Vehicle specifications in the country four shopping malls in order to decrease emissions with urea, reduce pollution, protect the environment, from the beginning of 2010 to the MEP-based management department began working on the progress of commercial car exhaust emissions standards. Detailed approach is to use national IV emission norms engine to replace the country, three emission norms engines. But time and again postponed the implementation from January 1, 2011 postponed to January 1, 2012, to July 1, 2013, to the 2014's undecided moment. Although commercial State IV emission norms are not implemented in the country, but this is the trend, just moments of doubt. It is understood that the primary reason the country has repeatedly postponed the implementation of the four is in the petroleum, petrochemical exclusive unable to meet the needs of the country four diesel emissions in the country, so the car industry associations have strongly advocated a comprehensive 施行国 other oil after passing four specifications, This constitutes a sharp contrast to the strong need for early implementation of the ministry's attitude, after all the national authorities the choice of a career in stand firm. In order to ensure that the engine exhaust emissions of commercial vehicles passing, make the country four standardized, generally used in SCR skills approach, such skills need to add car AdBlue, a urea solution that is, we known, it is the NOx selective catalytic recovery agents, to 32.5 % super-purity urea and purified water. The vehicle operation, the exhaust gas out into the exhaust pipe from the turbine are mounted on a urea metering device eruptions exhaust pipe is injected into an aqueous urea solution in the urea solution and the exhaust of nitrogen oxides in the SCR reaction onset redox reaction tank to produce nitrogen and water discharge. Car exhaust nitrogen oxides is not only one of the causes of acid rain, the human body has a direct damage. The effect of the urea solution that is and car exhaust episodes chemical reaction of nitrogen oxides to form harmless nitrogen and water, and then drop the car exhaust emissions of toxic gases, reducing pollution. Currently in China producing cars with urea few companies, concerning the implementation of the country Ⅳ vital part in the huge shopping malls potential. Today, the domestic car urea production is dominated by small and medium sized private companies, ways to sell to lacking. Domestic car production by KLS, Liaoning Rady, Beijing veins chemicals, Beijing Yi Li and other companies with urea important. Each company an annual production capacity of between 10-30 million tons. During KLS, Liaoning Rady, etc. annual capacity of 300,000 tons of urea and low temperature condensation on the car has a range of questions modifier patents. KLS KLS has been the urea solution vehicle exports to Russia, Eastern Europe and South America. But on this small private companies, can not grasp the central approach is the foundation to sell the soft underbelly of its activities. We can learn from the sale of the way in Europe. First be carried out in bulk and retail sale to self pumping station. In pre-market car with urea, for the availability of Reflection on customer habits and commodities, urea Vendor primary vehicle through at a gas station, collaboration car brand of its own car repair shops, auto repair shops to establish common 210L barrels, 1000L IBC containers of used cars for sale in bulk urea solution. In 2005, bottled / IBC way of sale outlets accounted for 70% of the total sale outlets, while only 20% of the pumping station. But with the use of vehicles with a total of urea added vehicles, the proportion of the pumping station outlets gradually added to the 2011 pumping station outlets 65.1% of the total number of outlets, and the barrels / IBC proportion dropped to 29.5%. Existing European and American cars sold are often used in the production of urea suppliers - distributors alliance collaborative manner. The largest international suppliers of ammonia produced YARA mall in Europe with chemicals distributor Brenntag implemented in collaboration with urea car's brand Air1, while Mansfield is in collaboration with distributors in the United States mall. US TerraIndustries malls in the United States is through the implementation of its collaboration with Brenntag vehicle urea brand TerraCair. European cars will be sold through a network of self-built pumping stations with urea produced goods providers, such as YARA in Europe to establish its own network of Air1 pumping stations, sell directly to the car with urea. Followed by the full implementation of the country four times coming, domestic car urea annual requirement 4 million -700 million tonnes Blue Ocean mall is expected to open. The operational implementation of sophisticated shopping opportunities to capture both the company's focal point is a mall rigid requirements.
