font-size: 15px; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif;">这套燃油系统的结构是油箱内的低压油泵将燃油泵出送到高压油泵提高压力以后，在适当的喷油时刻喷入气缸，多余的燃油会回流到油箱。低压油泵是由燃油泵控制单元控制的，燃油泵控制单元通过改变低压油泵的电流大小来改变油泵转速，从而调节低压燃油压力，低压燃油压力通常在3-7BAR的范围内（根据车型有所差异）。</span></section><section style="box-sizing: border-box;

font-size: 15px; font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif;">高压油泵由凸轮轴尾部的凸轮驱动，发动机电脑通过控制高压泵上的油压调节电磁阀来改变高压泵的回油量，从而实现了对高压油压的调节。在高压油轨上有一个高压油压传感器，该传感器测量高压油轨的压力并把信号提供给发动机电脑，发动机电脑根据高压油轨的实际压力与经过计算得出的油压期望值之间的偏差来对油压进行实时调节，怠速时的高压压力一般都在30BAR以上。</span></section></section><section style="box-sizing: border-box;
