What does China National V and VI mean for vehicles?
2 Answers
China National V and VI represent the emission standards for vehicle exhaust. Below is an introduction to National V and VI: 1. National V refers to the fifth stage of motor vehicle pollutant emission standards, with its emission control level equivalent to the Euro 5 emission standard currently implemented in Europe. 2. National VI refers to the sixth stage of motor vehicle pollutant emission standards. Below is additional information about National V and VI: 1. After a vehicle starts, the tailpipe emits harmful gases such as carbon monoxide, soot, and PM. Changing the vehicle's emission standards is aimed at effectively reducing the pollution of these wastes to the atmosphere. 2. The National VI standard is stricter than National V. 3. Registered National V emission vehicles must meet local emission standards and pass vehicle inspection before they can be driven.
Previously, I focused on environmental protection and learned that China 5 and China 6 are vehicle emission standards related to air cleanliness. Simply put, China 5 is the National Phase 5 standard, implemented in the mid-2000s, which limits exhaust pollutants; China 6 is the Phase 6 standard, mandatory since 2019, with stricter limits on pollutants like carbon monoxide and nitrogen oxides. This has a significant impact on our daily lives, especially in big cities, where increased driving during poor air quality can be harmful. After my hometown city implemented these standards, the smog decreased noticeably, and the air quality improved. China 6 vehicles are designed with more advanced features, such as additional filters. Although they may be slightly more expensive to purchase, they are more fuel-efficient and save on long-term maintenance costs. Overall, upgrading emission standards is a national effort to protect the environment. As a resident, I support choosing China 6-compliant new vehicles to contribute to the health of future generations.
