Due to China's unique national conditions, vast territory and large population base, along with the flow of social population, the automotive industry has rapidly emerged. The data shows that in 2013, the sales volume of new cars in China exceeded the 20 million mark for the first time. In addition to coastal areas such as Shanghai, the demand for new cars in inland areas is also expanding, and about one-fourth of the world's new car sales are concentrated in China. Today, not only in Asia and Africa and other continents, including Europe, North America and other places, can see the Chinese car brand figure. Now, our country deserves to be a big automobile producer. This point has also been recognized by many experts and scholars.
On April 20, 2014, at the “International Symposium on Reliability Technology of Internal Combustion Engines†held in Beijing, Zhang Qing, vice president of the Chongqing Changan Automobile Co., Ltd. Power Research Institute, stated that China is a veritable automobile production country, but this Behind the name, it is hard to avoid the shadow of "rough management."
Enhance reliability standards, bid farewell to "run rough" Time <br> <br> how to understand the "rough business" mean? Zhang Qing explained to passenger cars, for example, the current production of passenger cars and related spare parts has their own standards But first of all, these standards are difficult to unify and chaotic. Nowadays, the competition of automobiles and parts can be said to be standard competition. If the consistency of parts suppliers is not good enough, the problem of increasing the failure rate is difficult to avoid. If the standard is not uniform, the failure will be more divergent. Form a unified approach and approach. Second, some standards, such as the national standards for vehicle reliability, are somewhat lower than the foreign passenger car industry standards, and there is even a gap between the standards implemented by domestic joint ventures. This will inevitably lead to the first failure mileage and the average failure interval is low, although to meet the relevant national standards, but not meet the market competition and increasing user demand.
The lack of a unified standard will inevitably lead to the status of "passive assault" in the international trade friction of China's entire vehicle and parts and components companies. Even in the domestic market, as the demand of market users continues to increase, the requirements will also increase. The long-term confusion will also lead to the degradation of the performance indicators of the entire vehicle and parts, and ultimately reduce the user satisfaction.
In response, Zhao Weidong, general manager of Shandong Xinya Industrial Co., Ltd., also stated that the key issues facing the reliability of the entire vehicle and parts industry in China are the inconsistency of standards and the non-standard implementation of processes. Zhao Weidong suggested that in the development of products, each vehicle and component company should first determine the reliability goal at the initial stage of product design. The target must be based on the needs of the market users, but also reference standards for competitors, so it is often higher than the current national industry standards. After determining the reliability goals, all R&D, design, and production processes should be centered around this reliability goal.
In addition, for the reliability test of the product, Zhang Qing stated that it should not be applied only to the entire vehicle and the whole machine field. Before the complete vehicle reliability test, the reliability test verification of the component system should be strengthened only when the total number of components After the reliability test is passed, the loading test is carried out again. At the same time, improve the vehicle's complete machine reliability test assessment standards, user requirements and the reliability indicators of the benchmark joint venture brand, to determine a more qualified test standards higher than the national standard. Among these, industry associations should play their own role and fully promote the establishment and implementation of standards.
Engine reliability and energy conservation relations <br> <br> technology as the driving force of the heart and core of the vehicle, the establishment of a unified internal combustion engine and reliability standards in the field of spare parts should be focused on is treated. At present, the application of environmental protection and clean energy power has gradually become the development trend of the future power market. Especially in 2013, the General Office of the State Council issued the “Opinions on Strengthening the Energy-saving and Emission Reduction of the Internal-combustion Engine Industry†to examine the energy-saving and emission reduction of the entire internal combustion engine industry. Countdown started. All this seems to have made the development of traditional internal combustion engines "necessary." Actually, according to official statistics, traditional engines will still dominate the next 10 years; traditional engines will account for 54% in the next 20 years, hybrid engines will account for 30%, and fuel cells will account for 1%; engines and hybrids will still occupy 70 in the next 40 years. % more than the market. Therefore, for a long period of time in the future, not only can we not abandon the R&D and use of conventional internal combustion engines, but we should also pay more attention to the energy saving and environmental protection features of internal combustion engines.
What is the relationship between the requirements for energy saving and environmental protection in the future development of internal combustion engines and the reliability of internal combustion engines? On this issue, Lu Zhuohua, deputy general manager of deputy general manager of Dongfeng Cummins Engine Co., Ltd., said: “Energy saving and emission reduction requirements increase the combustion efficiency of the engine. , Cylinder pressure, heat load, injection pressure, and resistance to combustion corrosion products are all challenges to the reliability of the internal combustion engine, requiring the internal combustion engine in the development process, new material applications, parts tolerance, high mechanical load, The heat load, friction and wear ability have greatly improved."
"But at the same time, a more reliable and durable engine can greatly extend the life and durability of the engine, reduce the need for energy materials in repairing, scrapping, remanufacturing, and even purchasing new engines, while reducing the deterioration of engine use. The emission pollution comes from, "Lu Zhuohua said, "Energy saving and emission reduction are both challenges to the reliability of the internal combustion engine, and they also complement each other."
The technical foundation of key technologies and key components of internal combustion engine products in our country is weak and the core technology is missing. This is a recognized "hard injury". The energy-saving, emission-reduction and reliability of internal combustion engines are related to technological capabilities and involve the upgrading of the entire power system. In these aspects, foreign-funded enterprises can be said to have more advantages. Taking Cummins as an example, the most important reason why the company can succeed is technology leadership. It is understood that Cummins has four major technology research and development centers in the world, and the investment in technology research and development every day is more than 2 million US dollars. It can be said that Cummins's emphasis on technology has made it a leader in the industry. This also made a good demonstration for domestic related companies.
Since the development of internal combustion engines today, energy conservation and environmental protection have become the theme of their development, and the most important obstacle is still technical factors. In response to these problems, the experts attending the meeting, on the premise that enterprises can give full attention to them, also called on relevant departments to quickly implement industry-related guidelines, regulate the implementation of various technical regulations, emission standards, and other policies, and encourage the adoption of internationally advanced technologies. The scientific and technological line of technology, unification and upgrading of industry standards can effectively promote the development of our internal combustion engine industry.
The "International Symposium on Reliability of Internal Combustion Engines" was held on April 20th, 2014 in Beijing. It was sponsored by the Automobile Engine Branch of the China Association of Automobile Manufacturers, co-organized by the IC Reliability Innovation International Alliance and Shandong Provincial Key Laboratory of Engine Reliability. .
