Is Automotive Urea Solution necessary?
Automotive Urea Solution used for the treatment of nitrogen oxides emitted by vehicles, first of all, we need to look at the regulations on nitrogen oxides in various regions:
The EU introduced Euro IV in 2005: standard 3.5 g/kWh; Euro V in 2008: standard 2.0 g/kWh; Euro VI in 2013: standard 0.25 g/kWh. China implemented National III standard on July 1, 2008, National IV standard on January 1, 2015, National V standard on January 1, 2017, National 6A standard on July 1, 2020, and National 6B standard on July 1, 2023.
In summary, diesel vehicles must be treated with Automotive Urea Solution for nitrogen oxide management.
What happens if I forget to add Urea Solution?
If the Automotive Urea Solution is not added in a timely manner, the OBD system in the car will display a fault light, the engine torque output will decrease, and NOx will not meet the emission standards, which will also result in punishment from the environmental protection department.
