Abstract：Taking FSAE formula racing CBR600 engine as the research objective and based onthe theory of hydrodynamics,by analyzing the cause and location of the energy loss of the engine intake air,the relevant structural parameters of the intake system were initially set.The two-dimensional model of the racing engine was established by GT-Power software,simulation analysis was conducted to determine the optimum value of intake pipe length as 300 mm and the best regulator cavity volume as 3.5 L.The model of the air intake system was established by Catia.The Fluent software was used to simulate the flow field of the intake system and the elliptical cylider regulator cavity could be obtained by comparing the pressure and velocity diagrams.The experimental results showed that the air intake system could meet the needs of the CBR600 engine and improve the air intake performance by about 5％ to 10％.
