On July 1, 2013, the IV emission standards for diesel vehicles were implemented soon. However, delaying the rumors at this time is more true. Regardless of whether the rumors are rumors or facts, the industry has always been skeptical that China IV can implement it nationwide as scheduled. The implementation time of China IV has been repeatedly postponed. The reason is mainly due to product technical barriers, fuel oil and urea supply, and cost pressures arising from upgrades. Now, after a few years of preparation, product technical problems have been overcome, and additional costs are being solved by OEMs. Many companies have stated that if national IV emissions are really enforced, additional cost users have to accept it. They can only buy the national IV car that is several hundred thousand dollars more expensive than the country III. Excluding technical and cost barriers, the remaining biggest obstacle is the formulation of oil standards and the supply of urea. Industry experts have always been firm in their belief in the implementation of China IV emission standards. Jin Donghan, academician of the Chinese Academy of Engineering and director of the 711 Research Institute of China Shipbuilding Industry Corporation, insists on standardization in the attitude toward emission upgrades. He once told this newspaper that European countries have proposed standards and then tried their best to realize them. The same is true for us now. Similar to Jin Donghan, Wei Anli, deputy secretary-general of the China Internal Combustion Engine Association, believes that the National IV emission standards are in full swing. Under the pressure of the deteriorating environment, the Ministry of Industry and Information Technology, the Ministry of Environmental Protection and other departments have been stepping up the implementation of the National IV emission standards, but unfortunately China's national conditions are not the same as those in Europe and the United States. "Three barrels of oil" is not active in improving oil products. Because upgrading fuel quality requires not only technology, but also huge amounts of money. According to a rough estimate from Zhuo Chuang Information, the three major oil companies will have a conservative estimate of 50 billion to 60 billion yuan in the cost of upgrading their country's IV gasoline and diesel. Accelerated overseas expansion, infrastructure and high labor costs have forced the “three barrels of oil†financing to continue to increase and accelerate, and its liabilities have also risen sharply in recent years. How can the “three barrels of oil†built up in debt be eager to upgrade oil products? Regarding the negative attitude of “three barrels of oil†to China IV , the industry pointedly pointed out that large oil companies such as PetroChina and Sinopec, as important participants in standard setting, took the lead in violating the time of standard setting and did not explain anything. The standard officially released by the department is in an awkward position, which in fact negates the authority of national standards. The Ministry of Environmental Protection as a standard setter faces flaws. At the beginning of last year, the Ministry of Environmental Protection stated that the delay in the implementation of the standard stated that “since the current supply of automotive diesel that meets the requirements of the National IV standard is still not in place, severely restricting the implementation progress of the National IV standard to ensure the implementation of the standard, it is decided according to the actual fuel supply for vehicles. Sub-models, sub-regional implementation of national IV standards." However, Yang Zaijun, the deputy secretary-general of the National Passenger Vehicle Market Information Association, pointed out the fact that since April of this year, Nanjing has implemented national IV standards for light-duty diesel vehicles and heavy-duty gasoline vehicles, but due to the insufficient supply of national IV oil products, Local media have advised local citizens and institutions to purchase “National IV models†that can use State III diesel. When will the National IV who has been kidnapped by oil for many years be able to relax? This question may soon have answers. The State Council has come forward to order domestic oil refinery companies to upgrade and upgrade, and to ensure that qualified oil products are supplied on time according to the upgrade time of gasoline and diesel standards. Among them, PetroChina, Sinopec, and CNOOC must complete their transformation tasks as scheduled. If the hard-to-find problem of oil products can be solved, other problems will no longer be a problem. The date when the State IV oil product is in place is when the age of the State IV falls.
