Abstract:
In view of that the pressure loss in the air inflow pipe caused by the resrtictor makes the actual fuel consumption relatively increaseing,the four-stroke engine of the formula SAE car is investigated here.The electronic fuel injection(EFI)system is analyzed from three aspects of the air-fuel ratio control of the mixed gas,the control of fuel injection quantity,and the measurement of air inflow.According to the characteristics of the EFI system,the air inflow correction scheme is designed,and the hardware and software of the control unit are accomplished.The test of pulse-width of EFI system shows that the control unit of air inflow correction can meet the design requirements,reduce the fuel consumption,and improve the competitiveness of the FSAE.
