Abstract: The 1-D cooling system simulation model of the engine is built basing on arrangement principle of the cooling system of an engine, obtaining boundary limits of the inlet and outlet of the water jacket. The data is used on CFD analysis and the evaluation is done to cooling ability in some key points of the cooling jacket. At last, we can propose the improvement plans and give a CFD analysis to the improved structure.
