建议的措施

紧急停机开关

确认紧急停机开关处于 RUN(运转)(离开)位置。 如果压下开关,将会禁止发动机盘车。 请参阅故障诊断与排除, "紧急停机开关电路 - 测试"。

蓄电池和/或蓄电池电缆

  1. 检查蓄电池接线柱和蓄电池电缆连接是否松动和有无腐蚀。 如果蓄电池电缆受到腐蚀,应拆下蓄电池电缆并清洁蓄电池电缆。 紧固任何松动的连接。

  1. 检查蓄电池。

    1. 向蓄电池充电。 请参阅专门说明书, SEHS7633, "蓄电池测试步骤"。

    1. 对蓄电池进行负载测试。 请参考专门说明书, SEHS9249, "针对 6、8 和 12 伏铅酸蓄电池的 4C-4911 蓄电池负荷测试仪 的使用"。

盘车起动电路

ECM 控制发动机的盘车循环。 发动机起动请求期间,ECM 向起动装置的起动马达磁开关 (SMMS) 供电。 确认盘车起动电路工作正确。 进行下述步骤:

  1. 检查应用的所有断路器。 如果断路器跳闸,调查原因。

  1. 检查 ECM 上 SMMS 的控制输入电压。

  1. 确保控制输入电压到达 SMMS。

  1. 检查 SMMS 辅助电路的输入电压。

  1. 检查 SMMS 辅助电路的输出电压。

发动机盘车起动期间的正确电压应等于蓄电池电压。

如果任意一个电压不正确,应修理电路。

起动马达电磁阀或起动电路

  1. 测试起动马达电磁阀的工作情况。

  1. 检查通向起动马达电磁阀的导线。

起动马达或飞轮齿圈

  1. 测试起动马达的工作情况。

  1. 检查起动马达小齿轮和飞轮齿圈是否损坏。

发动机附件

  1. 确保传动系统运动自如。

  1. 确保正时销没有遗留在飞轮壳上。

  1. 拆下并检查任何可能会锁定发动机的发动机附件。

气缸液锁

拆下每一个单体喷油器,检查气缸内有无液体(气缸液锁)。

注: 将燃油从缸盖内放掉。 当单体喷油器被拆下来时,燃油将会从缸盖漏入气缸内。

发动机内部故障

  1. 拆解发动机。 参考拆解和装配。

  1. 检查内部部件有无下列情况:

    • 咬合

    • 部件折断

    • 部件弯曲
