In terms of environmental protection, automobile exhaust has always been a difficult trouble that must be solved. The focus of environmental protection is to deal with and solve the safety of urea, which is the basic condition for the use of diesel exhaust fluid. It can be seen from the aspects such as development of domestic environmental protection and diesel power generation that the use of diesel exhaust fluid accounts for a great proportion of automobile exhaust emission.

From the aspect of catalytic effect, diesel exhaust fluid can gradually deal with the organic matter in exhaust gas emission. Through the conversion of nitrogen, oxygen and water, the emitted materials and exhaust gas can be converted into pollution or less polluting types. This is one of the most commonly-used functions of diesel exhaust fluid. The components of diesel exhaust fluid mainly include nitrogen, oxygen and hydrogen.

Diesel exhaust fluid has not only been implemented very early in Europe, but this policy has also adopted the core standard in China, conforming to the oxidation of exhaust gas. At the same time, it allows more car owners to gradually reduce the automobile exhaust emission, reducing the cost of using diesel and gasoline. The catalytic effect of diesel exhaust fluid has always been the core of urea use.

According to the survey in recent years, in large and medium-sized cities in China, there are larger emission for trucks and buses, and the prospect of using diesel exhaust fluid is relatively promising, which also meets the market demand.
