| Abstract: |
| 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 remanufacturing 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 %. |
