Diesel exhaust gas treatment fluid (commonly known as: automobile urea fluid, vehicle urea solution, and automobile environmental protection urea fluid) is a consumable product that must be used in scr technology. Used in diesel engines. It is used in scr technology to reduce nitrogen oxide pollution in diesel exhaust. Its composition is 32.5% high-purity urea and 67.5% deionized water. The scr system includes a urea tank (loaded with a diesel exhaust fluid) and a scr catalytic reaction tank. The operating process of the scr system is: when it is found that there is nitrogen oxide in the exhaust pipe, the urea tank automatically ejects the diesel exhaust gas treatment liquid, and the diesel exhaust gas treatment liquid and the nitrogen oxides undergo an oxidation-reduction reaction in the scr catalytic reaction tank, generating no Contaminated nitrogen and water vapor are exhausted. If the diesel engine exhaust fluid is not loaded, or the purity is not enough, or the quality is inferior, the vehicle engine will automatically decelerate. At the same time, the inferior quality of the diesel exhaust fluid will contaminate the catalyst in the catalytic reactor of the scr, causing serious consequences. In fact, in Europe, this policy has been implemented since 2006. European diesel exhaust fluid is called adblue. In the United States, starting in 2010, with the implementation of the epa2010 standard, the application of automotive urea fluids has also been intensified. In the United States, the diesel exhaust gas treatment fluid is called def (dieselexhaustfluid). The main representative is bluedef and so on. However, in China, the production of diesel exhaust gas is still a new industry. The def-concentration def concentration meter for pal-urea diesel engine produced by Atago Japan is specifically designed for the diesel engine industry. In Europe and the United States pal-urea has been recognized as the only reliable product for easy and accurate measurement. Diesel urea (def) can play its role only at 32.5% concentration. The use of pal-urea to maintain the appropriate concentration can ensure the effectiveness of its urea solution. The pal-urea is light and small, and the measurement method is simple. Just press the start button for 3 seconds to get the concentration. Its power supply is 2 aaa batteries and can measure about 11,000 times.

With the deepening of the concept of environmental protection, China's exhaust emission standards in recent years have reached a level of one year. China will implement mandatory iv emission standards for heavy-duty diesel engines starting in 2010. Currently, the scr (Selective Catalytic Reduction Technology) technology has become the preferred technology of the diesel engine country iv standard. Domestic engine manufacturers have begun to use scr technology to meet environmental requirements.
