3.3 柴油机长期存效时的维护保养
Maintenance of Diesel Engine during Long-term Storage
为防止锈蚀，柴油机出公司时进行油封，一般柴油机的油封期为一年，凡超过一年的
应进行检查并采取必要的补充措施。
In order to prevent rust and corrosion, the diesel engine is oil sealed before ex-work.
Usually, the oil seal period for the diesel engine is one year. Whenever the oil seal period
exceeds one year, check and take necessary supplementary measures.
油封：首先向柴油机加入机油和带防锈剂的冷却液，开机并空转达 15-25 分钟，在
停机前 2 分钟向空气压缩机进口喷油封油，停车拆除中冷器与发动机的连接管路，以起
动机带动发动机转动，向发动机进气管、涡轮增压器等内腔喷油封油。向所有的裸露表面
和轴伸出端涂油封油。
Preservation: First fill the diesel engine with sealing oil and coolant with anti-rust agent,
start the engine and run at idling speed for 15~25min. Spray sealing oil to air compressor intake
2min before stopping of the engine. After stop, remove the pipeline connecting intercooler and
engine, so that the starter drives the engine to rotate. The sealing oil is sprayed into the cavities
of intake pipe, turbo-supercharger, etc. Apply sealing oil on all the exposed surfaces and the
extended shaft ends.
存放期间的防护：用盖子或塑料布捆扎封墙各油、气、水的进出口；用气象防锈膜
封存整台发动机。
Protection in storage period: Use covers or plastic cloth to tie and block all the intake and
outlet ports. Use weather anti-rust film to seal the whole engine.
如果需要运输则应该外加包装。
Pack the engine if transportation is necessary.
