The plan for the sale of the National IV oil product was originally scheduled to be sold on July 1, 2011. According to the requirements of the national standard “Diesel Diesel†(GB19147-2009), this day should also be the nationwide sale of the National III diesel fuel. . However, in some areas, the supply of oil is still the State II, the State III oil is hard to see, in some cities there is even a gas station posted the State III oil standard but selling the State II oil phenomenon.
Hard to meet oil
According to the Ministry of Environmental Protection's "Replied to the Implementation Date of the Fourth Phase of the State's Motor Vehicle Emission Standards," as of January 1, 2012, diesel vehicles above 3.5 tons must meet the National IV standard; otherwise, they must not be sold or registered.
State III oil is not yet fully available. How will the National IV standard be implemented? After investigation, it was learned that the National IV vehicle diesel was available on June 30, 2012. However, it is also necessary to take into account uncertainties, that is, whether it can supply national IV vehicle diesel. In this regard, an informed source disclosed that the oil problem is only one aspect. More importantly, all aspects of the support are not ready, and rushing to start will only make the industry and companies pay a huge price.
Urea hard to supply
It is understood that at present, domestic companies have basically reached a consensus on what kind of technical route to adopt in the national IV phase: SCR (Selective Catalytic Reduction) becomes the first choice. SCR involves the issue of urea filling. At present, only the public transportation system has solved this problem. It is very difficult for trucks to find a place to add urea. In addition, this involves expenditures and it is difficult for drivers to actively add urea. The government department has the idea of ​​building a urea refueling point, but there is no concrete implementation plan.
A person familiar with the situation revealed that a complete urea supply system has not yet been completed and the construction of urea filling stations will take at least one or two years to build. Moreover, there is no clear statement as to who will pay for the money and who will be responsible for the supply. According to the survey, the number of urea stations in Guangzhou that implemented the National IV standard in advance was far below the demand, out of Guangzhou, and the urea station was almost zero. At present, standards for car urea are being formulated. The production and supply of urea is not a problem, but emphasis must be placed on quality management.
Inadequate capacity for electronic control and post-processing
When the State III standard was implemented, the situation of tight production and fixed supply of the electronic control system had made many engine plants impressive. Due to concerns about the price increase of electronic control systems, many engine manufacturers have made advance reservations and can argue that they are scrambling for electronic control systems.
Now that three years have passed, electronic control has become the mainstream route for the upgrade of emission standards. Especially in the Phase IV of the country, the electronic control system plus SCR has become the mainstream choice, and the limited capacity of the electronic control system still plagues the domestic commercial vehicle industry. Even if we add Bosch and Denso's domestic production capacity, it will only be 100,000 sets, not to mention the fact that they have to meet the needs outside China. It is estimated that in Phase IV of the country, the global demand for electronic control systems will reach 1.6 million units, while China will occupy 800,000 units. As a result, the issue of electronically controlled production capacity will be repeated.
The shortage of post-processing system capacity is also an urgent problem to be solved. Although Wuxi Kailong has recently expanded production capacity of 300,000 SCR aftertreatment systems, it is not enough to meet the needs of 2012. First, its production capacity cannot be quickly launched; Domestic companies have not fully mastered the core technologies of post-processing systems.
There is also a grim reality that the production of China IV low-sulfur oil requires specific catalysts, but no domestic ones. Many large multinational oil refineries and additive plants have invested in China for this purpose. They have established wholly-owned plants to wait for Chinese companies to buy. At that time, the entire industry will be found overseas.
The speed is not up to
An authoritative industry expert believes that from the current preparations, it is estimated that it will not be possible to implement the National IV Standard until 2016. Although there are joking ingredients, it can also be seen that the National IV standard does come too fast.
In 2011, the Ministry of Industry and Information Technology held a meeting to discuss how much time it would take to implement the National IV standard. Participants proposed that the proposal be implemented after 36 months. The companies present agreed. In addition, the China Internal Combustion Engine Industry Association submitted a proposal to postpone implementation to the Ministry of Industry and Information Technology, but the Ministry of Industry and Information Technology did not respond.
In 2011, the Ministry of Industry and Information Technology and the Ministry of Environmental Protection also publicly developed articles to solicit industry opinions. Many companies have provided feedback for this purpose, but in the end there is no report below. Until December 21, 2010, the Ministry of Environmental Protection issued a letter of reply on this matter, clarifying the timing of implementation of State IV.
Despite this, people still have doubts about whether they can implement on schedule. Judging from past experience, the implementation of new emission standards, the relevant management departments will generally notify manufacturers six months in advance, leaving sufficient time for companies to prepare. However, there has been no movement so far. It can be seen that there are different considerations between the implementation departments of the State IV.
Therefore, even if the implementation of the National IV standard began on January 1, 2012, the industry did not think it was simple. For the moment, the road to implementing the State IV is still full of thorns.
Commercial vehicle country IV implementation of difficult oil urea is difficult to supply electronic control after processing capacity is insufficient
