- 燃油油位
- 直接齿条油门信号(仅石油发动机)
- 燃油供应压力
- 燃油压力调节器(客户安装的部件)
- 增压泵(客户安装的部件)
肉眼检查燃油箱中的燃油油位。 确保燃油箱含有足够的燃油供发动机工作。
来自外部调速器的直接齿条信号丢失可导致发动机停机。 将记录一个 91-8 油门位置传感器:频率、脉冲宽度或周期异常诊断代码。 请参阅故障诊断与排除, "直接燃油控制模式 - 测试"。

供油压力是在压力端口 (A) 测量。 输油泵进口的最小燃油压力为
检查燃油箱通气口上有无碎屑。 清除所有阻塞压缩空气的杂物。
注: 清洁盖时不要让碎屑进入燃油箱。 否则可能会损坏燃油系统。
检查燃油管有无损坏。 燃油供油管中的阻塞会限制燃油在燃油供应回路中的流动。 更换损坏的管路。
检查燃油箱上的增压泵与燃油粗滤器进口之间有无燃油压力调节器。
如果存在调节器,则检查调节器出口处的燃油压力。 如果燃油压力不在技术规格范围内,则调整调节器。 如果怀疑调节器存在故障,则更换燃油压力调节器。
检查增压泵出口处的燃油压力。
如果增压泵的出口压力不在技术规格范围内,则检查增压泵有无故障。 如果发现增压泵存在故障,则修理或更换泵。
