喷油器滴油 　　当喷油器工作时，针阀体的密封锥面会受到针阀频繁的强力冲击，再加上高压油流不断地从该处喷射出去，锥面会逐渐出现刻痕或斑点，从而丧失密封，造成喷油器滴油。当柴油机温度低时，排气管冒白烟，机温上升后则变成黑烟，排气管会发出不规则的放炮声。此时若停止向该缸供油，排烟和放炮声就会消失。这时可拆开喷油器，在针阀头部沾少许氧化铬细研磨膏(注意不可沾在针阀孔内)对锥面进行研磨，用柴油洗净，装入喷油器试验。若仍不合格，则需更换针阀偶件。 2.2　喷油器雾化不良 　　当喷油压力过低，喷孔磨损有积碳，弹簧端面磨损或弹力下降时，都会致使喷油器提前开启，延迟关闭，并形成喷油雾化不良的现象。若是单缸柴油机就不能工作，多缸柴油机则功率下降，排气冒黑烟，机器运转声也不正常。由于粒径过大的柴油雾滴不能充分燃烧，便顺缸壁流入积油盘，使机油油面增高，粘度下降，润滑恶化，还可能引起烧瓦拉缸的事故。此时应将喷油器拆开清洗，检修，重新调试。 2.3　喷孔扩大 　　由于高压油流不断地喷射冲刷，针阀喷孔会逐渐磨大，导致喷油压力下降，喷射距离缩短，柴油雾化不良，缸内积碳随之增加。单孔轴针式喷油器孔径一般大于1 mm，可在孔端放一颗直径为4～5 mm的钢球，用锤轻轻敲击，使喷孔局部发生塑性变形而缩小孔径。多孔直喷式喷油器由于孔数多，孔径小，只能用高速钢磨制的冲样在孔端轻轻敲击，若经调试仍不合格，则应更换针阀偶件。 2.4　针阀咬死 　　柴油中的水分或酸性物质会使针阀锈蚀而被卡住，针阀密封锥面受损后，缸内可燃气体也会窜入配合面中形成积碳，使针阀咬死，喷油器便失去喷油作用，致使该缸停止工作。可将针阀偶件置于废机油中加热至沸腾冒烟为止，取出，用垫着软布的手钳夹住针阀尾部慢慢活动，将其抽出沾上清洁机油，让针阀在阀体内反复活动研磨，直到把针阀偶件倒置时针阀能从阀体内自行缓缓退出为止。若装入喷油器试验不合格，则应更换针阀偶件。
