| 故障诊断与排除测试步骤 | 数值 | 结果 |
|---|---|---|
1. 润滑 A. 拆下气门机构盖。 请参考拆解和组装, "气门机构盖 - 拆卸和安装"以了解正确步骤。 B. 让发动机盘车，检查阀门室中的润滑情况。 确保阀门室中有足够的发动机机油流量。 发动机机油通道必须清洁。 注：气门机构盖拆下时，不要运转发动机。 |
润滑 |
结果：气门机构的油流不足。 确保发动机机油油道清洁。 结果：气门机构的油流正常。 转至测试步骤 2。 |
2. 配气机构部件 A. 检查配气机构的下述部件有无异常或过度磨损，平直度和清洁度如何： · 摇臂 · 推杆 · 液压升降机 · 凸轮轴 · 气门杆 · 摇臂轴 |
配气机构部件 |
结果：配气机构部件磨损、弯曲或不清洁。 修理或更换部件。 参考拆解和组装。 注：如果更换凸轮轴，则也必须安装新的气门挺杆。 结果：所有配气机构部件正常。 请联系代理商解决方案网络 (DSN)。 |
