摘要
基于先进的EFS电控燃油系统测试台,并与台架两路油路电磁阀驱动模块配合,实现对非道路国三高压共轨系统的多次喷射的控制和精确测量。通过对比检测出了3批次国产燃油系统和1个批次量产装车的博世国三燃油系统,检验出国产燃油系统的生产一致性问题,得出了其结构改进方向。通过其小油量喷油实际较博世燃油系统偏大、大油量偏小的特点,得出燃油系统的油量补偿方式,并总结出了检验检测方式,由此得到对该国产燃油系统的控制、标定。为该系统成为无缝替代产品并批量匹配,提升柴油机相关产品的风险应对能力,提供了技术基础。
Based on the advanced EFS test bench for electric control fuel system, it was realized that the multiple injections volume of the non-road national three high-pressure common rail system was controlled and accurately measured in this paper, with two solenoid valve on the test bed.This paper compared 3 batches of domestic fuel system and 1 batch of Bosch Ⅲ fuel system, tested the production consistency of domestic fuel system and its structural improvement direction.And its small fuel injection was actually larger than Bosch system’s injection and vice versa.The compensation method of the volume of the fuel system was concluded, and the inspection and testing methods were summarized, as well as the control and calibration of the domestic fuel system.In this paper, the technical basis for the system to become a seamless replacement product and batch matching was provided, and it improved the risk response capability of the company’s diesel engine-related products.
