Power Improvement and Vehicle Matching of Racing Engine Based on FSC

After the University formula auto race was introduced into China in 2009, it quickly became an innovative practice activity for college students that many college students are willing to participate in. Due to the restrictions of the competition rules, FSC racing cars use engines with a displacement of less than 710 cc and need to pass through a 20 mm flow limiting valve (1). Firstly, this paper uses MOTEC M800 to calibrate and match various sensors. Secondly, on the bench test, the engine ignition, fuel injection map and the auxiliary correction of environmental parameters to the ignition advance angle and fuel injection pulse width are carried out, so as to achieve the maximum power of the engine under the rule limit. Finally, in order to improve the driver's operability and combine the characteristics of the track, the traction control and launching control functions are introduced. The launching control and traction control are determined through the running state of the whole vehicle, the driver's feedback and I2 data. Make the power system of the whole vehicle have strong competition.
