| Abstract: | To study the process of intake and compression stroke of diesel engine with internal EGR, three - dimensional transient flow numerical simulation was performed using the universal CFD software STAR- CD and ES - ICE. The stratification of O2 component of the mixed gas and the temperature in cylinder was studied. The effect of internal EGR on cylinder temperature and concentration field are obtained, which established the foundation for further research. |
