| Abstract: | Calculating heat release rate of combustion through the actual indicator diagrams,then according to testing the influence of combustion process of TBD620 Diesel Engine which affected by intake swirl,and we obtain the data.We can get that under part load operation condition,closing the inlet swirl baffle can improve inlet swirl ratio,and effectively improve the quality of inflammable mixture formation and shorten the ignition delay time and increase the proportion of premixed combustion. |

| Keywords: | diesel engine part load inlet swirl control heat release rate |
