可能原因

喷油器衬套或喷油器衬套密封件

  • 喷油器套筒泄漏和/或密封件损坏

建议的措施

喷油器套筒泄漏和/或密封件损坏

  1. 拆下气门机构盖。

  1. 从缸盖上拆下喷油器。

    ------ WARNING! ------

    热的冷却液、蒸汽和碱会造成人身伤害。

    在工作温度下,发动机冷却液是热的而且处在压力下。 散热器和所有到加热器的管路或发动机中都有热的冷却液或蒸汽。 与它们的任何接触都会造成严重烫伤。

    只有当发动机停机且散热器盖已经冷却到可以徒手触摸时,再慢慢拆下过滤器盖以释放压力。

    冷却系统调节器含碱。 应避免它与皮肤和眼睛接触。


  1. 对冷却系统加压以识别泄漏的喷油器套筒。 近距离检查喷油器套筒顶部周围的密封接合处。 泄漏的喷油器套筒上会滴下少量冷却液。 有关测试冷却系统的步骤,请参阅系统操作/测试和调整。

  1. 拆下泄漏的喷油器套筒。 有关拆卸喷油器套筒的步骤,请参阅拆解和装配手册。 更换衬套。 更换喷油器套筒的 O 形密封圈并重新安装套筒。 更换任何损坏的部件。

    注: 冷却液也有可能污染燃油系统。 发动机停机后,冷却系统中保持的压力可能导致冷却液流入燃油系统。 肉眼检查燃油箱中有无冷却液。 冷却液污染燃油系统可能导致喷油器和其他燃油系统部件损坏。 确保所有的燃油系统部件都处于良好状况后,再将发动机重新投入使用。
