摘要:
针对限制器引起的进气管内压力损失会增加赛车实际油耗的问题,该文以单缸四冲程赛车发动机为研究对象,从混合气体空燃比控制、喷油量的控制和进气量测量3个方面分析了电喷系统,结合电喷系统的特点建立了进气量修正方案,在此基础进行了控制单元的硬件和软件设计。通过对发动机喷油脉宽的检测验证了进气量修正控制单元满足设计要求,达到了降低油耗、提高赛车竞争力的目的。
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.
