The implementation of the fourth national emission standard for commercial vehicles is scheduled to be implemented on July 1 this year, but the news on this aspect appears to be “quiet†on the eve of implementation and two days after implementation. The reporter registered with the Ministry of Environmental Protection, the Ministry of Industry and Information Technology, and the Automobile Industry Association official website. On the second day after the implementation of the Fourth National Standard for Commercial Vehicles, no information was found about the promulgation and implementation of any of the four national standards.
At the same time, according to media reports, the fourth national emission standard for heavy-duty diesel vehicles was once again thrown into turmoil at the last moment. The Ministry of Environmental Protection, the Ministry of Industry and Information Technology, and the Automobile Industry Association finally agreed to suspend the implementation of the four standards for commercial vehicles.
It is also said that due to the domestic oil supply can not meet the requirements, accounting for nearly half of diesel vehicles, light diesel vehicles national standards for the implementation of national standards will be postponed again, and the specific implementation time is uncertain. However, the national standard for heavy-duty diesel vehicles will be implemented as of July 1. The above statement and the former director of the Ministry of Environmental Protection's Motor Vehicle Sewage Disposal Monitoring Center Tang Tong also agreed with the media: the heavy firewood will not be postponed and the light firewood will be postponed.
In May and June of this year, the Ministry of Environmental Protection repeatedly emphasized that the heavy-duty vehicle emissions could not be postponed. At the same time, the Automobile Industry Association and the Ministry of Industry and Information Technology also expressed their attitude: Vehicle oil should be synchronized. The Automobile Industry Association even appealed to the National III heavy-duty diesel engines and models already existing in the “Announcement†to recommend a further six-month sales transition period after the “National Three-vehicle diesel and automotive urea solutions were in place throughout the country. After the transition period expires, production, sales and registration are stopped."
Until July 1 of this year, 350ppm (National Standard) diesel began to supply to the whole country. When the national standard diesel supply is still available in the country indefinitely, the technology used in the National IV light diesel vehicle is only applicable to the sulfur content of 50ppm. (4) Standard diesel oil, the current oil product cannot meet the requirements of the new standard diesel engine and exhaust gas aftertreatment device.
Prior to this, Dong Yang, executive vice president and secretary general of the China Association of Automobile Manufacturers, also stated that: To upgrade to the national standard, the denitrification agent is completely untouched. Although the company says that it can produce, the distance from the realization of the production process to the use is too long to be implemented. Measures. If after the implementation of the national four diesel, denitrification agent supply shortage, how to do damage to the car, consumers tell us how to do, law enforcement agencies on the way to deduct the car how to do?
“We are also trying to figure out how to implement the policy. Once the national standard is implemented, SCR (selective catalytic reduction) will be added behind the vehicles using common-rail technology. Now common rail technology and SCR are mostly held by foreign manufacturers. Common rail and SCR, how to increase the cost of production brought about by the upgrading of technology will be a big problem. In addition, the installation of SCR requires the addition of urea to gas stations, and there are no urea supply points in China's current highway gas stations.†A heavy truck company technical director said.
At present, there are reports that local governments in 18 regions have already announced that they will implement State 4 (including registration and transfer) on schedule on July 1. However, due to the uncertainty of the central policy, dealers all over the country have indicated that they have not begun to reserve four models of the country, and customers can still purchase the three cars at each 4S shop and can be listed. The huge uncertainty of emission standards, engine companies, automakers, distributors and users are increasingly watching, and before that, the major manufacturers and suppliers' technical upgrading and active preparation may be shelved again.
