The internal standard of the internal combustion engine will be formally implemented on January 1, 2014. Currently, the internal combustion engine of the National Three Standards has gradually withdrawn from the market. At the same time, the quality of parts and components that are matched with the National IV engine will become the key to whether the National IV diesel engine can guarantee normal operation.
Recently, at the International Symposium on Reliability Technology for Internal Combustion Engines sponsored by the Automotive Industry Association of the China Association of Automobile Manufacturers, Ye Shengji, deputy secretary-general of the China Association of Automobile Manufacturers, raised this phenomenon. He believes that the reliability of China's internal combustion engine products is not high. The main reason for the low-end market.
For the stricter technical requirements of the National Diesel Engine, its requirements for supporting components are also high, especially in its reliability put forward more standards. This has brought new challenges to internal combustion engine parts and components, standardized various technical regulations, adopted a common and mature technical route, and raised relevant industry standards to promote the reliability of internal combustion engines. This has become a concern in the industry.
â— Upgrading Nation 4 is a challenge
For the implementation of State IV, it brought new challenges to the internal combustion engine parts and components companies. Lu Zhuohua, deputy general manager of Dongfeng Cummins Engine Co., Ltd., said: “Energy-saving and emission-reduction require improving the engine's combustion efficiency, cylinder pressure, heat load, and injection pressure. These are challenges to the reliability of the internal combustion engine and require the internal combustion engine to be used in the development process. Applications, component tolerances, high mechanical loads, thermal loads, friction and wear capabilities have been greatly improved."
The implementation of State IV not only has more technical requirements in the research and development of internal combustion engines, but also raises higher standards in the manufacturing process, and the requirements for processing technology and processing accuracy are also increasing. At the present stage, China is facing the late start of diesel engine exhaust aftertreatment and the fast upgrade of emission standards. The research of reliability requires a large amount of basic data, feedback and improvement of actual measurement. Within a short period of time, R&D, reliability research and batch production process are completed. The rapid development of production and production capacity is undoubtedly a huge challenge for domestic post-processing companies.
It is understood that companies such as Weichai, Yuchai, Xichai, and Dongfeng Commercial Vehicles have actively explored the application of reliability technology and gained valuable practical experience; various research institutes and universities at home and abroad have increasingly studied the reliability of the internal combustion engine. In-depth and achieved a number of phased results, these have played a huge role in the research and application of reliability technology in the internal combustion engine industry.
Engine core components are characterized by high reliability, durability, and high precision. Engine OEMs will consider suppliers' historical experience, R&D and innovation capabilities, production assurance capabilities, quality assurance capabilities, cost control capabilities, and financial status. Elements to target suppliers. Before components are mass-used in engine manufacturing, they need to go through manual samples, performance tests, tooling samples, bench tests, environmental tests, vehicle road tests, and small batch and mass production. It usually takes two hours. Around the year, the development and verification process requires a lot of manpower and capital costs. Therefore, the industry's salient features are: suppliers are very cautious about fixed-point selection, and the relationship between parts suppliers and engine manufacturers is relatively stable once they are established.
At present, in the domestic market, some engine components with low technological content, low added value, and high transportation cost have basically achieved domestic matching; however, hydraulic tappets, hydraulic tensioners, rocker arms and variable Valve engine core components and other components, well-known car host manufacturers in order to ensure the successful development of products, reliable quality, generally adopts the principle of careful localization. With the improvement of product quality and technical level of domestic domestic companies, they are gradually starting to purchase from domestic domestic companies.
â— Internal combustion engine remanufactured into hot
Compared with the previous engine, Guoji Diesel Engine has higher costs and advanced technology, and it is precisely because of this that the value of remanufacturing in the National IV diesel engine is even higher. Not long ago, the China Internal Combustion Engine Industry Association convened the "Mechanical Engine Remanufacturing Promotion Plan" promotion meeting. Representatives from more than 20 provinces and cities attended the conference. According to the promotion plan, by the end of the “Twelfth Five-Year Planâ€, 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.
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 understood that remanufactured products can recover about 70% of the added value of scrapped products compared with the traditional methods of recycling and disposal of scrap metal. Compared with the original manufacturing, remanufacturing can save 80% of energy consumption and save more than 70% of materials. Reducing manufacturing costs by 30% to 50%; Remanufacturing of internal combustion engines can not only reduce waste, but also have considerable environmental benefits, and can also save energy and materials, as well as economic and social benefits.
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 wasteâ€, 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.
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.
In November last year, the Ministry of Industry and Information Technology released the “Recommissioning Plan for Internal Combustion Engines†and proposed the goal of significantly improving the remanufacturing production capacity, enterprise scale, and technical equipment level of the internal combustion engine industry by the end of the “Twelfth Five-Year Planâ€.
The plan makes it clear that remanufacturing demonstrations will be carried out mainly in the medium- and heavy-duty commercial vehicle engines, passenger car engines, and other areas in the demonstration of the entire engine and key parts remanufacturing project. In the key component remanufacturing demonstration project, demonstrations are mainly conducted in the fields of supercharger, generator, starter, oil pump, fuel pump, and water pump.
By the end of the “Twelfth Five-Year Planâ€, the entire industry has formed a remanufacturing capacity of 350,000 sets of various types of internal combustion engines. Established a number of demonstration projects for the remanufacturing of internal combustion engines such as passenger cars, medium and heavy commercial vehicles, construction machinery, agricultural machinery, power generation equipment, ship power, petroleum machinery, and railway locomotives.
â— Parts and components have room for improvement
China's auto industry has been affected by the ideology of heavy-duty parts and re-introduction of light autonomy. As a result, China’s auto parts industry has not been able to develop synchronously with the entire vehicle industry for a long time. At present, in the domestic automobile market, foreign investment (55% of which are exclusively foreign-owned enterprises and 45% are joint ventures) controls the market share of key automotive parts up to 70% and are mainly concentrated in non-key parts and components markets.
It is also due to the relative lag in the development of local parts and components companies. It is also difficult to open the market in the international market and enter the overseas automobile industry chain. Moreover, many domestic automobile manufacturers, most of them are joint ventures with foreign companies, and local brands such as parts and components and related industrial chains are also faced with difficulties in access.
Especially in the field of internal combustion engine components, at present, the key core technologies and core component assemblies of the domestic engine parts industry are mostly owned by foreign large-scale auto parts companies, and most local-owned engine parts and components companies still have low production technology. The labor-intensive products with low added value are the main products. The lack of core technologies, lack of R&D investment, poor ability to independently innovate, poor management, and low skilled workers all constrain the development of China's local engine parts and components companies.
Although China has become the world's largest automotive production and consumer market, as the consumer market changes toward diversification and individuation, China's auto market has gradually transformed into a buyer's market, and market competition will become increasingly fierce. In the long run, the continuous decline in vehicle prices will be an irreversible trend, and the overall sales price of single models will also show a downward trend.
Affected by cost pressures from OEMs' price cuts, parts and components of a single model will face constant pressure to reduce prices. Therefore, suppliers of parts and components must cope with the pressure of falling prices by continuously increasing production efficiency, reducing costs, and expanding production and sales scale. At the same time, we will continue to introduce new products and new models through simultaneous R&D and advance research and development to expand new profit growth points.
Therefore, we have increased investment in R&D, learned to introduce advanced foreign design and processing technologies, especially technological upgrades in high-value-added high-tech engine products such as State IV, and gradually realized the development of complementary products with independent intellectual property rights. China's engine parts industry will gain greater room for development.
