Recently, the relevant state agencies announced that on July 1 this year, a single gas vehicle, light-duty gasoline vehicle, and dual-use fuel vehicle will formally implement the National 4 emission standards. Judging from the limits of environmental protection standards, the National IV standard requires that on the basis of State III, the emission of pollutants from light-duty vehicles should be reduced by about 50%, the emissions from heavy-duty vehicles should be reduced by about 30%, and the particulate emissions should be reduced by more than 80%.
Under normal circumstances, every technological innovation in the automotive industry will cause great repercussions, and the impact will also be very close. However, due to the implementation of the motor vehicle country 4 standard in the previous major events such as the Beijing Olympics and the Shanghai World Expo, the national 4 standard is Since the plan was fully implemented and lasted for three years, both the top and bottom of the market have been stable.
In the face of the transformation of commercial vehicles from State III to State IV, the technical difficulty is not great, and the structure of the engine does not need to be changed much. It is only necessary to upgrade the fuel injection control and exhaust gas purification.
Some manufacturers are also very calm about this, "The company's technology upgrade and transformation certainly have a certain cost, but this was completed a few months ago, and all the current sales to the market are the National IV models." SAIC-GM-Wuling Sales Company Yang Jie, general manager, said: "Continuing to produce a model III may sell more cars, but it will affect future sales." Dongfeng Fengshen public relations department, said with the cattle, said, "The previous production and transformation have been completed, the country is currently selling models All of them are National IV models.†Great Wall Motor’s propaganda minister Shang Yugui also stated in his personal microblog that “Great Wall’s cars that have been listed since 2009 are all State IV, and diesel Haval also has State IV, and the sales of major models are not affected. Diesel III is not subject to regulations and will not be affected."
In the dealers put face, it is to seize the existing inventory. Due to the fact that in China, with the exception of first-tier cities and individual capital cities, most of the second- and third-tier cities’ light-duty vehicles use the National III standard. If a consumer purchases a new vehicle that does not meet the national IV emission standard, he will not be able to apply for a license for the motor vehicle after July 1. Therefore, manufacturers have already reminded distributors to digest the inventory of China III models, and dealers have begun to gradually clear the market. The prices of the national III models on the market are far lower than the national IV models. "This year, the auto market is not hot enough, so there are still a number of national III models in the hands. Now we are stepping up sales promotion." A dealer in Zhengzhou, Henan Province, said, "If we can't digest it completely, we can continue to digest it through branded sales."
However, the quality of oil products has become a major obstacle to China's implementation of the National IV standard. As early as the end of last year, the Ministry of Environmental Protection had sent a copy of the National Motor Vehicle Emission Standard Phase IV limit to the China Association of Automobile Manufacturers. Implementation date reply. According to the document, “As the National IV vehicle fuel oil standard has not yet been introduced, it is still unable to ensure that the corresponding vehicle fuel oil is supplied nationwide, which will bring certain difficulties for the full implementation of the motor vehicle IV standard. The Ministry of Environmental Protection of the motor vehicle is the national IV standard. Implementation date is adjusted.
According to experts, “The use of State III gasoline in the China IV model will not cause any significant impact on the vehicle itself in most cases, but the emission standards may not meet the established requirements.†At the same time, “For commercial vehicles using diesel engines, The IV standard will be even more difficult to upgrade the technology.†Because of diesel engines, whether it is a light-duty diesel engine or an economical fuel injection system, the core technology is still being mastered by some multinational companies.
It is not difficult to convert technology from the country itself to country three to country four alone. Most companies have already completed or are implementing technological reforms. The fuel problem is an important factor affecting the upgrading of China's environmental protection standards, due to the lack of key components and core technologies. It is a bottleneck affecting the upgrading of China's auto technology.
