What does China VI mean for passenger cars?
1 Answers
China VI for automobiles refers to vehicles that comply with the National Phase VI Motor Vehicle Pollutant Emission Standards. The China VI standard, officially known as the 'National Phase VI Motor Vehicle Pollutant Emission Standards,' includes 'Limits and Measurement Methods for Emissions from Light-duty Vehicles (China VI)' and 'Limits and Measurement Methods for Emissions from Heavy-duty Diesel Vehicles (China VI).' Here are the relevant details: 1. China VIa and China VIb: Currently, the 'China VI standard' is divided into two phases, 'China VIa' and 'China VIb,' with nationwide implementation planned for 2020 and 2023, respectively. The China VI standard, or 'National Phase VI Motor Vehicle Pollutant Emission Standards,' was established to enforce environmental protection laws, reduce and prevent vehicle exhaust pollution, protect the ecological environment, and ensure human health. 2. Differences between China VIa and China VIb: The emission standard data for China VIa and China VIb clearly show the differences between them. Compared to China VIa, China VIb imposes stricter requirements on the emissions of carbon monoxide, non-methane hydrocarbons, nitrogen oxides, and PM particulate matter, with significantly tighter limits. China VIa essentially serves as a transitional phase to China VIb.
