Recently, the Ministry of Environmental Protection issued the “Announcement on the Implementation of the National Phase IV Heavy-duty Vehicle Gasoline Engine and Vehicle Emission Standards†(hereinafter referred to as the “Announcementâ€). It is clear that from July 1st next year, heavy-duty vehicle gasoline engines and The car must meet the requirements of the national IV standard. The "Announcement" stated that since July 1, 2013, all production, import, sales, and registration of heavy-duty vehicle gasoline engines and vehicles must comply with the requirements of the National IV standard, and related companies should promptly adjust production, import, and sales plans. . Since the start of 2010, the implementation of the National IV Standard has been delayed several times. Prior to this, for the date of implementation of the July 1, 2013 date set by the Ministry of Environmental Protection, many people in the industry were skeptical. Now, the Ministry of Environmental Protection has repeatedly issued a document stating that it is in commercial use. The determination of the car to implement the national IV standard. However, from the perspective of market feedback, the National IV standard has to be implemented and implemented throughout the country. It is still a difficult task and it needs to cross several barriers. First hurdle: oil products According to industry experts and business people, oil products are already recognized as one of the issues, but this does not depend on the entire vehicle company. Enterprises hope that before the implementation date comes, there will be a breakthrough in oil supply. “Now, the relevant domestic supporting facilities are not formed. Taking urea as an example, the relevant supporting measures for the production of urea and even urea are still not perfect, and the relevant industries should keep up with the progress in order to better and faster promote the national IV standards. What is difficult is that China IV oil cannot be fully supplied,†said Wei Libao, chief engineer of the technical department of FAW Jiefang Automobile Co., Ltd. Second Road: Technology Regarding the technical route, each vehicle company has its own emphasis. For example, heavy vehicles are mainly based on SCR technology. However, this technology route is highly dependent on urea. The vehicle manufacturer recommends that the State strengthen the management and supervision of urea production enterprises, including related auxiliary facilities. In the light vehicle technology line, various vehicle companies have different opinions. Some enterprises recognize DOC or DOC+POC technology routes, while others believe that technical routes such as DPF+DOC or DOC+POC can be implemented, but the advantages and disadvantages are not. one. The country IV technology has matured. There is no doubt about this, but there are too many hardships behind it. "If post-processing technologies and electronic control technologies are all in the hands of foreign companies, it is not impossible for them to be realized at home, but it is difficult at this stage." Wei Libao told reporters, "The current key spare parts technology is mostly in the hands of foreign companies, and many parts and components are purchased. All are foreign products, mainly in Corning, Bosch, etc." In this regard, Bei Wei, deputy chief of the electronic control calibration division of Beiqi Foton Motor Co., Ltd. also gave his opinions. He said: “For the implementation of the relevant regulations of the National IV standard by the Ministry of Environmental Protection, companies have done related work seriously and the products have been It is necessary to mention that, at present, key technologies are mostly controlled by foreign companies, but the level of domestic manufacturing processes is relatively low, and the capacity of supporting enterprises is slightly insufficient, and it must be strengthened in product consistency and other aspects." The third hurdle: the market How to let end users accept? To this problem, Yang Xiyuan, chief of the engine department of Dongfeng Motor Co., Ltd. Commercial Vehicle Technology Center, believes: “For ordinary people, commercial vehicles are production materials, as long as they can transport goods from one place to another, and at the same time pay a price. As small as possible, users will be satisfied, but the purchase of national IV vehicles is likely to bring a cost burden to users.Therefore, we can only improve the quality, reduce the user's use, maintenance costs, improve its transport efficiency. In addition, reducing vehicle fuel consumption is also one of the measures. According to the internal test sample data, the use of SCR technology in the National IV vehicle can indeed improve fuel economy. †Relevant person in charge of a vehicle company stated that the state implements the national IV standard, and the corresponding national IV product and supporting component system will eventually fall on the issue of localization, so that the company can fundamentally reduce the cost pressure, otherwise the pressure will be passed on to In the terminal market, users are hard to accept. Market potential forecast If the above problems can all be solved properly, then what impact will the implementation of the National IV standard bring to the domestic heavy truck market? According to relevant departments' forecast, the new market brought by China IV will exceed 10 billion yuan. What is the stage for China IV to be held in the second half of next year? Some financial institutions predict this, in the short term, due to the obvious cost advantage of heavy-cargo-III products, in the first half of 2013 before the mandatory implementation of the national IV standard, the Chinese-type III heavy-duty trucks may gain high market enthusiasm. In the case that the annual sales volume of the heavy-duty truck market does not increase or even shrink, the space reserved for China IV in the second half of next year may be relatively small, and in 2014 it is expected to fully explode.
