Under the pressure of environmental protection, cars are listed as one of the chief culprit of air pollution. Although the contribution rate of cars to smog is still a controversial topic, the control of automobile exhaust has become a full pollution of air. The consensus of the society, in the development of the automobile industry in China in just a few decades, to catch up with the automobile emission and fuel consumption limits of some countries in Europe and America in the state of accelerating the running. Such catching is a last resort for the people. For this reason, for the enterprise, it is a risk to survive and bear the dual pressure of responsibility. However, when China’s automobile emission standards have ushered in the country V and go to the country VI, when we want to look up slightly, look at the road again. When we look at whether the direction of catching up is still in line with the actual situation in our country, we are indeed somewhat confused. I don’t know how to go this route is really practical and feasible. If nothing is done, it should be calm and serious. Discussion and research, whether it is a company, an industry expert or a research institution, there must be a state in which it is placed.

The difficulty of the Sixth Route is undeniable. China's auto industry started late. Many relevant laws and regulations are based on the experience of foreign developed countries. This kind of development method of learning while learning has been promoting the rapid development of China's auto industry for a long period of time. Development has played a key role. However, as China's automobile industry develops in depth, it has also exposed some problems, especially the current increase in air pollution, raising the society's attention to vehicle emissions and fuel limits to an unprecedented height. Under such circumstances, the automotive industry is also aware of some problems existing in the current emission standards, such as not meeting the actual working conditions in China, the actual emission value is higher than the standard requirements, lack of supervision and monitoring during the use of vehicles, etc. So, I began to explore how the next country VI should go. As the saying goes, it is hard to return. After all, from country I to country V is not a very short time, and I have never thought about change. Now even if it is time to seriously think about it, seek for change. At the time, it is difficult to achieve the desired state at a glance. Is it a small step or a big step, is it cautious and steady? At present, the route of the National VI has reached a time when it has to be studied seriously.
Follow the European standard or change the American standard?
At present, the world's automobile emission standards stand side by side and are divided into three major systems: Europe, the United States, and Japan. The European standard test requirements are relatively broad, and are the automobile exhaust emission systems most commonly used in developing countries, while Japan and the United States are the most stringent. Most of China's autos introduce production technology from Europe, so they generally adopt the European standard system, and their exhaust emission standards are extended to the European standard system. However, with the increasing smog problem in China in the past two years, at the national level, for the sake of people's livelihood, it is intended to implement stricter standards on automobile emissions, so whether to continue to use the European standard for a long time, disputes can not be disputed. .
The dispute began in September 2013, a green traffic news conference held at the Clean Air Initiative in Beijing. At the meeting, Li Kunsheng, Director of the Motor Vehicle Division of the Beijing Municipal Environmental Protection Bureau, said: “The fifth stage emission standard currently used is gasoline. The standard of the car is 60 mg per kilometer of nitrogen oxides, and the indicator to the Euro 6 standard is still 60 mg. The standard for gasoline vehicles is not tightened, so in the sixth stage we want to refer to the California standard." As soon as it came out, the topic that Guoliu would abandon the European standard with the American standard has attracted wide attention in the automotive industry. For this proposal, Li Kunsheng believes that the pollution situation in Beijing is more serious than California under certain circumstances. As the most strict area for controlling motor vehicles in the world, California's standards are stricter than those of Europe, which is the EPA's desire to adopt California standards. The original intention.
Due to environmental considerations, it is understandable that the emission standards are tightened. It is reasonable to assume that the automobile production enterprises should also bear a responsibility and obligation for the overall living environment of China, but the enterprises also have the difficulties of the enterprises. After all, the adjustment of the standard technical routes It will directly affect the interests of vehicle and component companies. Therefore, companies have expressed a more cautious attitude toward changes in standards.
Zhang Weidong, assistant general manager of Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., Ltd. said that from the fourth country to the fifth country, since the route of emission standards has been consistent with the previous one, there is not much problem for the joint venture or the independent enterprise. However, if the technical route of Guoliu is to be adjusted, the independent brand will put forward higher requirements on the consistency and reliability of product technology, and the independent brand will face greater pressure, especially in terms of cost. Increase. As a result, the cost increase is too much to sell, and the impact is immeasurable. After all, many Chinese car companies are pillar enterprises in various places, and their business conditions and logistics, supporting facilities, tertiary products, social services, etc. All walks of life are related to each other, and may eventually bring about certain social problems and affect the harmony and stability of the whole society.
Long Yongsheng, chief engineer of Dongfeng Motor Technology Center, said that most countries in the world still take the European standard route. The US standard is only used in the United States and some North American countries. If we follow the American standard, we will export the cars to foreign countries. It is very difficult to redesign and develop a product that meets the European standard. Therefore, if Beijing Six wants to be stricter, it can raise the limit on the existing European standard. It is not a new standard to be re-started. It should be suitable for the specific situation of China.
Set a Chinese own standard?
In the end, whether it is the continuation of the European standard or the change of the US standard, there is a more powerful voice that China has its own national conditions and the background of implementing emission standards is different from that of Europe. It is the difference between urban and rural areas, so China should have its own standards. Dr. Zhan Rijing, the chief engineer of the Southwest Research Institute of the United States, once said that there are only three emission systems in Europe, the United States and Japan in the world. When we have vowed to build a car powerhouse, especially if China has become the world's largest automobile manufacturing and consumer market, have you ever thought about adding China to the list of world emission systems?
Establishing China's own emission standards, ambition is commendable, but the achievability and operability, the industry has expressed a different view. Zhou Zhongguang, the director of the research and development department of Chery Automobile Co., Ltd., said that our country should be based on the strengths of each family, find a good idea, a route that suits oneself, and do it in a down-to-earth manner. In terms of the long-term development of enterprises, it is very meaningful, because enterprises must strengthen their competitiveness while being in line with international standards.
Long Yongsheng, chief engineer of Dongfeng Motor Technology Center, expressed similar views. He said that traditionally, China has made reference to the European standard in formulating emission standards. Now, since we are discussing this standard, it is It is not possible to refer to the Chinese cycle and make a standard of its own. Don't just use the standards of others, we will make our own standards. In this way, if foreign automobile products are to be sold to the Chinese market, they must follow our standards, which will also promote the development of independent brands.
Zhang Weidong, assistant general manager of Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., Ltd., expressed different views. He said that we must be China's own emission standards for China's situation. So what level can we do? It’s not really new. What is the meaning of the question is a question that deserves to be discussed. If you want to do it, you have to know what our goal is, is it to surpass Europe or exceed the United States? Even if the target is set, how much feasibility will it be from the current technical level of Chinese companies? Therefore, all aspects need to be further explored.
The implementation time dispute In addition to the technical disputes that the country should take in the industry, another controversial issue is the implementation time of the country. All along, China has basically followed the three-year standard change interval from the first country to the country five, which is basically consistent with the European standard's replacement time. However, under the current pressure of environmental protection, the implementation of Guoliu is not only considering the transformation of the technical route, but also intends to achieve it faster in time, especially the Beijing-Beijing standard. It is said that it will be implemented in 2016, which makes the enterprise Feel the pressure that has never been seen before. Therefore, the specific time for the implementation of the country's six has become the top priority of all enterprises.
When Zhou Zhongguang, the director of the research and development department of Chery Automobile Co., Ltd., said that he was most concerned about the issues of greatest concern, he was most concerned about the implementation time of the National Sixth. At the same time as setting the target as soon as possible, he must do a full investigation and leave it to The company must reflect the time and a certain development cycle.
Zhang Weidong, assistant general manager of Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., Ltd., believes that if Beijing can implement the national six in 2016, it depends on what kind of technical route Beijing wants to take. If it still continues the old habit, refer to the European six, and It can be realized, but if you change the route and add the reference factor of American Standard, it will be difficult to implement. After all, the company has always been the old route in the technical reserve. If you want to make major changes, it will involve how to detect, how the software changes, how the personnel operate, and the inspection department and the enterprise inspection personnel must conduct training for a certain period of time. The series of problems; secondly, the problem of detecting equipment differences, the increase of corporate investment costs, etc. can not be solved in a short period of time, so that Beijing Six is ​​also good for the country, its implementation time should be linked to the technical route, must Careful consideration must not be made in order to pursue the speed of the final standard.
Long Yongsheng, chief engineer of Dongfeng Motor Technology Center, said that the country should implement the national five in 2018, and Beijing should not advance the country several levels. The country enters the country five, and Beijing enters the country six is ​​still relatively reasonable. According to foreign experience, three years and one cycle In 2018, Beijing’s entry into the country is still relatively reasonable. There are a lot of standards to improve in a short period of time, and it can only force the US suppliers to recruit and copy other people's technology. In addition, he also analyzed the problem that the implementation time of the country should not be too fast. He said that it takes about three years to develop a product and the life cycle is five years. So we said that an engine and a car are coming out. It takes ten years to calculate according to such a life cycle, otherwise the cost will be difficult to close, and the enterprise is losing money. Europe is also three or four years from the fourth to the fifth. Therefore, if we are going to introduce Jingliu in 2016, we feel that it is still too fast and not realistic.
From the point of view of the above-mentioned business people, everyone is recognized for the tightening of standards, and it is also consistent that environmental protection is necessary. However, as a business, it is more important to pay attention to the issue of survival and development. If the implementation of a standard causes the cost of the enterprise to be too high, it will make consumers unacceptable. Therefore, as a company, although it agrees to implement higher standards, it still hopes to push it forward at the time node. However, what kind of time is reasonable, and it is necessary to conduct a large number of market research. Make reasonable inferences based on the basis.
The mystery of the national attitude was learned during the interview process of the reporter. In addition to the technical route and implementation time, the key to the implementation of the national six is ​​the attitude of the state. In the end, is the country determined to rectify air pollution as the top priority, or should we consider the long-term development of China's automobile industry in terms of pollution control and adopt relatively moderate development measures? The difference between these two attitudes will lead to very different results.
Zhang Weidong, assistant general manager of Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., Ltd. believes that industrial integration and survival of the fittest are laws of development. However, if it is too radical, it will lead to a growing market share of foreign capital and joint ventures, and the independent development space will gradually be affected. Squeeze, so it depends on how the government considers it. If the government puts environmental issues first, let’s not say how much the car’s emissions contribute to air pollution. If it is harmful to the environment, it must be managed. Very strict requirements are imposed on emission standards. Just as it is said now that reforms should be carried out on the technical route. If this becomes a reality, many independent enterprises will withdraw from the market after 2018. In the final analysis, what is the government’s approach to independent brands? Is the attitude supported or allowed to be self-defeating? In fact, the state can give certain financial support to independent enterprises while the standards are tightened. For example, the establishment of development funds to encourage technology development, so that the development of independent enterprises will not be severely suppressed.
The author thinks that it is very important for the country to control the air pollution to give the people a fresh and comfortable living environment. This is related to the health status of the people of the whole country and the happiness index of life. However, for enterprises, survival must also be considered. The first priority is that these development problems facing China are inevitable in the development process. What is important now is not the question of choice and abandonment. What kind of strategy should be taken is the most important issue to be explored.
If the problem is encountered in the period of the survey, it needs to be discussed. It is necessary to explore the feasibility of incorporating the US and California emission standards based on China's automobile market and atmospheric environmental management based on sufficient research. According to the development status of the industry, the Ministry of Environmental Protection is proposed to formulate new emission standards, especially in the adaptation and implementation methods and time of emission standards in Europe and the United States. The China Automotive Technology and Research Center has set up a research team for the National Sixth Project, and strives to achieve the following objectives in the research process: 1. Grasp the trends and development trends of the motor vehicle country 5 and the national 6 emission standards, and analyze the standards and regulations for motor vehicle emission control. Environment; 2. Compare internationally advanced emission standards, especially European emission standards and US and California emission standards in terms of emission limits, test conditions, fuel quality, etc., and explore emission standards that are suitable for China's national conditions; The automakers and engine plants conducted research to summarize the current major technologies and product reserves in the market to meet the national five emissions, explore the technical route of the national six emission control, and summarize the main technical problems and challenges.
For the research and discussion of the research group, the company also showed great interest and put forward many useful suggestions. Hong Bochang, Minister of Development Planning Department of Kunming Yunnei Power Co., Ltd. proposed that in the case of automobile emissions, the current situation in China is different from that in foreign countries. Foreign countries have begun to implement the sixth stage standard. Foreign countries are now our future, foreign countries. How to do policies, product announcements, and supporting, we need to have sufficient research to better learn from experience.
Song Qingyuan, director of the Engineering Research Institute of Beiqi Foton Motor Co., Ltd., believes that whether the research is domestic or foreign, the purpose is to provide practical and theoretical support, and the regulations must conform to the industrial status and emission status. We must understand why there is such a big difference between Europe and the United States in terms of emission standards. In fact, they are all in order to protect their industrial base. Therefore, our research should also fully consider the protection of China's industrial development.
Zhu Hang, assistant general manager of Chery Automobile Co., Ltd., said that regulations, limits, test conditions, etc. should give a complete and comprehensive plan, not only to introduce technical solutions, but also to introduce how to introduce each stage, especially in the face of cost issues. How to digest the enterprise, how to introduce the society, how to build it, etc. should conduct sufficient research and give reasonable suggestions.
......
In addition, for the implementation of the national six implementation time issues, post-processing technical analysis issues, oil quality issues, and other representatives of the enterprises have raised some questions, given some suggestions, expressed some expectations ... corporate enthusiasm represents the company The focus of the implementation of emission standards, and the establishment of the China Automotive Technology and Research Center is also expected to provide more operational recommendations for the implementation of future emission standards in China through adequate market research. The significance of the research is self-evident. Of course, this kind of enterprise and scientific research institutions are working together to contribute to the healthy development of China's automobile industry. It also makes us feel gratified and expects real and effective research results to put forward practical standards for China's automobile emissions. References.
