摘　　要：再制造发动机被公认为节能、节材、经济和环保,是实现循环经济和可持续发展的一种重要手段.生命周期评价(LCA)是一种评估产品从原材料开采、运输、制造、用户使用到最终处置的潜在环境影响的方法.系统研究了排放标准对再制造发动机环境效益的影响,并分析了跨标准阶段使用情景下的环境损伤.针对跨标准阶段再制造原型机的环境损伤问题,提出了两种解决方案,并分析了两种升级再制造方式对环境的影响.结果表明:跨标准阶段使用的再制造原型机会增加环境影响.两种升级再制造方法可以弥补排放标准的限制:油改气方法的能源消耗高,环境性能好;安装后处理设备会增加资源消耗,臭氧层破坏潜值显著增加,但其他环境指标将减少.Remanufactured engines are recognized as energy-saving,material-saving,economical and environmentally friendly,and it is a means to achieve circular economy and sustainable development.Life cycle assessment(LCA)is a method that evaluates the potential environmental impact of a product from raw material mining,transport,manufacturing,user use to final disposal.The impact of emission standards on the environmental benefits of remanufactured engine is studied systematically,and the environmental damage in cross-standard stage use scenarios is analyzed.Aiming at the problem of environmental damage of original remanufactured engine used in cross-standard stages,two solutions are proposed and the environmental impact of the two upgrade remanufacturing methods is analyzed.The results show that original remanufactured engine used in cross-standard stages increases environmental impact.The two upgrade remanufacturing methods can compensate for the emission standard restrictions:the energy consumption of oil-to-gas is high,and the environmental performance is good;the installation of after-treatment devices will increase resource consumption,and the ozone depletion potential will increase significantly,but other environmental indicators will decrease.
