| Abstract: | On the basis of analysis and calculation, and combined with CFD calculation, the inner pressure of the exhaust manifold as well as the distribution of speed were simulated and analyzed. Based on the analysis results, optitnization was carried out on the design of the exhaust manifold. Through the test of the engine per- formance, the best structure was determined which had satisfying results and achieved expected target. |
