Performance of a manifold is researched by using CFD analysis software. First, this paper analyzes the uniformity of the intake manifold by calculating the flow rate of each pipe by using the certain pressure differential method; then, analyzes the performance of intake manifold by getting the pressure differential between the inlet and outlet by using the constant flow method; finally, makes comparison and validation through the test. The results show that optimized intake manifold is certainly better qualified in uniformity and liquidity.
