Which years do National IV vehicles belong to?
2 Answers
The National IV emission standard began in 2010 and lasted until 2018 when the National V standard was implemented. Therefore, vehicles produced between 2010 and 2017 generally comply with the National IV standard. Here is more information about the National IV standard: 1. The National IV standard requires emissions of various pollutants to be approximately 50% lower than those of the National III standard. 2. The National Fourth Stage Motor Vehicle Pollutant Emission Standard, abbreviated as "National IV Emission Standard" or National IV Standard, primarily targets vehicle emission pollutants such as HC, NOx, CO, and PM. Through the application of technologies like the active layer of catalytic converters, secondary air injection, and exhaust gas recirculation systems with cooling devices, it controls and reduces vehicle emission pollutants to levels below specified limits.
I'm a car enthusiast who deals with automotive environmental standards all day. China IV represents the fourth phase of China's emission standards, which was uniformly implemented nationwide for new vehicle production starting from July 2011. Major cities like Beijing, Shanghai, and Guangzhou actually piloted it as early as 2008. So, to answer your question about which year's vehicles, simply put, models produced between 2010 and 2017 are most likely to be China IV compliant. Of course, you'll need to check the vehicle's nameplate or VIN for specifics, as some transition-period vehicles might be slightly later. This standard was promoted to reduce harmful exhaust emissions and improve air quality. Don't just look at the production year - also pay attention to regional policies, as some areas restrict pre-China III vehicles, making China IV models particularly sought-after. If you're shopping for used cars, try to choose 2013 models or newer for better reliability. I believe environmental regulations will only get stricter, making future China VI vehicles more worth watching.
