What is Automotive Urea?

Automotive urea is a colorless, transparent liquid stored in the urea tank. When sensors detect nitrogen oxides in the exhaust pipe, it automatically sprays atomized automotive urea, which mixes with the nitrogen oxides and undergoes a redox reaction in the SCR catalytic reaction tank, ultimately producing non-polluting nitrogen and water that are expelled. Automotive urea is an essential additive for the SCR (Selective Catalytic Reduction) solution. The SCR system includes a urea tank (containing diesel exhaust fluid) and an SCR catalytic reaction tank. The primary harmful substances in diesel vehicle exhaust are nitrogen oxides and particulate matter. While particulate emissions can be reduced through technical means within the engine, nitrogen oxides remain the main component of the exhaust. By injecting urea into the exhaust after-treatment device, the urea decomposes into ammonia at high temperatures. Under the action of a catalyst, the ammonia reacts with nitrogen oxides to produce harmless nitrogen and water. This device is called the SCR after-treatment system.

What is the function of a bumper?

The function of a bumper is to absorb and mitigate external impact forces, protecting the front and rear parts of the vehicle body, serving as a safety device. Bumpers have the capability to reduce injuries to occupants during high-speed collisions and are increasingly designed for pedestrian protection. In addition to maintaining their original protective functions, the front and rear bumpers of cars also aim for harmony and unity with the vehicle's styling and pursue lightweight design. The front and rear bumpers of cars are made of plastic, commonly referred to as plastic bumpers. Typically, a car's plastic bumper consists of three parts: the outer panel, cushioning material, and crossbeam. The outer panel and cushioning material are made of plastic, while the crossbeam is formed by stamping cold-rolled steel sheets into a U-shaped channel; the outer panel and cushioning material are attached to the crossbeam.
