According to China's estimated holdings of diesel vehicles, vehicle urea market prospects are very broad, huge potential demand, the production technology is not complicated, rich raw materials urea. Just control the quality of the preparation of urea and water, especially the content of metal impurities can organize production, so a lot of capital into the car with the urea production process in the past. Vehicle urea prospects, can cure haze cited concern now, with the increasing demands for governance haze, PM2.5 has become the talk of hot words. It is understood that vehicle exhaust emissions accounted for about 30% of the total PM2.5 pollutants, car exhaust emissions are caused by fog and haze of the "culprit" one of the main. PM2.5 haze rule must first solve the problem of excessive solve PM2.5 exceeded should work hard in the automobile exhaust emissions. Poor supply channel is another major factor restricting car use urea market growth. Currently, car filling urea solution most convenient method is performed while refueling. However, according to insiders, in return to build a gas station car urea filling station, only two raised investment in equipment in more than 20 million, while the domestic country Ⅳ diesel ownership is still small, from investment look hard to mobilize the enthusiasm of all parties build filling stations. China Automobile Industry Association had previously called for speeding up the construction of a urea vehicle filling system, and strive to supply before the end of 2014 at a gas station along the highway and national highway vehicle urea. However, this desire has not yet become a reality. Enterprise development and environmental protection is expected to become rigid quotas, the car is still a good prospect with urea
