The running in of diesel generator set is a necessary measure to prolong its service life. There are geometric errors (positional accuracy errors) and micro unevenness (bumps and dents formed by machining marks) in diesel engine assembly and main friction pair parts, such as cylinder and piston, piston ring, crankshaft journal and bearing, etc. Therefore, the actual contact area of the two parts is small, but the load per unit area is large, so the friction and wear are serious. In addition, the oil film is not easy to be damaged due to the uneven surface. If the diesel engine works at high speed and high load, the bumps on the surface of the friction pair parts will be seriously scratched or torn, and the metal chips will become abrasives, which will aggravate the wear. In severe cases, local high temperature melting changes into dissolution wear, forming cylinder burning. In fact, due to the rough surface of the parts, the power consumed in friction is large, so the high load of diesel engine is equivalent to overload. As a result, it also aggravates the wear of parts.

柴油发电机组磨合期较长，而初期磨合阶段磨损量较大，因此，此阶段一般以工厂内进行，通过合理的磨合规范进行磨合，以减少磨损量，延长使用寿命，同时通过磨合期可以用来检查和调整柴油机的装配质量和性能参数，以及运行中出现的问题，以便及时排除，使柴油机质量和性能达到规范的要求。

The running in period of diesel generator set is long, while the wear loss in the initial running in stage is large. Therefore, this stage is generally carried out in the factory, and the running in is carried out through reasonable running in specifications, so as to reduce the wear and prolong the service life. At the same time, the running in period can be used to check and adjust the assembly quality and performance parameters of diesel engine, as well as the problems in operation, so as to eliminate them in time, The quality and performance of diesel engine can meet the requirements of specification.

新的或经大修后的柴油发电机组，在正式使用前须经60h磨合运转，方可投入全负荷使用，以改善柴油机各运动部件的工作状况，提高柴油机的运行可靠性和使用寿命。磨合应视柴油机用途和拖载方式的不同，来考虑具体磨合方案。原则上随着磨合时间的增加，分阶段逐步提高柴油机的转速和负载，在整个磨合期内负荷以12h标定功率的50%~80%为宜，转速应不大于标定转速的80%为好。但在磨合的开始阶段，空运转或过小负载情况下的运转时间不宜过长。每当修理更换过缸套、活塞、活塞环、连杆轴瓦和曲拐等零部件后，亦应按上述磨合工况适当进行短期磨合。

The new or overhauled diesel generator set can be put into full load operation only after running in for 60 hours before formal use, so as to improve the working conditions of all moving parts of diesel engine and improve the operation reliability and service life of diesel engine. The specific running in scheme should be considered according to the different use of diesel engine and different towing mode. In principle, with the increase of running in time, the speed and load of diesel engine should be gradually increased in stages. During the whole running in period, the load should be 50% ~ 80% of the rated power of 12h, and the speed should not be greater than 80% of the rated speed. However, the running in period should not be too long under the condition of small load. Whenever the cylinder liner, piston, piston ring, connecting rod bearing bush, crank and other parts are repaired and replaced, the short-term running in should be carried out according to the above running in conditions.
