The logo for the National V standard is the letter 'v'. Below is a partial introduction to the National V standard: 1. Standard Overview: The National V standard is equivalent to the EU's Euro 5 standard, which has been implemented in the EU since 2009. It imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Each upgrade from National I to National IV reduces single-vehicle pollution by 30% to 50%. As of January 2013, the National V standard was still in the solicitation phase. 2. Implementation Time: The National V standard was implemented nationwide on January 1, 2017, as the fifth stage of the national vehicle emission standards. Cities like Beijing, Shanghai, Nanjing, and parts of Guangdong have already begun enforcing the National V standard. Starting April 1, 2016, all imported, sold, and registered light-duty gasoline vehicles, light-duty diesel passenger vehicles, and heavy-duty diesel vehicles in the Beijing-Tianjin-Hebei region must comply with the National V emission standard.
