Lack of core technology challenges the internal combustion engine industry

"China is at the juncture of transforming from a large internal combustion engine to a powerful country, and the internal combustion engine industry is facing severe challenges in technology, market and industrial structure adjustment." Xing min, executive vice president and Secretary General of China internal combustion engine industry association, said at the fourth second member congress and the fourth second director (expanded) meeting of the association

the challenge of rapid technological development

internal combustion engines have entered the high-tech era. Facing the increasingly stringent requirements of environmental protection, energy and sustainable development in countries all over the world, at present, large multinational groups and companies are using various high-tech means to develop low emission, ultra-low emission, quasi zero emission and zero emission technologies

in order to meet the increasingly stringent requirements of emission regulations, the development of low emission gasoline engines, diesel engines, single clean fuel (hydrogen fuel, etc.) engines and the research and development of electric, fuel cell power and hybrid power have become the main research directions of major automobile companies and engine companies in the world

Xing min pointed out that the innovation focus of internal combustion engines is energy conservation and emission reduction, and the development of diversified driving forces. The overall energy conservation and emission reduction standards and implementation schedule formulated by the state with reference to the international R & D level have brought great pressure to enterprises

the weak ability of independent innovation and the lack of the overall core technology of the industry are undoubtedly the severe challenges that China's internal combustion engine industry will face

challenges from the market Xing min believes that the challenges from market 3 are divided into three levels

first, multinational groups have listed the Chinese market as the focus of global strategic development, and have adopted the form of sole proprietorship or holding to set up factories in China, integrating them into the production base of their group's parts and engines

second, due to stricter environmental protection laws and regulations, rising prices of energy and raw materials, vicious market competition and other factors, low-end diesel engine products in the market have entered a difficult period of development, and the development of small internal combustion engines (motorcycle, general purpose, agricultural) has been restricted to a certain extent, which is difficult to meet the rapid growth needs of domestic and foreign markets; In the field of high-power diesel engines (marine, locomotive and fixed power station), it is urgent to digest, absorb and innovate after the introduction of technology, so as to solve the problem of the rapid development of the shipbuilding industry and the slow supply of independent brand main engines

third, the financial crisis hit economic entities and brought negative effects to the export of internal combustion engines

the challenge of industrial structure adjustment

industrial structure adjustment is the only way for China's internal combustion engine industry to grow from large to strong, and the challenge from structural adjustment is more complex. Xing min listed several important aspects

first, the industrial structure and product structure have characteristics, but they lack international market competitiveness at the technical level. The spare parts industry lacks the strength of independent innovation and development. Especially in the total market supply after the global economic recovery, it will face new challenges under the requirements of technology, materials and regulations. At present, the industry's coping strategies, programs and capabilities are insufficient

second, the competitiveness of products is weak. The advantage of China's internal combustion engine industry lies in the field of diesel engines for heavy vehicles, while the power for light vehicles and non road mobile machinery is in a weak position. Gasoline engines for passenger vehicles have no overall strength, no voice, let alone advantages

third, China's internal combustion engine industry has no other characteristics except large production capacity in the global internal combustion engine manufacturing market dominated by the Americas (mainly North America), Europe and East Asia (Japan and South Korea)

among them, the regional scale is not prominent and has no characteristics. Apart from the agricultural single cylinder diesel engine dominated by Changzhou, which enjoys a certain reputation in Asia, there are no regional brands in the fields of vehicle, engineering machinery, agricultural machinery and so on, especially in the multi cylinder engine industry; There is no advantageous scale of the group and no team size driven by the brand

fourth, the basic parts industry is still messy, mainly manifested in: there are few advantageous enterprises in parts manufacturing, and the foundation of independent research and development is weak; The joint-venture brands of component manufacturing enterprises are dominant, and the phenomenon of losing the right to speak is particularly prominent; The fuel system manufacturing enterprises of spark ignition and compression ignition internal combustion engines are facing the monopoly and competition of internationally renowned enterprises in the domestic market, and Chinese enterprises have no technological advantages

fifth, the pressure of environmental protection increases. The carbon dioxide emitted by transportation, agriculture and industrial machinery mainly powered by internal combustion engines accounts for a large proportion of the overall environmental emissions, which is directly related to the sharp increase in vehicle production and ownership. 12% of the carbon dioxide in the atmosphere comes from vehicle exhaust emissions (without considering the emissions of internal combustion engines such as industry/Agriculture/other transportation)

in addition, the emission pollution of diesel engines for non road mobile machinery in China can not be ignored. China is not only a large automobile production country, but also a large non road mobile machinery production and consumption country. According to the recent statistics of the State Environmental Protection Administration, the particulate (PM) and nitrogen oxide (NOx) emissions of non road mobile mechanical engines in China account for 61% and 42.2% of the total mobile emission sources of the whole input equipment, respectively. The emissions of carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulates (PM) from agricultural machinery and agricultural transport vehicles account for 89.7%, 89.8%, 71.8% and 87.5% of the emissions from non road mobile machinery, respectively

sixth, from the perspective of energy supply, there is an urgent need for energy-saving products. Since 2000, the annual consumption of gasoline and diesel oil in automobiles (including low-speed trucks) has accounted for more than 50% of China's total oil consumption. In view of the increasingly severe environmental protection and energy pressure, the Chinese government has specially formulated the "China's national plan for coping with climate change", and energy conservation and emission reduction has become China's basic choice to preserve the path of national policy

China proposed in the "Eleventh Five Year Plan" for automobile development that by 2010, the average fuel consumption per 100 kilometers of new vehicles will be reduced by 15% compared with that in 2005

the national medium and long term science and technology development plan (2006-2020) places the development of low-energy and new energy vehicles in an important position; It is required to focus on the research and development of hybrid electric vehicles, alternative fuel vehicles and fuel cell vehicles, vehicle design, integration and manufacturing technology, powertrain integration and control technology, automotive computing platform technology, efficient and low emission internal combustion engines, fuel cell engines, power batteries, drive motors and other key component technologies

from the perspective of the development of internal combustion engine industry in advanced countries in the world, the internal combustion engine industry in advanced countries has entered an era of high-tech, high investment and high output. Once deposited through continuous nozzles, multinational companies mostly use global resources to develop and expand themselves. The speed of new product development, product performance, brand, quality, cost and after-sales service have become the decisive factors for the success or failure of international internal combustion engine enterprises. At present, there is a big gap between China's internal combustion engine industry and multinational companies, which faces severe challenges
