Design and analysis of air intake system based on formula student racing car

Abstract

Wuhan University of Technology FSC racing car adopts CBR600 four-cylinder engine, which is the decisive factor body of racing power. Considering the Rules of China Formula Student Car Competition (2021), the air intake system shall be composed of air filter, throttle, restrictor valve, pressure stabilizer and injection base. The intake system is particularly important to the analysis of engine power performance and stability, especially the pressure stable box through the simulation optimization of the intake pressure stable box, can increase the intake flow and reduce the intake uneven degree, so that the comprehensive performance of the intake system improved by 34%。
