What is the emission standard for cars from 2008?
2 Answers
Most cars from 2008 comply with the China IV emission standard. China IV is an automotive exhaust emission standard, referring to the National Phase IV Motor Vehicle Pollutant Emission Standard. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, it controls and reduces vehicle emissions to below specified limits. Here are methods to check the emission standard of a car: 1. Check the vehicle's environmental protection label, which has clear markings on the back. 2. Take the vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 3. Check the vehicle's factory certificate.
I remember back in 2008, most cars were still at China III emission standards. That was when I just got my driver's license and bought a used Japanese sedan - the headlights still worked fine, though the exhaust was a bit black. The China III standard was implemented from mid-2007, so most 2008 models complied, but there were still some older China II vehicles on the road. Looking back now, these standards controlled exhaust emissions like carbon monoxide and nitrogen oxides much stricter than the earlier China I and II standards, making the air slightly better. Unfortunately, a decade later when China V and VI standards became even stricter, many older vehicles were either scrapped or required upgrades. As someone who's been driving for over a decade, I think understanding these standards is important - it's better not to buy overly old used cars as they might fail annual inspections or face urban driving restrictions. Times change so fast, and stronger environmental awareness is definitely a good thing.
