The traditional approach to limiting the maximum output power of a FSAE car’s engine is to install a single circular restrictor at the engine. However, restrictor installation would adversely lower the air flow speed and fuel burning rate, which further result in the declining of the pressure in the intake pipe. In this paper, we first analyze the influence of intake restrictor on engine power, intake pipe’s pressure, inflatable efficiency and fuel consumption in the case of a typical four-stroke engine of FSAE cars. One-dimensional engine cycles are simulated by using the AVL BOOST. Intake quantity correction is then designed based on the characteristics of EFI system and the analysis results. The control unit is further designed by both means of hardware circuit and software design. According to pulse width of driving signal for injecting fuel, the performance of FSAE car’s engine is improved by intake quantity correction of the control unit. Other direct improvement includes lowered fuel consumption hence more economical efficiency.
