How to Check the Emission Standard of a Motor Vehicle?

[VanOlive]

Here are the methods to check the emission standard of a motor vehicle: 1. The simplest and most direct way is to look at the vehicle's environmental protection label, which has a clear mark on the back. 2. Log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring the motor vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 4. Differentiate based on the year the vehicle was registered. Vehicles registered after 2008 are National IV; those registered in 2007 are National III. Below is additional information on motor vehicle emission standards: 1. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). 2. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, vehicle emissions can be controlled and reduced to below the specified standards.
