According to the requirements of the National Development and Reform Commission and the Ministry of Environmental Protection, starting from July 1, the Ministry of Public Security will not register licenses for vehicles that do not meet the National III standards, which means that the full implementation of the National III standards is imminent.
In the face of the implementation of the new standard, many domestic commercial vehicle manufacturers have already fully prepared. The reporter learned from the Changan Automobile Group that Changan’s commercial models have adopted mature technology and have met the country’s three emission standards. “We started the relevant preparations from the end of 2007 and have completely stopped the production of the standard cars of the second country in March of this year.â€
Zhu Huarong, vice president of Changan Automobile Group, told reporters, "So we have done a very good program in the production of models."
It is reported that due to the imperative of implementation of the National Three Standards, many domestic companies that produce commercial vehicles such as Dongfeng, Beiqi Foton, China National Heavy Duty Truck, First Automobile Group, Nanjing Iveco, Jiangling Motors, etc. have adopted various forms in the emission of vehicles. The technical solution has met the requirements of the emission standards. Dongfeng Company has successively introduced Dongfeng Tianlong series models, Dongfeng truck type and Dongfeng light truck series models that meet the national three standards in the field of commercial vehicles.
The implementation of the three national standards is no longer a problem for cars using gasoline; however, this will be a major test for many domestic commercial vehicles that use diesel engines. Due to technical reasons, it is difficult for domestic manufacturers of commercial vehicles to meet relevant standards through their own technical level.
For commercial vehicles using diesel engines, the key to achieving this standard is to reduce the nitrogen oxide content in the exhaust gas, and the most direct and effective way is to delay the engine's fuel supply time. However, after the oil supply is postponed, the maximum combustion temperature in the engine will be reduced, the efficiency of work will be reduced accordingly, and the fuel consumption will naturally increase. To solve this series of problems, we must adopt electronically controlled fuel injection technology, which is a major technical barrier for domestic car companies. Currently only Bosch, Denso, Delphi and other professional parts and components companies are leading in this field.
In order to achieve the country's three emission standards to be implemented, domestic automobile enterprises have adopted advanced foreign technologies. Zhao Jingguang, spokesperson of Beiqi Foton Motor, said: “Our model has reached the national emission standard, and the country’s second model is no longer in production. Technically, we use a method that matches foreign technology, which is more conducive to vehicle models. "The competitiveness of the company." "Dongfeng Automobile" deputy general manager Lu Feng also said, "At present, 'Dongfeng Motor' in the diesel engine and the National Development and Reform Commission announced the Yunnei power, Chaochai, Yuchai three engine companies have adopted cooperation, which The diesel engines produced by the three companies also take the form of introducing, digesting, and absorbing foreign technologies."
Senior automotive industry analyst Jia Xinguang believes that the implementation of the country's three emission standards is conducive to the country to complete the automotive industry upgrade, but also put forward higher requirements for the domestic commercial vehicle industry. "The improvement of emission standards will, from an industrial perspective, promote more manufacturers to participate in the corresponding technology research and development."
Some analysts believe that due to the use of foreign technology, will lead to future commercial vehicle companies rely heavily on foreign technology in diesel engines, thus further forming the company's inert demand in research and development. Perhaps in the future, after the formation of a monopoly of foreign technology, it will have a wider negative impact on domestic models.
“Now many commercial vehicle manufacturers in China have not really developed the corresponding technologies. They are a kind of adoptive attitude and have lost their true self-development capabilities. Currently, only three national standards have been implemented, and other countries will implement future national or even national regulations. In the five standards, these enterprises will still face such technical barriers. Therefore, for the development of enterprises, it is necessary to have a long-term strategic awareness, and building up their own technical reserves is the real development path.†While worrying, Jia Xinguang also stated that “for domestic companies, R&D still requires certain market support and environmental support.â€
Analysts pointed out that whether it is the current state of the three emission standards will be implemented, or the implementation of the future four national and five national standards, will more test the company's technology reserves in R & D.
National III Standard Tests Domestic Technical Reserves
“At present, the models we sell on the market are all models that meet the national three emission standards.†Recently, the reporter learned from China National Heavy Duty Truck Publicity Department that China National Heavy Duty Truck has completely suspended the original emission standard model And through corresponding technological improvements, the emission standards of its commercial vehicle models will be increased to comply with the forthcoming “National Phase III Limits on Motor Vehicle Pollutant Emission Standards†(hereinafter referred to as the “National III emission standardsâ€).
