What does the China V emission standard mean?
2 Answers
China V standard refers to the National Fifth Stage Motor Vehicle Pollutant Emission Standard. The emission control level of the China V standard is equivalent to the Euro 5 emission standard currently implemented in Europe. The European Union has been enforcing it since 2009, imposing stricter limits on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. From China I to China IV, each upgrade in the standard reduces single-vehicle pollution by 30% to 50%. Requirements of the China V standard: Nitrogen oxides emitted per kilometer driven by a vehicle must not exceed 60 milligrams; carbon monoxide emitted per kilometer driven must not exceed 1000 milligrams; non-methane total hydrocarbons emitted per kilometer driven must not exceed 68 milligrams; nitrogen oxides emitted per kilometer driven must not exceed 60 milligrams; fine particulate matter emitted per kilometer driven must not exceed 4.5 milligrams. Reasons for implementing the China V emission standard: The goal is to reduce the total emissions of vehicle pollutants, mitigate the environmental pollution caused by vehicle exhaust, protect the ecological environment, and safeguard human health.
The China V emission standard is a major step in our country's automotive pollution control, which I've thoroughly researched while studying vehicles. Simply put, it's an emission regulation fully implemented since 2017, primarily targeting harmful exhaust gases from new vehicles, such as carbon monoxide, nitrogen oxides, and particulate matter. It's significantly stricter than the previous China IV standard, with limits reduced by about 30%, greatly reducing smog and urban air pollution. I know many car buyers pay attention to this because China V-compliant vehicles can be registered smoothly in cities and retain better value in the used car market. Personally, I prioritize eco-friendliness when driving. The China V standard requires automakers to adopt advanced technologies, such as improved catalytic converters, to make exhaust cleaner. In the long run, this benefits both health and the environment. I recommend everyone choose compliant models when buying new cars to support green transportation.
