Vehicle urea protects the country's four emission standards

In the voice of many doubts and arguments, 18 cities such as Nanjing, Qingdao and Chengdu have announced the implementation of the national standard as scheduled. Although it will take some time for the National IV policy to be fully implemented nationwide, the pacesetter has already taken the most difficult step. As long as everyone has enough courage and perseverance, it will certainly be able to cross the four-nation roadblock. The password for "implementation of State IV" has already been issued. What problems are involved in the specific implementation? Due to the influence of national conditions, oil products and other factors, the main line used in the upgrading of China's National IV is SCR. In the SCR technology route, adding vehicle urea is the key to meeting the national IV emission standards. As a result, the status quo of domestic vehicle urea will determine the specific effect of the implementation and implementation of the National IV.

Car urea promotes difficult and flexible filling

This is a rather special moment in the commercial vehicle industry. As you can see, the trucks of the country’s third national and second-largest trucks loaded with goods have successively passed through an intersection marked with traffic lights. It is said that traffic lights will turn red, and all commercial vehicles that fail to meet the national standards will not be able to pass. Manufacturers, supporting companies, oil companies and related product manufacturers are all staring at this traffic light, hoping to take action in the first time of change, layout the market. The “Rookie” car urea in the market, which is closely linked with the National IV, has attracted many attention.

Then, is the essential vehicle urea solution for the National IV diesel vehicle convenient for drivers to add at any time? In the implementation of the National IV problem, the imperfect vehicle urea filling equipment has been listed as one of the four “hurdles” in the industry. Domestic vehicle urea solution is not yet a complete supply system, to meet the timely addition of urea solution is still a major problem everywhere, the establishment of a complete urea solution supply system to ensure the normal supply of urea solution to the problem to be solved.

In the central media “National IV's implementation of industrial readiness”, it was learned that at present, Meifengjia Blue's automotive urea solution products are available in 10L, 20L small packages and 1TIBC tons of drums. For the promotion of the product, Wu Jiangtao, general manager of Sichuan Meifengjialan, said that the current promotion of domestic vehicle urea is mainly based on small packages, and some companies will use 1TIBC tons of barrels for use with filling pumps. China does not have the conditions for construction of refueling stations in the early stage. According to the mature vehicle urea promotion model in Europe, it is expected that domestic refueling stations will not appear on a large scale in at least 3-5 years. "From the general introduction of Wu can understand, small packaging promotion for the current domestic vehicle urea promotion form, to meet the needs of the four diesel vehicles.

Product temperature requirements are strict with thermal storage devices

Car urea is more stringent in temperature requirements and crystallizes below -11°C. This problem has aroused the attention of the majority of truck drivers. Truck drivers run around the country all year round. The extremely cold areas in the north may cause the urea to crystallize. This phenomenon is troublesome to the trucker's transportation schedule. Wu explained: “The urea solution for small-packed vehicles can be stored indoors to avoid low-temperature crystallization. In an SCR system for automotive assembly, the storage tank for storing urea solutions for vehicles has a thermal insulation function, and the system is equipped with a heating device. It can prevent the product from crystallizing under low temperature environment and ensure the normal operation of the system."
