水在芯子的管内流动，油在芯子与外壳的夹层间流动。柴油发电机旁通阀和限压阀在通常情况下不必解体维修，但若旁通阀内部的球阀与阀座出现磨耗、限压弹簧弹力减弱或折断时，应拆除后进行检查。球阀与阀座的磨耗较轻时，可在球阀与阀座之间涂上研磨音进行对磨；损伤较时，可镜削或磨削座面，然后更换或磨削阀面。球阀可用直径相同的钢球代替。
喷油器是柴油发电机燃油喷射系统的部分，其技术状况对发电机性能的正常发挥影响较大。由于喷油器工作环境，直接暴露在高温高压的燃烧室中，喷孔处的油膜容易发生氧化、聚合等系列反应，生成积碳在喷孔处，现有研究发现，喷油器喷孔积碳后会导致喷油流量损失增大、雾化和燃烧质量变差、发电机动力性和经济性下降等问题。
当柴油发电机工作中出现了不规则的敲缸声、间断冒黑烟、运转不平稳、功率下降、启动困难，说明喷油器
可能出现了故障，如针阀与针阀体的密封锥面磨损、针阀和针阀体导向圆柱曲磨损、针阀雾化锥体磨损等。当喷油器喷孔因柴油不洁净面堵塞时，表现为喷孔直径变细和喷注形状及喷射方向发生改变，时无燃油喷出。
如何正确的对柴油发电机的喷油器进行拆卸
喷油器体的拆卸。从柴油发电机上拆下喷油器，放入油盆中清洗干净。对轴针式喷油器因轴针伸在喷油嘴外面，应注意不要碰坏轴针头部。将喷油器夹在装有铜钳口的工作台钳上，旋下喷油器紧帽，清除喷油嘴偶件
外部积碳，取出喷油嘴偶件，然后将喷油器紧帽旋入喷油器体，以保护喷油器体下端研磨平面。将喷油器体从台钳上卸下，倒转180°，再夹到工作台钳上。拆下喷油器体上的护帽、调压螺钉、调压弹簧、顶杆。
喷油嘴偶件的拆卸。将喷油嘴偶件放在洁净的柴油中清洗油污，并从喷油嘴偶件中抽出针阀。当针阀被咬住不易拔出时，可在汽油中浸泡一段时间后用钢钳垫以布片，夹住针阀尾部轻轻转动，慢慢拔出，也可用针阀拉出器拉出针阀。方法：卸掉蝶形螺母、压板，将针阀锁夹、锁夹座组合、压板螺杆一起抽出（这三个零件组装在一起，不需拆开）。再将压板螺杆退出两圈，松开针阀锁夹，夹住针阀尾部，旋紧压板螺杆，然后将这一部分全部放进支承外套内，再旋进定位螺钉，装上压板。扳动蝶形螺母就可将针阀拉出。用铜丝刷清除喷油嘴头部的积碳，清除针阀锥面污物，用直径大小相应的钻头、通针或钢丝疏通喷油嘴油路和喷油孔。将喷油嘴偶件放在盛有柴油的盘中来回拉动针阀进行清洗。
柴油发电机喷油器的检验有这三点：
喷油器体。检查喷油器体各部位螺纹应完整，不得有滑扣等现象。检查喷油器体与喷油嘴偶件的接合面若有轻微锈蚀和划伤，可在平台上研磨修复。
喷油嘴偶件。外观检验：检查偶牛配合表面应色泽均匀、无损伤、无锈钟；检查偶件锥面密封带应明亮清晰、完整、无麻点和伤痕，密封带宽度还≤0.5mm。滑动性检验：喷油嘴偶件用柴油浸泡后，将喷油嘴45°，抽出针阀约1/3长度，转至任何角度松手后，针阀应能借助自重下滑，并均匀、无阻滞地滑到底。密封性检验：偶件的配合间隙，一般不直接进行测量而是通过密封性试验来检验。将喷油器装在喷油器试验器上，均匀缓慢地用手柄压油，同时增加弹簧预紧力，直到油压在23～25MPa压力下油，观察压力表指针从29MPa下降到18MPa所经历的时间，正常应为9～20s。如果所经历时间少于9s，表明配合间隙太大，可能是接头处漏油，针阀体与喷油器体平面配合不严、密封锥曲封闭不严或导向部分磨损等原因引起，油压下降时间过长，表明有卡滞现象。
