| Abstract:On the basis of flow, heat transfer, chemical reaction and turbulence combustion analysis ,the combustion simulation of GP210 lean-burn natural gas engine was conducted. The combustion simulation results were compared with the test results, which showed that the deviation was less than 5%, and indicated that the simulation was accurate and reliable. Analysis was carried out on the simulation results and the optimization direction of in-cylinder gas flow and combustion was suggested, which offered theoretical basis for efficiency improvement and emissions reduction. |
