The responsibility of the government
In response to the Euro IV concept that China has just begun to pay attention to, Ni Hongjie, chairman of the China Internal Combustion Engine Industry Association, said in an interview with reporters that heavy-duty diesel engines have to achieve Euro IV emissions. There are two mature technology routes worldwide, one is SCR (selectivity Catalytic reduction) post-processing technology, the second is through the use of EGR (exhaust gas recirculation) in front of the engine, particulate traps in the post-processing part, particles are filtered through the filter before burning to reduce pollution. Both methods have advantages and disadvantages. However, due to the simplicity of the SCR post-processing technology and minor changes, the European IV standard can be achieved by adding appropriate post-processing on the Euro III model. There are no stringent requirements for oil quality such as sulphur content, and many companies are more demanding. Look for the technology. Ni Hongjie believes that if an SCR post-processing system is used, gas stations in all parts of the country must be equipped with ammonia-added equipment. When the equipment is built and by whom, it is a major problem. It is not simply petroleum or petrochemical, but involves many departments. He said, “The state will implement the emission of State IV or even higher later. This is a systematic project and it is necessary to comprehensively integrate and coordinate the various departments to consider. In particular, the National Development and Reform Commission shall comprehensively coordinate and consider the specific implementation issues as soon as possible.â€
In the United States, Europe, Japan, and other places, the national environmental protection department does not make demands on whether the new cars are delivered or not. They check whether the discharge of the vehicles in use is in compliance with the standards after five or even ten years of operation. If the standards are not met, the automobile factory will have to pay a large fine. The penalty is so great that the automobile factory feels that it is not only necessary to ensure that the new vehicle comes out of the discharge standard, but also that it meets the requirements for the entire life cycle of the vehicle. Dr. Zhan Rijing, of the Institute for Engines, Emissions, and Vehicles of the Southwest Research Institute of the United States, who is familiar with such emissions monitoring and oversight mechanisms abroad, told reporters that the key to the implementation of China III and IV emission standards in the future is whether regulations are implemented and engine emissions are met. Requirements, how to detect, who will detect, test unqualified how to do and so on. In addition, emissions testing is not directed to the new vehicle, but whether it can maintain the national III and IV emission requirements of the vehicle throughout its service life. At present, not only does the detection technology in this area need to be further improved, but also there is no corresponding incentive, punishment, and supervision mechanism.
Yan Hui, a representative of Mann's Commercial Vehicle Management (Beijing) Co., Ltd., said that now the developed countries are shutting out Chinese cars through leading emission standards, so China should be in line with the world as soon as possible in its emission regulations. In order for the Chinese auto industry to truly take off, all large and medium-sized state-owned and private auto companies must develop. In addition, from the government level, the government must strengthen the seriousness and rationality of policy formulation. For example, in the past, restrictions on diesel engines, discrimination against small-displacement vehicles, etc., now everyone has gradually realized that whether it is a gasoline engine or a diesel engine, it can be accepted and recognized as long as it meets the requirements of emission regulations. Living space; The fuel economy, economy, and environmental protection of small-displacement vehicles are gradually gaining recognition. Ordinary consumers have a process of understanding new things. The government must first be clear-headed. It should also have such a sense of responsibility. On the one hand, it guides consumption and on the other hand, it makes reasonable game rules. Yan Hui believes that if these three aspects are combined well, the time for the Chinese automobile industry to surpass the West should be within the next 10 to 15 years.
Gasoline engine lags behind diesel engine
The biggest regret that many internal combustion engine manufacturers feel at this exhibition is that there are too few host companies participating in the exhibition. It is generally believed that the technical level of domestic gasoline engines is even behind that of diesel engines. Nie Tianfei, Sales Director of Lotus Automotive Technology Engineering North District, said that gasoline engines and small diesel engines are fitted on passenger cars and small passenger vehicles. The requirements for noise, emissions, and fuel consumption are all very high. In contrast, diesel engines, especially heavy-duty diesel engines, require simpler noise, vibration, and technology. Lotus Automotive Technology began developing Euro IV emission standards in 1990. However, China has only recently reached Euro II in diesel engines, and gasoline engines have reached Euro III. The gap is very large. Both in the design and component factors, such as foundries, engine management system suppliers, component suppliers, etc. that meet the requirements, these can not meet the requirements. Most of the domestic companies that can meet the requirements are the engines of the joint venture. Their main task is to supply the joint venture vehicle manufacturers.
Mann's Yan Hui believes that the key to the gap lies in R&D accumulation and R&D investment. Compared with 10% or even 20% of sales revenues invested by many foreign companies each year, local companies generally have little investment in R&D. Such as materials, domestic generally use ductile iron materials, the cylinder must reach a certain thickness to meet the high strength requirements. This makes the engine very bulky and does not look compact. However, MAN's best engine block uses a very special vermicular cast iron material, which can reduce the thickness of the cylinder body and achieve a lightweight design. In addition, there are certain gaps in domestic corrosion resistance and heat resistance like other related technologies such as rubber, plastics, and seals.
Dr. Zhan Rijing of the Southwest Research Institute of the United States said that currently domestic diesel engines in China are generally jointly developed with foreign countries, while gasoline engines are mostly copied from abroad, which also causes gasoline engines to lag behind diesel engines. He believes that companies such as Chery and Geely have a unique ability to independently develop gasoline engines. This is a very good direction. “I feel that Chery Automobile should be able to export to the US market in 2008 or 2009. Although people may now question its quality, the development is facing the future, just as it was when South Korea Hyundai was mocked in the United States 10 years ago, but now Its quality is enough to make Ford and GM feel great threats. I believe that the Chinese car exported to the US market after 10 years will have a price/performance ratio that will make Toyota, Honda and Hyundai worried."
Yan Hui agrees with this: “The level of technology in China’s autos needs to really go up, it still depends on large companies such as FAW, Dongfeng , CNHTC and Chery. Like Chery’s now mostly low-end vehicles, the key is that it is already Gradually occupy the market share, large companies have the technology, talent accumulation and financial strength, have market advantages, new products in addition to bench, road test experiment, many new technologies to pass the market verification, a large number of models sold by enterprises are often in practical use Feedback on a lot of product improvement information.I think that the next national support will focus on the national automotive industry. After all, large state-owned enterprise countries such as FAW and Dongfeng have already 'passed their blood' and have grown and entered a virtuous cycle. Track, it is difficult for others to shake their dominant position."
Professionals flow to China
Dr. Yuanxian Zhu, Chief Technical Officer of Chengdu Witt Electronic Spray Co., Ltd. has had experience working in the United States. After returning home, he joined Chengdu Witt and led the development of the engine electronic control system in China. The technical backbones of a large number of overseas large enterprise groups such as these have returned home or created R&D companies or joined domestic companies to develop core electronic control systems, which has greatly boosted the level of Chinese domestic engine technology.
The related person of this Delphi Automotive Systems (China) Investment Co., Ltd. said that if we use Korea as a mirror for technology development, we must first be a student. Foreign companies invest in China and recruit Chinese personnel. Although they can't see results now, but as Chinese people have accumulated more and more technology, knowledge, and ideas, some will go out and set up R&D companies themselves, or join local companies to lead China’s own R & D, this requires a process. Now that Konka and BYD have been involved in the automotive ECU controller field in the south, their R&D personnel are basically the technical backbone of world-class companies such as Motorola. This approach can be extended to all parts of the car. The flow of talents and frequent technical exchanges between China and foreign countries have gradually brought domestic and foreign technology levels closer. With the development of the automobile industry, China will keep up, even surpass the West, and this day will come.
