The government continues to promote the remanufacturing of internal combustion engines.

Entrusted by the Ministry of Industry and Information Technology, the China National Internal Combustion Engine Industry Association held the advancement meeting of the "Internal Combustion Engine Remanufacturing Promotion Plan" in Zhangjiagang, Jiangsu Province from May 26 to 27. Representatives from more than 20 provinces and cities attended the conference. According to the promotion plan, by the end of the “Twelfth Five-Year Plan”, the production capacity, enterprise scale, and technical equipment level of the remanufacturing of the internal combustion engine industry will be significantly improved, and the whole industry will form a remanufacturing production capacity of 350,000 sets of various types of internal combustion engine machines. At the same time, the "Engine Remanufacturing Industry Alliance" was established.

Government promotes remanufacturing of internal combustion engines

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.

It is reported that, compared with the traditional recycling and disposal methods of scrap metal, 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 over 70% of materials, and reduce The manufacturing cost is 30% to 50%; the remanufacturing of the internal combustion engine not only can reduce waste, but also has considerable environmental benefits, as well as energy saving and material saving, as well as significant economic and social benefits.

As early as 2005, the State issued a document stating that it “supports the remanufacture of used mechanical and electronic products” and listed the “green remanufacturing technology” as the key and common feature of relevant departments of the State Council and local people’s governments at all levels to increase funding support. One of the projects.

At present, China has long been a major manufacturer of internal combustion engines. It is reported that by the end of 2013, the social possession of China's internal combustion engine products was 380 million units. Such a large amount of internal combustion engine reserves provides a realistic possibility for the development of the internal combustion engine remanufacturing industry.

In 2013, the Ministry of Industry and Information Technology released the “Internal Combustion Engine Remanufacturing Promotion Plan”, which clearly stated that “the key to the implementation of the entire engine and key parts and components and remanufacturing of internal combustion engines, the efficient and clean upgrading and remanufacturing of internal combustion engines, the remanufacturing technology and equipment upgrade, and the remanufactured reverse logistics The construction of special key projects such as system construction and the construction of an auxiliary service system for internal combustion engine remanufactured to form a remanufactured production capacity of 350,000 compressor engines and a large-scale, batch remanufacturing production capacity for key components and components, and preliminary establishment of recycling of old parts in the internal combustion engine industry. Create a reverse logistics system."

From the perspective of the development direction and major tasks of the remanufacturing of internal-combustion engines, the promotion plan clearly points out the current key tasks, namely: highlighting key areas, establishing the industrialization scale of internal combustion engine re-manufacturing as soon as possible, accelerating technological innovation, and vigorously upgrading remanufacturing technology capabilities and equipment levels. Develop reverse logistics, ensure stable supply of remanufactured old parts, improve standards system, strengthen information supervision, and standardize remanufacturing production behavior.

Yang Tie-sheng, deputy director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, stated that after years of accumulation, China has entered the peak period of mechanical and electronic product scrapping. If it is confined to the traditional mode of production and consumption of “mass production, mass consumption, and large amount of waste”, it will not be realized. Waste recycling, resources, energy and the environment will be difficult to sustain. This requires that we must seek a sustainable mode of production and consumption, and accelerate the development of industrial recycling in order to break the constraint on energy resources and ease the pressure on the ecological environment. In this context, the remanufacturing industry follows the trend.

Xing Min, executive vice president and secretary-general of the China Internal Combustion Engine Industry Association, introduced that the internal combustion engine industry is an important basic industry in China, with long industry chain, high correlation, wide employment, and large consumer spending. The internal combustion engine has a large amount of use, a wide range, and a high thermal efficiency, and is currently the most efficient mobile power machine that humans can grasp. Like the automobile industry, as the world’s largest manufacturer of internal combustion engines, the widespread application of internal combustion engine products and the continuous development of the manufacturing industry are crucial to safeguarding national security and the healthy development of the national economy.

Yang Tiesheng stated that accelerating the development of the remanufacturing industry is an inevitable requirement for promoting the development of the industrial cycle and an important measure for building a conservation-oriented and environment-friendly society. The implementation of the internal combustion engine remanufacturing promotion plan needs to strengthen industrial cooperation. It requires relevant personnel to work hard along the established direction and will surely achieve the desired goals.

Establishing alliances to condense industrial forces

The remanufacturing of internal-combustion engines is a systematic project. For example, diesel engines, the main product of the remanufacturing of the internal combustion engine industry, include cylinder blocks, cylinder heads, crankshafts, connecting rods, camshafts, gear chambers, and flywheel housings. Internal combustion engine accessories include turbocharger, generator, starter, oil pump, fuel pump, water pump and other components with high added value. With the limited power of a single company, forming a coalition by forming coalitions is an inevitable choice to promote the development of internal combustion engine remanufacturing.

Under the guidance of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology of the People's Republic of China, China National Association of Internal Control and Cooperation is responsible for organizing the establishment of an internal combustion engine remanufacturing industry alliance in association with relevant industry associations to be responsible for the organization, coordination and supervision of the remanufacturing demonstration and extension work.

Xing Min explained that the establishment of an internal combustion engine remanufacturing industry alliance can build a bridge between the government and the enterprise; it can give full play to the industrial coalition organization functions and overall coordination, and provide members with advice on market information, laws and regulations, etc. to implement the " The General Office of the State Council on Strengthening the Energy-saving and Emission-reduction of Internal-combustion Engine Industry and the "Recommissioning Plan for Internal Combustion Engines" issued by the Ministry of Industry and Information Technology.

Xing Min introduced that the purpose of the alliance is to integrate the research, design, manufacturing and equipment innovation resources of the upstream and downstream industrial chain of internal combustion engine remanufacturing, to break through bottlenecks that hinder the development of the industry, to highlight key points, to cooperate in a coordinated manner, to lead the demonstration, and to improve the internal combustion engine. Manufacturing technology and equipment level and industrialization capabilities, to achieve the scale of the internal combustion engine remanufacturing industry, standardized development, and promote industrial restructuring and industrial upgrading.
