摘    要:对3000台斯太尔发动机的统计分析表明,可直接利用的零件数量占23.7%,重量占14.4%,价值占12.3%;经再制造加工可以使用的零件数量占62%,重量占80.1%,价值占77.8%,说明对旧发动机进行再制造有良好的基础。按年产l万台再制造发动机统计,可回收附加值3.59亿元,节省金属8.5kt,创造税金0.36亿元,节电1600万度,减少CO2排放13~17kt,并可提供330人的就业机会;旧发动机中62%的失效零件可以运用表面工程技术进行修复,修复后的表面性能优于新品。先进表面工程技术在发动机再制造中的应用,提高了旧品利用率,降低了再制造成本,不仅使企业获得了经济效益,还为国家节能、节材、保护环境作出了贡献。

关 键 词:发动机  再制造  表面工程  效益

Abstract:The statistic analysis of 3 000 STYLE modl engines showed that among the engines parts, about 23.7 % in quantity, 14.4 % in weight and 12.3 % in value could be directly reused. Meanwhile, after remanufacturing about 62 % in quantity, 80.1 % in weight and 77.8 % in value could be reused. That means, remanufacturing of old engines had excellent economic benefits. Suppose ten thousands engines could be remanufactured per year, the following benefits would be obtained: reclaiming additional values of 3.59 hundreds millions Yuan RMB, saving metallic materials 8.5 thousands tons, creating profits and taxes of 0.36 hundreds millions Yuan RMB, saving energy of 16 millions kilowatt-hours, reducing emission of CO2 about 13~17 thousands tons, and providing employment for 330 persons. By using surface engineering techniques, about 62 % waste parts in old engines could be repaired, and the quality of remanufactured engines became superior to the original products. The applications of advanced surface engineering techniques in engine remanufacturing have enhanced the availability of waste products, reduced the remanufacturing costs and made contributions to materials- and energy-saving and environment protection.
Keywords:engine  remanufacturing  surface engineering  benifit
