Diesel engine enters the country four times opens up 100 billion after processing market
The diesel engine industry entered the four times of the country. The reporter learned from the Ministry of environmental protection that since July 1st, China has implemented the fourth stage emission standard for light vehicles nationwide, and the light vehicles that have not reached the national four emission standards will not be able to enter the new car announcement of the Ministry of industry and information. Starting next July 1st, light duty vehicles that do not meet the national four emission standards nationwide will not be sold and registered. At the same time, the Ministry of environmental protection has stopped approving the three heavy-duty vehicles in January 1st this year according to the national emission standards.
Post processing technology is the focus
Hong Jianhua, Secretary General of the Specialized Committee after the emission of internal combustion engines, told reporters: "from two to three countries, the key is the fuel injection system, and from three to four of the country, it is necessary to use post treatment technology."
In the middle of last century, with the continuous improvement of vehicle environmental standards, the emission post processing industry rose rapidly in Europe and America. At the end of 2006, the three companies of Volkswagen, Audi and Mercedes Benz jointly launched bluetec technology, which caused a great sensation in the world. Bluetec is an advanced post processing technology. According to the statistics of the US environmental protection department, diesel engine uses bluetec to reduce the emission of particles by 98% and reduce the emission of harmful gas by 80%.
In recent years, China's internal combustion engine manufacturing enterprises have made little progress, but in the development of engine products, there is a big gap with foreign countries, and the post processing industry has just started.
China's huge market attracts world-renowned internal combustion engine research institutes to enter China. After AVL and FEV, the Southwest Institute of the United States, the British lotus, Czech AI Kodak, Australia Australia Beto, and Austria Eli have also recently entered the Chinese market. For example, the German BASF has established a wholly owned subsidiary in Shanghai, and the four Cummins engine of the Beijing bus assembly is the SCR (Selective Reduction Catalysis) provided by BASF.
"These companies cooperate with Chinese enterprises in developing new products, and recommend the selection, matching and purchasing of post-processing equipment. If China does not develop its own emissions reprocessing manufacturing industry, it is likely to become the market for foreign sales of emissions reprocessing products to maximize profits. Ni Hongjie, honorary director of the China internal combustion engine industry association, said.
"At present, the European Post emissions processing industry has an output value of about 80 billion yuan. According to China's car ownership, after the implementation of the four national standards, the post-treatment industry will have a market share of hundreds of billions of dollars. "The profit of diesel engine after-treatment is very rich, which attracts the attention of multinational corporations," said a person from China Automobile Industry Association.
Domestic enterprises are also developing diesel engine aftertreatment products, these enterprises are mainly some of the original gasoline engine aftertreatment system suppliers. It is understood that at present, several key enterprises of diesel engine post processing system have been formed in China, including Wuxi Wei Fu Da catalytic purifier Co., Ltd., Sichuan self exhaust purification company and Kunming Guiyan catalyst company.
"We mainly produce tail gas reprocessing catalyst, which was put into research and development in 2005. At present, we are cooperating with many domestic diesel engine manufacturers." Chen Qizhang, general manager of Sichuan self purification company, said. "There are not many enterprises that can provide mature products in China, and there is a big gap between them."
Market selection SCR Technology
According to the introduction, at present, the international internal combustion engine industry has developed from Europe III to Euro IV, and there are two basic systems. In general, Europe tends to use the SCR (selective catalytic reduction) system to treat the nitrogen oxides in the tail gas by urea solution; the United States and Japan tend to EGR (exhaust gas recirculation) system, that is, the EGR (exhaust gas) that is treated by a particle trap or a particle catalytic converter (DPF) for the combustion of the particles produced by the combustion. Recirculation) technology. Because of different national conditions, enterprises in different countries have different inclination to choose technology.
According to the reporter, in the technical line, the domestic mainstream diesel engine production enterprises have basically reached a consensus, SCR will be the main technical direction of diesel engine emission upgrading in the future. At present, Cummings, Weichai, Yuchai and so on all adopt the SCR technology.
Analysts attribute the reasons why SCR systems are more suitable for the Chinese market to the following aspects: First, SCR systems can effectively save fuel consumption. The fuel consumption of SCR system is slightly lower than that of EGR + DPF system, and the consumption of urea solution can be compensated in fuel consumption. Second, if this technology is adopted now, it will be able to meet the requirements of emission regulations for a long time, until the introduction of Euro V and even higher emission standards. Third, in the e + + D - F system, the volume of the cooler needs to be increased. The SCR system needs only one additional storage tank, which has little impact on the design of the vehicle cab. Fourth, the complexity of the engine is low. The SCR system can meet the three and four national standards at the same time, and can be introduced in some areas in advance.
In the face of the coming four emission standards, domestic enterprises are already prepared. Yulai machine Limited by Share Ltd chairman of the senior technical consultant Dr. Li Qin said: "the mainstream of domestic enterprises are basically the development of SCR products, but the official batch production is only the jade Chai family."
The advantage of Yuchai's first hair is the formation of the market. Because the SCR post-processing system market is relatively concentrated, basically in the city bus, and Yuchai customers just concentrated in the field of bus. As early as 2006, Yulai introduced China's first four diesel engine with independent intellectual property rights, which was 5 years ahead of the national compulsory four emission standard.
