| 故障诊断与排除测试步骤 | 数值 | 结果 |
|---|---|---|
| 1. 喷油器套筒泄漏和/或密封件损坏 A. 拆下气门机构盖。 B. 从缸盖上拆下喷油器。 有关详细信息，参考拆解和装配手册。 测试期间，请勿让冷却系统上的压力超过 103 kPa (15 psi)。 施加过高压力可能会导致冷却系统损坏。 C. 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。 冷却液也有可能污染燃油系统。 发动机停机后，冷却系统中滞留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它燃油系统部件损坏。 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。 |

结果：喷油器套筒泄漏。 修理：拆下泄漏的喷油器套筒。 仔细检查套筒是否损坏。 如果喷油器套筒上有可见的损坏迹象，更换套筒。 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。 冷却液也有可能污染燃油系统。 发动机停机后，冷却系统中滞留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它燃油系统部件损坏。 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。 如果气缸中充满油液，请不要盘动发动机。 否则可导致发动机严重损坏。 排空所有气缸中的油液后再尝试起动发动机。 |
