Recently, the key technologies and equipments for automobile remanufacturing of SINOTRUCK HOWO Fuqiang Power Co.,Ltd, a national science and technology support program in the twelfth-five year plan, got approval with approval number 2011BAF11B07.This was another important national scientific program Fuqiang Co.,Ltd got, after successfully fulfilling the eleventh five-year plan programs. With high added value, easy wear failure, complex structure and multiple sub components, the typical parts of the process route are used to manufacture green cleaning, nondestructive testing, re manufacturing evaluation and quality control evaluation. When the program is complete, the product quality and technical level is not lower than the new product.In common technologies, methods and equipment research，it will form 20 to 30 independent intellectual property rights in the from academic thesis,  national invention patents and standards. The program concerns 3 to 5 invention patents and 5 technology standards which will guide corporate production and will be submitted to the state government for archive. Compared with new engines, the remanufacturing engines with these technologies will save a costs of 30 million RMB for the company; compared with old engines re-melt, it will save 6,750,000 kilowatts, which equals saving 2,500 tons standard coal and reducing 30,000 tons of carbon dioxide. In general, it will resolve the key technology ,and promote the development of enterprises.
