Abstract

As the mass production and mass consumption industries are settled, they are promoting depletion of natural resources and causing the problem of global warming. Therefore, various studies are under way to pursue resource utilization and environmental protection at the same time. In Europe and the United States, the remanufacturing industry, which was settled early, has emerged as an alternative industry to mitigate resource and environmental problems. In this research after using a diesel engine, the engine parts were restored just before disposal. The cylinder block was selected according to weight and economic value. The mass of the selected cylinder block is about 246 kg. When the worn parts were restored, the restoration process used about 200 g of mass. as the result of restoration process, weight 246 kg cylinder block was prolonged the lifetime by using 200g.

Keywords:
