摘要:
根据电控单体泵系统工作特点,完成控制单元软硬件设计。在油泵试验台上进行试验研究,结果表明:该控制单元性能稳定,电磁阀驱动响应迅速;在喷射过程中,喷射压力缓慢上升至峰值后急剧下降,实现了先缓后急的喷油规律;同一转速下,燃油喷射系统液力延迟时间基本相同,并且,随着转速上升而缩短

Abstract:
According to the working characteristics of the electronic unit pump system, the hardware and software of control unit were designed. Control test was carried out on the oil pump test bed. Results show that the performance of control unit is stable and reliable. Solenoid valve has a quicker dynamic response. Injection pressure declines sharply after rising up to peak slowly during the injecting process, which can achieve the boot type fuel injection law. The time of fuel injection delay is basically same in the same speed, and it will decrease with the increase of the speed.
