| Abstract: | The 3D simulation of working process with KIVA-3V modified was achieved on standardization work condition of the 16V240ZJB engine. The paper analyzes the effect of swirl and turbulence kinetic energy on exhaust emission and combustion of diesel engine. The result shows that the swirl has effect on combustion of diesel engine. |
