Following the introduction of the Internal Combustion Engine Remanufacturing Promotion Plan at the beginning of 2014, Yuchai Group , the leading domestic enterprise, took another step forward in remanufacturing. Recently, Yuchai Corporation and Caterpillar (China) Investment Co., Ltd. have reached an agreement to buy out the latter’s joint venture company, Yuchai Remanufacturing Industry (Suzhou) Co., Ltd. (hereinafter referred to as “Yuchai Remanufacturing Company”). 49% of the shares are fully controlled and Yuchai Remanufacturing Company becomes a wholly-owned subsidiary of Yuchai.

Significant

Yuchai Remanufacturing Corp., a joint venture between Yuchai and Caterpillar in April 2010, was put into operation in 2011 and mainly provides remanufacturing services for diesel engines and components produced by Yuchai and Caterpillar. After years of operation, Yuchai Remanufacturing Company has completed the accumulation of technology and management, and its operating level has been increasing year by year.

Yuchai also signed a technical agreement with Caterpillar and Caterpillar will continue to provide technical support to Yuchai Remanufacturing Company. Zhu Jihui, deputy general manager of Yuchai Remanufacturing Company, stated that with the change in the mode of shareholder cooperation, the company’s operating and management rights will be returned to Yuchai’s parent company and will be fully integrated into the planning and planning of Yuchai’s shares, and the company’s business management, product planning, After-sales service and other aspects accept the leadership and management of Yuchai.

It is reported that by the end of the "Twelfth Five-Year Plan", the remanufacturing of China's internal combustion engine industry will form a production capacity of 350,000 sets. Compared with the original manufacturing, remanufacturing can save 80% of energy consumption, save more than 70% of materials, and reduce manufacturing costs by 30% to 50%. The economic and social benefits of internal combustion engine remanufacturing are very significant. It is an initiative that promotes the sustainable development of the internal combustion engine industry, promotes energy conservation and emission reduction, and builds a “two-type” society with important practical significance and far-reaching strategic significance.

The remanufacturing of internal-combustion engines refers to the dismantling, component cleaning, testing and classification of the failed internal combustion engine, and the re-manufactured internal-combustion engine's service life and its power after remanufacturing and manufacturing according to the requirements of the original new product technical specification. The indicators such as sex, economy, environmental protection, and reliability are not lower than the standard requirements of the new aircraft prototype.

Industry experts believe that the implementation of internal combustion engine remanufacturing to benefit the country and the people can not only realize the utilization of a large number of failed products, but also help cultivate new economic growth points to speed up the development of recycling economy and build a resource-saving and environment-friendly society. The practice of domestic and foreign industries shows that most of the important components such as cylinders and crankshafts of end-of-life internal combustion engines are partially failures. Through remanufacturing such as forming and repairing, the dimensions, accuracy, and performance can be restored without changing the shape and the material of the body. . Compared with the traditional waste metal recycling and disposal methods, remanufacturing can recover about 70% of the added value of scrapped products; compared with the original manufacturing, remanufacturing can save 80% of energy consumption, save more than 70% of materials, and reduce manufacturing costs. 30%~50%; Remanufacturing of internal combustion engines can not only reduce waste, but also bring about considerable environmental benefits, as well as save energy and materials, and have significant economic and social benefits.

Highlight focus

From the perspective of the development direction and major tasks of the remanufacturing of internal-combustion engines, the “Recommissioning Plan for Remanufacturing Internal Combustion Engines” issued by the Ministry of Industry and Information Technology clearly points out the current key tasks, namely: highlight key areas, form the industrialization scale of internal combustion engine remanufactured as soon as possible, accelerate technological innovation, and vigorously Improve remanufacturing technology capabilities and equipment levels; develop reverse logistics to ensure stable supply of remanufactured old parts; improve the standards system, strengthen information supervision, and standardize remanufacturing production behavior.

Taking the diesel engine, the main product of the current internal-combustion engine industry remanufacturing, as an example, the key components include the cylinder block, cylinder head, crankshaft, connecting rod, camshaft, gear chamber, and flywheel housing; internal combustion engine accessories include supercharger, Generators, starters, oil pumps, fuel pumps, pumps, and other components with high added value. It is understood that some foreign companies and joint venture companies such as Caterpillar, Cummins, Dongfeng Cummins, and Bosch have already carried out turbocharger, fuel pump, fuel injection pump, fuel injector, etc. due to their integrated technology features. Remanufacture of some high value-added products. Some of the major domestic remanufacturers, such as Weichai, are also working with their respective suppliers to promote the remanufacturing of main accessories.

Although there are many advantages in remanufacturing, due to various reasons, the scale of the industry has not yet formed in China. The current situation in China is that the relevant companies have different requirements for after-sales products, and users lack understanding of remanufacturability, performance, and after-sales services, causing many users to worry about whether or not to use remanufactured products.

The main goal of the internal combustion engine remanufacturing promotion plan issued by the Ministry of Industry and Information Technology this year is: By the end of the “Twelfth Five-Year Plan”, the remanufacturing production capacity, enterprise scale, and technical equipment of the internal combustion engine industry will be significantly improved. Industry-wide remanufacturing capacity of 350,000 sets of various types of internal-combustion engines, 6 to 8 complete machine remanufacturing enterprises of 30,000 units, and more than 6 complete machine remanufacturing enterprises of 30,000 units or less; superchargers, More than 30 large-scale supporting enterprises for key components such as generators, starters, oil pumps, fuel pumps, and water pumps have further increased the scale of the internal combustion engine remanufacturing industry.
