How to Distinguish Between National IV and National V Vehicles?

[ValentinaLee]

For vehicles that have already received the environmental inspection compliance label, the emission standard can be viewed on the original or duplicate of the environmental inspection compliance label; alternatively, you can log in to the Motor Vehicle Environmental Protection Website and enter the vehicle model and engine model in the new vehicle compliance query system to find out. Below is extended information about National V and National VI standards: 1. National IV and National V are emission standards for exhaust gases. The National V standard is equivalent to the Euro V standard in the European Union, which has been implemented since 2009. It imposes stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emitted by motor vehicles. 2. From National I to National IV, each upgrade in the standard reduces vehicle pollution by 30% to 50%. The fifth phase of the national motor vehicle emission standard was implemented nationwide starting from January 1, 2018.
