In which year did China IV vehicles begin?
2 Answers
China IV emission standards began in 2011. Here is extended information about China IV: 1. China IV is an exhaust emission standard formulated by environmental protection departments: The larger the number after 'China', the stricter the standard, meaning the higher the number, the relatively lighter the pollution from exhaust emissions. 2. China IV emission standard is the national fourth-stage 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, the standard controls and reduces vehicle emissions to below specified levels.
I've been concerned about environmental protection for many years. The China IV emission standard was implemented in 2011, with the government introducing new regulations to reduce pollution. New vehicles had to meet the emission standards before they could be on the road. Since then, air quality has improved significantly, with fewer smoggy days, and I feel it's easier to breathe when driving. If you're buying a used car, most vehicles produced after 2011 meet the China IV standard. It's best to avoid older China I or China II vehicles, as some are restricted in certain areas. The standard has now been upgraded to China VI, but China IV vehicles are still usable. With proper maintenance, their lifespan can be extended. Remember to regularly check the emission system to avoid exceeding the standard and facing fines, while also protecting the environment.
