What is the difference between China IV and China V vehicle emission standards?
2 Answers
The differences between China IV and China V vehicle emission standards are: 1. Different emission standards: China IV is the national fourth-stage motor vehicle pollutant emission standard; China V is the national fifth-stage motor vehicle pollutant emission standard. 2. Different emission pollutants: The main pollutants emitted by China IV vehicles are hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter; The main pollutants emitted by China V vehicles are nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. Methods to determine whether a vehicle meets China IV or China V standards: 1. Check the original and duplicate copies of the environmental inspection compliance label; 2. Log in to the Motor Vehicle Environmental Protection Website and enter the vehicle model and engine model in the new vehicle compliance query system to check.
As a seasoned driver with years of experience, let me talk about the differences between China IV and China V vehicle emission standards. The main change lies in the stricter emission criteria. China V imposes more stringent limits on pollutants, such as significantly reducing nitrogen oxide and particulate matter emissions, which is crucial for improving urban air quality. I remember China IV vehicles were still passable for city driving a few years ago, but after China V was implemented, there was a noticeable reduction in smoggy days, and we see blue skies more often while driving in cities. Additionally, China V requires vehicles to be equipped with better fuel systems that emit less exhaust, resulting in stronger environmental benefits. In the long run, this is beneficial for everyone as it reduces the risk of respiratory issues. However, the upgrade process isn't simple—automakers had to change engine technologies and enhance catalytic converter filtration functions, which promoted greening across the entire industry. I suggest that new car buyers pay more attention to emission standards and opt for China V or higher standards for better health. After all, the global trend is moving toward environmental protection, and China is already pushing for China VI standards.
