  • The liquidity and uniformity of intake manifold have a major impact on engine performance. A four-cylinder gasoline engine model was created by GT-power and the gas flow rate of intake manifold was simulated. Gas pressure and velocity distribution were showed in different inlet angles though STAR-CD and the intake uniformity and inflatable coefficient were analyzed in each of the branched pipe. The results show that the gas liquidity and the gas flow quality in branched pipe were improved by changing the air inlet direction and regulator chamber volume and other geometric parameters, which made the gas flow tended to be uniform in each pipe. The calculation results provide a theoretical basis for designing the intake manifold modified.
