In order to analyze the internal flow of the rotary impeller internal combustion engine, the exhaust, intake and compression process were numerically simulated at rated speed, and the impact of the intake parameters on the cold flow field was also studied. Through the analysis of the working process of the rotary impeller internal combustion engine, it has been found that there is the swirling flow in the combustion chamber in the process of intake and exhaust, gas movement is complicated, and the average pressure decreases first and then increases. In the compression process, the average pressure of the combustion chamber gradually increases, and the gas flow is stable. For the intake angle, when the intake angle is 0 °, it is advantageous to carry out the exhaust. The greater the intake temperature and pressure, the more complex the gas movement in the combustion chamber.
