How to Determine the Emission Standard (National IV/V/VI) from the Vehicle License

[DeNevaeh]

Here are the methods to check a vehicle's emission standard (National IV/V/VI) from the vehicle license: 1. The vehicle model number can be found on the vehicle license. 2. In the vehicle model number, 'Y' represents the National V emission standard, while 'V' represents the National VI emission standard. Below are the differences between National V and National VI emission standards: 1. The main difference between vehicles meeting National V and National VI standards lies in the use of high-performance three-way catalytic converters in National VI vehicles. 2. Compared to National V vehicles, National VI vehicles emit fewer pollutants, thereby reducing atmospheric pollution to some extent. 3. After the implementation of the National VI standard, vehicle emissions will be reduced by over 50% compared to the National V standard, with carbon monoxide, hydrocarbons, and non-methane hydrocarbons decreasing by 50%, and nitrogen oxides decreasing by 42%.
