What does the 'v' in vehicle emission standards represent?
2 Answers
Vehicle emission standard 'v' represents the National Phase V Motor Vehicle Pollutant Emission Standard. Places to check your vehicle's emission standard include: 1. Look behind the environmental protection compliance label sticker; 2. Check the page where the vehicle certification number begins; 3. Use the motor vehicle registration certificate to check at the local vehicle management office. Emission standards refer to the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust. Vehicle emission standards are divided into: 1. Vehicles with a total mass not exceeding 3.5 tons equipped with spark-ignition engines or compression-ignition engines; 2. Vehicles with a total mass exceeding 3.5 tons equipped with spark-ignition engines; 3. Vehicles with a total mass exceeding 3.5 tons equipped with compression-ignition engines.
When I was buying a car before, I specifically researched vehicle emission standards because government regulations are becoming increasingly stringent. The V represents the fifth-stage emission standard, such as China's National V or Europe's Euro V, mainly controlling vehicle exhaust emissions to reduce environmental harm from pollutants like nitrogen oxides and particulate matter. Upgrading to this standard means vehicles must be equipped with more efficient catalytic converters to pass annual inspections. I remember a few years ago when the country vigorously promoted National V vehicles, the prices of used cars even increased significantly. This change not only helps purify urban air but also pushes automakers to develop cleaner technologies. If you see a V symbol when buying a car, it's basically a more environmentally friendly model produced in recent years, easier to maintain, but with slightly higher replacement part costs. In short, the advancement of emission standards is particularly important for protecting our living environment.
