The use of urea solution is seemingly simple, in fact there are many places to pay attention to.
Correct understanding and use of the car urea solution: The most basic function of the urea solution is to convert the NOx into harmless nitrogen and water, save energy and environmental protection to meet the national emission standards stipulated by the car. Through the intelligent control of the SCR system, when the urea solution in the storage tank is insufficient, the car will not start up, in order to ensure the normal driving of the vehicle, should be equipped with adequate urea solution. The most basic function of this car urea solution is to convert the nitrogen oxides in automobile exhaust into harmless nitrogen and water, energy saving and environmental protection to meet the national emission standards stipulated by the car.
Through the intelligent control of the SCR system, when the urea solution in the storage tank is insufficient, the car will not start up, in order to ensure the normal driving of the vehicle, should be equipped with adequate urea solution. In addition, the use of different quality of urea solution, the maintenance of vehicles is also different. When the choice of urea solution is not pure enough, particulate matter, heavy metal ions and other impurities exist, the vehicle SCR system of the nozzle, filters and other components caused serious damage, resulting in unnecessary economic losses.
Low-quality urea solution if the chemical composition is not high, the presence of heavy metals and other chemical components, will be chemical reaction with the catalyst to reduce the effect of tail gas conversion, and even lose effect. Therefore, in the selection of urea solution should be as far as possible to choose high-quality products to control the vehicle maintenance costs.
