摘　　要：阐述了再制造工程在循环经济中的地位和发展背景,剖析了废旧发动机在材料水平、零件水平和整机水平循环利用的节能效益和环保效益,讨论了再制造工程与表面工程的关系。研究表明,以再制造方式实施整机水平的循环利用,其节能效益和环境保护效益最佳,再制造1万台废旧发动机可节电1.45×108kWh,减少CO2排放0.6kt;表面工程在发动机再制造中的应用,可使发动机的旧件利用率由72.3%提高到90%。The status and development background of remanufacturing engineering in cyclic economy were described, the energy conservation profit and environmental protection effect of failed engines were analyzed, and the relationship between remanut^cturing engineering and surface engineering was discussed. The results showed that the energy conservation profit and environmental protection effect are the best when the failed engines are overall remanufactured. Remanufacturing 10000 engines, the energy could be saved by 14.5 millions kilowatt-hours and the emission of CO2 could be reduced by 0.6 thousands tons. The application of surface techniques in remanufacturing engineering could improve the utilization rato of old engine parts from 72.3 % to 90 %.
