维修注意事项

高压共轨系统的维修
系统对低压油路有非常高的要求,从油箱 到泵箱过程中包括油水分离器和输油泵。其中油 水分离器的保养行程大概在12000Km左右,属 于消耗品。现国内大部分的燃油不能保证清洁度 ,达不到欧三燃油标准,非常容易导致油水分离 器堵塞,严重的情况下可能会出现输油泵的工作 能力下降和油泵柱塞卡死的故障。系统要求油水 分离器30μm、精滤5μm,再保养过程中不可用 常规滤清器代替。

柴油机功率不足

高压共轨系统的维修
功率限制:发动机带故障运行的一种模式。 ECU检测到发动机出现了故障,但不会立 即停车,而是会限制发动机的功率,使发 动机转速只能增加到1500转,司机能将车 开到就近的维修站进行维修。

柴油机功率不足

高压共轨系统的维修
功率限制的原因: 1:水温过高; 2:机油温过高; 3:进气温度过高; 水温、机油温、进气温度过高时,ECU 会进入过热保护功能,限制发动机功率。

柴油机功率不足

高压共轨系统的维修
燃油计量单元是控制轨压的执行器, 安装在高压油泵上,出现问题以后,高压 油泵会以最大的能力向共轨管供油,此时 共轨管上的泄压阀将会打开,柴油机会有 “咔咔”的噪音。轨压传感器出现问题也 会有类似的现象。
