Vehicle urea solution most basic function is to automobile exhaust of nitrogen oxides into harmless nitrogen and water, energy saving and environmental protection to make your car emissions to achieve the national standard. Through the intelligent control of the SCR system, when the shortage of urea solution storage tank, the car will not start up, in order to ensure the normal running of the vehicle, shall be provided with sufficient urea solution. In addition the choice of different quality urea solution, for maintenance of vehicles are different. Resulting urea solution elected by the purity is not enough, there is particulate matter, heavy metals and other impurities when the vehicle SCR system will nozzles, filters and other parts of serious damage, unnecessary economic losses. Low quality urea solution is not high if the chemical composition, the presence of heavy metals and other chemical components, will react with the catalyst to reduce exhaust gas conversion effect, even useless. Therefore, when the urea solution in the selection should try to use high-quality products, in order to control the maintenance cost of the vehicle. Our country Ⅳ diesel vehicle emission standards have been performed nearly six months, according to the survey, Shandong, China Network reporter, as to make catalytic reducing exhaust emissions standards - Vehicle urea solution, as part of the regulatory standards in place, poor supply channels, Market demand is not expected to usher in the explosive growth, while car production capacity of urea has jumped, the entire industry into a quagmire of overcapacity. 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. January 2015, diesel emissions standards increased from country to country Ⅲ Ⅳ, exhaust emissions standards generally require the use of selective catalytic reduction (SCR) technology, the use of car exhaust with urea solution to deal with nitrogen oxides, nitrogen oxide It was converted into harmless nitrogen and water. State Ⅳ diesel vehicles in use, the amount of urea 3% to 5% of the fuel consumption of each country Ⅳ standard vehicles Truck annual consumption of about two tons of urea. 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.
