Coolant Contains Fuel

Usage:

C15 115

可能的原因

  • 喷油器衬套或喷油器衬套密封件

建议措施

喷油器衬套或喷油器衬套密封件

  1. 拆下气门机构盖。

  1. 从缸盖上拆下喷油器。

    有关详细信息,请参考拆解和组装手册。

    ------ 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. 对冷却系统加压以确定发生泄漏的喷油器衬套。 仔细检查喷油器衬套顶部周围的密封接头。 少量的冷却液将会从发生泄漏的喷油器衬套上滴落。

    注: 测试过程中,冷却系统中的压力不得超过 103 kPa (15 psi)。 施加过多的压力可能会损坏冷却系统。

    有关详细信息,请参考系统操作/测试和调整。

  1. 拆下发生泄漏的喷油器衬套。 仔细检查衬套是否损坏。 如果喷油器衬套上有明显的损坏迹象,则更换衬套。 更换喷油器衬套上的 O 形密封圈并重新安装衬套。 更换所有损坏的部件。

    注: 冷却液也可能会污染燃油系统。 在发动机停机后,冷却系统中保持的压力可能会将冷却液输送到燃油系统中。 目视检查燃油箱中有无冷却液。 冷却液对燃油系统造成的污染可能会损坏喷油器和其他燃油系统部件。 在使发动机重新投入使用前,确保所有燃油系统部件都状况良好。
