Working Principle of Automotive Urea?
1 Answers
Working Principle of Automotive Urea: By adding urea solution as a reducing agent, most nitrogen oxides in the exhaust gas are reduced and converted into nitrogen and water, thereby ensuring that the exhaust emissions meet the standards. Additional information about automotive urea is as follows: 1. Automotive urea has strict compatibility requirements, consisting of 32.5% high-purity urea and 67.5% deionized water, with one of the quality standards being very stringent control of impurities. 2. The urea is injected into the vehicle's exhaust pipe through the urea tank injection system, where it undergoes a chemical reaction with the diesel vehicle's exhaust gas, converting the waste gas into water and nitrogen, achieving the goal of emission reduction.
