What is the China VI Standard?
2 Answers
China VI Standard is: 1. Carbon monoxide emission content is 700mg. 2. Non-methane hydrocarbon emission content is 68mg. 3. Nitrogen oxide emission content is 60mg. 4. Particulate matter emission content is 4.5mg. 5. China VI refers to the National Sixth Stage Emission Standard for Motor Vehicle Pollutants, which includes the emission limits and measurement methods for light-duty vehicle pollutants and the emission limits and measurement methods for heavy-duty diesel vehicle pollutants. The objectives of implementing China VI are as follows: 1. To prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles. 2. To protect the ecological environment and safeguard human health.
The China VI standard is the latest automotive emission regulation implemented in China, gradually rolled out since 2019 with the aim of making new vehicles less polluting and more environmentally friendly. I pay special attention to these changes when driving, as they directly impact our city's air quality. Specifically, China VI imposes stricter limits on harmful substances in exhaust emissions, such as carbon monoxide and nitrogen oxides, compared to the China V standard. Automakers must equip advanced devices like particulate filters to meet the requirements. This is no small matter—it affects us car owners too. For example, when buying a new car, choosing one with China VI certification helps reduce our personal carbon footprint and contributes to cleaner air in the long run. However, implementation comes with challenges, such as phasing out older vehicle models. Still, I believe environmental protection is an inevitable trend, and we should actively support it.
