Automotive urea is a liquid used in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. It is applied in diesel engines. Diesel Exhaust Fluid (commonly known as automotive urea, vehicle urea, or automotive environmental urea in China) is a consumable essential for SCR technology. Here is more information about automotive urea: 1. Automotive urea can catalyze the reduction of nitrogen oxides (NOx) in diesel vehicle exhaust into harmless nitrogen (N2) and water in the Selective Catalytic Reduction (SCR) system. 2. If urea is not used, or if the urea quality is inferior or purity insufficient, it can cause the vehicle's engine to automatically reduce speed and pollute the catalyst in the SCR catalytic reaction tank, leading to serious consequences. 3. Generally, the remaining amount of urea is displayed on the dashboard (similar to the fuel gauge). When the urea is depleted, a vehicle indicator light will illuminate as a reminder. The usage of urea is approximately 3% to 5% of the fuel consumption.
