| Abstract: | A calculation of thermodynamic cycle and combustion of a high intensified DI diesel engine by CFD simulation tool FIRE is presented. The influence of swirl ratio and spray pressure on the combustion process in cylinders is analyzed. Finally, the matching of swirl ratio and spray pressure is simulated, which offers the theoretical foundation for the design of combustion system of small-bore diesel engines. |

| Keywords: | diesel engine swirl ratio spray pressure match numerical simulation |
