol can first use renewable energy such as solar energy to produce hydrogen, and then carbon dioxide can be converted into methanol fuel by hydrogenation. Therefore, using methanol as mixed fuel in traditional gasoline rotary engines can effectively reduce the carbon emission of rotary engines. In addition, turbulent jet ignition mode is considered to effectively improve the combustion rate of rotary engines. To deeply study the ignition and combustion process of a methanol/gasoline blends rotary engine using turbulent jet ignition mode, a three-dimensional simulation model and a performance test bench of the rotary engine were established in this paper, respectively. Further, using the experimental data, the reliability of the three-dimensional calculation model was verified. Based on the calculation model, the effects of ignition position and timing on the ignition and combustion process of the methanol/gasoline rotary engine using turbulent jet ignition mode were further studied. The results showed that the ignition position and the ignition timing could significantly change the ignition and combustion process in the cylinder by changing the impact timing between the jet flame and the rotor wall, the intensity of the jet flame and the position where the jet flame enters the cylinder.
