Abstract
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.
