How to Write China 6 Vehicle Emission Standard?
2 Answers
China 6 vehicle emission standard is denoted as VI. The National Sixth Stage Emission Standards for Motor Vehicles refer to the standards formulated to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China, aiming to prevent and control environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. The China 6 emission standards consist of two parts: Limits and Measurement Methods for Emissions from Light-duty Vehicles, and Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles. The term 'China X' in vehicle standards refers to the National Emission Standards for Motor Vehicle Pollutants, which impose limits on the content of carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter in vehicle exhaust. The higher the number, the stricter the standard, and the relatively lower the pollution from exhaust emissions.
I remember paying special attention to the China VI emission standards when buying a car last year, as they are currently China's most stringent automotive environmental regulations. Officially called the National Sixth Stage Emission Standards for Motor Vehicles, they are implemented in two phases: China VIa and China VIb. China VIa started in 2019, followed by the full rollout of China VIb by the end of 2020. These standards impose much stricter controls on pollutants like carbon monoxide and nitrogen oxides compared to the older China V standards, applying to both fuel-powered and electric vehicles. Seeing the China VI label on the vehicle compliance certificate gave me peace of mind, as it means lower exhaust emissions, reduced air pollution, and better protection for the health of daily drivers like us. The government introduced these standards to improve environmental quality and align with global emission reduction trends. Nowadays, many new cars come standard with China VI compliance, so I recommend checking promotional materials or consulting with 4S store staff to confirm before purchasing.
