| Abstract: | The change laws of flow coefficient and swirl ratio of the inlet port of a diesel engine with the lift of its intake valve are analyzed, and the influence of the gap of air pressure between the front and back of the inlet on flow coefficient and swirl ratio is also discussed. The experimental results show this intake system of diesel engine can realize high swirl ratio at low load, thus improves the performance of the diesel engine. |

| Keywords: | diesel engine inlet port flow coefficient swirl ratio |
