Where to Add Automotive Urea in a Vehicle?

[ValerieFitz]

Automotive urea is added into a dedicated urea storage tank, which is located near the fuel tank. The primary reason for adding urea in diesel vehicles is to reduce exhaust emissions. The nitrogen oxides emitted can be catalytically reduced by the ammonia produced from the high-temperature hydrolysis of urea into harmless nitrogen and water, which are then released into the atmosphere. Relevant information about automotive urea is as follows: 1. Automotive urea is an essential additive for the SCR (Selective Catalytic Reduction Technology) solution. 2. The SCR system includes a urea tank (containing diesel exhaust fluid) and an SCR catalytic reaction tank. 3. The operation process of the SCR system is as follows: when nitrogen oxides are detected in the exhaust pipe, the urea tank automatically sprays diesel exhaust fluid. The diesel exhaust fluid and nitrogen oxides undergo a redox reaction in the SCR catalytic reaction tank, producing non-polluting nitrogen and water vapor, which are then released.
