Vehicle urea is an aqueous solution for reducing diesel vehicle exhaust, which consists of 32.5% urea and 67.5% deionized water. Kelanin is a brand of urea for vehicles.

Urea is mainly used by vehicles to reduce harmful nitrogen oxides in exhaust gas to nitrogen and water. Generally used for diesel vehicles.

The harmful substances in diesel vehicle exhaust are mainly nitrogen oxides and particulate matter. The emission of particulate matter can be reduced by technical means inside the engine, so that the exhaust gas is mainly nitrogen oxides. By injecting urea into the tail gas aftertreatment device, urea is decomposed into ammonia at high temperature, and ammonia will react with nitrogen oxides under the action of catalyst to generate harmless nitrogen and water. This device is called SCR aftertreatment system.

Pay attention to the use of urea for vehicles:

Unqualified or seriously polluted vehicle urea must be recycled to the manufacturer for centralized treatment. Can't be discharged directly;

In case of fire, a large amount of water must be used for cooling to avoid the pressure of urea tank rising sharply, and high temperature will cause urea decomposition and explosion;

In case of accidental eye contact, rinse with plenty of water for at least 15 minutes, and keep your eyes open when rinsing;

If inhaled accidentally, if the respiratory tract is stinging or uncomfortable, please move this person to a place with fresh air. If the symptoms persist, it is recommended to see a doctor and explain that the ingested product is 32.5% urea solution.

If you come into contact with clothes or skin, wash your skin with mild soap and plenty of water. If the symptoms persist, you need to see a doctor.
