- 附属设备
- 配气机构部件
- 活塞
- 连杆和主轴承
- 隔离噪音源。 拆下可能有故障的发动机附件。 检查可能有故障的发动机附件。 如果发现任何缺陷,请修理和/或更换发动机附件。
- 如果机械噪音依然很明显,请参阅"配气机构部件"。
- 拆下气门机构盖。 检查下列部件有无损坏:凸轮轴, 气门弹簧, 挺杆, 推杆 和 气门桥。 彻底清洁配气机构部件。 如果更换凸轮轴,则也应更换气门挺杆。 确保所有气门都能自由运动。 更换所有损坏的零件。
- 如果机械噪音依然很明显,请参阅"活塞"。
- 检查活塞有无损坏和磨损。 更换所有损坏的零件。
- 如果机械噪声仍然很明显,请参阅"连杆和主轴承"。
检查连接杆和主轴承。 此外,请检查曲轴轴承表面(轴颈) 更换所有损坏的零件。
