摘　　要：为了提高节能赛车在本田(Honda)中国节能竞技大赛中的燃油经济性,采用PGM-FI电喷系统.由于该系统在节能车上无法直接安装,设计了一套喷油压力调节系统,使其在保证供油系统稳定性的同时,能可靠地工作.同时,建立基于AMESim仿真软件的燃油喷射系统模型,在不同工作频率下对喷油压力进行仿真.结果显示,喷油系统的稳定性得到了提高,通过实车比赛验证,节能车燃油经济性提高了6.9%.A PGM-FI fuel injection system was adopted in order to improve the fuel economy of cars in Honda Eco Mileage Challenge. For the problem that the system can not be installed directly in fuel- efficient vehicle, a fuel injection system with adjustable pressure designed, which can improve the stability of fuel injection. A fuel injection system model by AMESim simulation software was established, and the injection pressure were simulated under different operating frequencies. The simulation result shows that the stability of fuel injection system can be improved. The demonstration in real road challenge reflects that fuel economy of the car can be improved by 6.9 %.
