What is the difference between China VI and China VIB?
1 Answers
China VI is more environmentally friendly than China V, with higher requirements for vehicle exhaust emissions. Both China VI and China V refer to the national automobile emission standards, officially known as "Limits and Measurement Methods for Emissions from Light-Duty Vehicles." The difference lies in the stages at which these standards were formulated. The purpose of these standards is to control and reduce vehicle emissions and improve ambient air quality. The differences between China VI and China V are as follows: 1. Different implementation times: The China VI standard was implemented in December 2014, while the China V standard was implemented in December 2017. 2. Different sulfur content limits: The China VI standard specifies a sulfur content of no more than 50mg/kg, whereas the China V standard specifies a sulfur content of no more than 10mg/kg. 3. Different particle number limits: Taking passenger cars as an example, nitrogen oxide emissions for gasoline vehicles are 25% stricter, and for diesel vehicles, they are 28% stricter. The China V standard introduced a new limit on particle numbers, with particle emission limits being 82% stricter under the China V standard. 4. Different durability mileage: The durability mileage for pollution control devices under the China V standard has doubled, increasing from the original 80,000 kilometers to 160,000 kilometers. This means that within 160,000 kilometers, vehicle emissions should meet the standard's limit requirements. 5. Different environmental protection levels: Compared to China IV, China V has higher emission standards and a higher environmental protection level.
