| Abstract: | The power and drive systems of a tracked vehicle engine are taken as subject.The idle deceleration process simulation of the engine is studied by using the CFD（Computational Fluid Dynamics）software and virtual prototyping software,and the deceleration process of the engine in different blow-by gas leak is stimulated,and it is validated by real-vehicle experiment.The foundation for judging technical state based on deceleration process of the engine is provided. |

| Keywords: | deceleration process blow-by gasleak equivalent cylinder pressure simulation |
