Vehicle urea solution, that is, diesel engine exhaust treatment liquid, is a colorless, transparent and clear liquid, which was first used in Europe. It is packed in a urea box. When nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays urea for vehicles, and the two react in the SCR reaction box to generate pollution-free nitrogen and water discharge.

Principle of urea solution for vehicles;

1. When the temperature is 70-75℃, urea is hydrolyzed in aqueous solution.

2. When the temperature is lower than 30℃, urea will crystallize out of the aqueous solution again.

3. The purity of urea will be greatly improved after each hydrolysis and crystallization. Ordinary industrial grade urea can meet the standard requirements of vehicle urea after one-time hydrolysis and crystallization, and its output ratio is 1.5: 1.

Components of vehicle urea solution:

The vehicle urea solution is a solution made of high-purity urea and pure water, without any other additives, and the urea content in the solution is 32.5% (mass fraction). Million car purchase subsidy
