What is the National Vehicle Emission Standard?

[AlyssaRose]

Vehicle emission standards refer to the harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). Below is expanded information on how to check vehicle emission standards: Vehicle Conformity Certificate: When purchasing a car, it is essential to request relevant documents and certificates from the salesperson. The Vehicle Conformity Certificate clearly states the vehicle's emission standard. Although it may not explicitly label the standard as China 5 or China 6, the emission standard listed can help determine whether the vehicle meets China 5 or China 6 requirements. Environmental Information Vehicle List: The Environmental Information Vehicle List details the vehicle's environmental impact, including its tailpipe emission standard. It directly indicates the emission phase—whether it is China 5 or China 6. By reviewing this list, one can easily identify the vehicle's tailpipe emission phase. Vehicle Qualification Certificate: The vehicle's emission standard is also clearly stated on the relevant qualification certificate.
