Where to Add Automotive Urea?

[SanKingston]

Automotive urea is added into the urea tank, which is located near the fuel tank. The formal name of automotive urea is Diesel Exhaust Fluid (DEF). Diesel engines generally have a dedicated device, similar to a box, commonly known as the urea tank, which contains the automotive urea solution. When the vehicle is in motion, it continuously emits nitrogen oxides (NOx), and the urea is also constantly being consumed, so the urea needs to be replenished periodically. Automotive urea is specifically for diesel engines because diesel engines emit nitrogen oxides during operation, which are harmful to both the atmosphere and human health. Long-term exposure to these gases can cause respiratory diseases. To reduce the pollution of these gases to the atmosphere and the environment, urea is used. The urea solution reacts with NOx through a reduction process, producing nitrogen, oxygen, and water, thereby reducing the emission of nitrogen oxides.
