The FSCC competition limits the power output of the engine due to safety considerations for the participating players. All airflow entering the engine must flow through a 20 mm flow-limit valve (李理光 in 《中国大学生方程式汽车大赛规则》, 2020) [1]. In order to ensure the smooth power and torque output of engine under the restricted air intake rules, the engine air intake system needs to be redesigned. In this paper, a one-dimensional thermodynamic simulation model of the Triumph 675R engine was established and validated based on the calibration test data by GT-Power. On this basis, the length of the intake manifold and the volume of the plenum were optimized. Furthermore, a three-dimensional steady flow simulation of the redesigned intake system was carried out. The result shows that the total intake air mass flow rate of optimized intake system increases from 0.128 to 0.142 kg/s, and the intake imbalance reduces from 3.9 to 0.8%.
