The results show that the rail cavity volume has no effect on the fuel injection rate when the rail pressure fluctuation is slight and the size of inlet and outlet holes on the control couple has a great effect on the fuel injection rate. 试验结果表明:喷油规律在轨腔压力波动较小的前提下与其容积无关;控制室偶件进(出)量孔的大小对喷油规律有很大影响。
Study on Fuel Injection Control Strategy and Optimization of the Rail for High Pressure Common Rail 高压共轨喷油控制策略及共轨管优化设计研究
High pressure pump, which supply high pressure fuel to rail, is a main component of common rail system. High pressure pump would affect the performance of common rail system. 高压泵是高压共轨系统的重要组成部分,为高压共轨系统提供高压燃油,高压泵的好坏直接影响到高压共轨系统的性能。
The industrial control computer is the core of this system; the high-voltage signals in base cylinder ignition coil and the fluctuation signal in fuel rail are collected by data acquisition card, ignition signal sensor, oil pressure transmitter. 系统以工控机为核心,通过数据采集卡、点火信号传感器、油压变送器等,获取基准缸点火线圈高压信号和汽油分配管压力波动信号。
The common rail fuel injection system can be divided into the medium pressure common rail system and the high pressure common rail system. 共轨式喷油系统分为中压共轨系统和高压共轨系统。
