How many more years can a National 4 car be driven?
2 Answers
As long as the car is in good condition, a National 4 vehicle can continue to be driven, but some cities may impose driving restrictions on National 4 cars. Here is extended information about the National 4 emission standards: 1. The National 4 emission standard was implemented starting in 2011 until the National 5 standard was introduced in 2018. Vehicles produced between 2011 and 2017 generally comply with the National 4 standard. The National 4 standard requires emissions of various pollutants to be approximately 50% lower than those under the National 3 standard. 2. The National 4 emission standard is the fourth stage of China's motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). 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 aims to control and reduce vehicle emissions to levels below specified limits.
I drive a China IV emission standard vehicle, which I've owned for about seven or eight years now, and I feel it can still be used for some time. The key factor is the policies in your city; major cities like Beijing and Shanghai have already implemented traffic restrictions, limiting China IV vehicles in certain areas, but smaller cities or rural areas basically have no restrictions. As long as the vehicle passes the annual inspection and meets emission standards, it can continue to be driven. My personal approach is to regularly visit the repair shop to clean the exhaust pipe and the three-way catalytic converter, which helps reduce pollution levels to pass inspections. The government hasn't mentioned a complete ban in recent years, but in the next five years, they might introduce scrapping subsidies to encourage switching to electric vehicles. From an economic perspective, changing cars isn't cheap, so I plan to keep driving mine for now while staying updated on local environmental notices. As long as maintenance costs aren't high, I think it can still run for another six or seven years without issues. Overall, proper maintenance plus keeping an eye on policy changes is sufficient; there's no need to worry too much.
