What is the National V Emission Standard Symbol?
3 Answers
National V Emission Standard symbol: National V. Detailed introduction is as follows: 1. National V standard: 'Limits and Measurement Methods for Emissions from Light-duty Vehicles' was issued by the Ministry of Environmental Protection on September 17, 2013. Starting from January 1, 2018, all motor vehicles nationwide will fully implement the National V emission standard. 2. Differences between National V and National IV: Compared with National IV, the new standard reduces nitrogen oxide emissions from light-duty vehicles by 25% and from heavy-duty vehicles by 43%. Starting from July 1, 2017, all heavy-duty diesel vehicles manufactured, imported, sold, and registered nationwide must comply with the National V standard requirements.
The China 5 emission standard itself does not have a specific visual identifier like an icon or logo. As a car owner, I remember that to confirm whether a vehicle meets the China 5 emission standard, the main method is to check the vehicle identification number (VIN), especially the 10th character of the VIN, which represents the production year. For example, vehicles produced in 2013 and later generally meet the China 5 standard, with specific letters like M or N depending on the manufacturer's settings. This is quite important because China 5 vehicles have stricter emissions than China 4, reducing PM2.5 and nitrogen oxide pollution, and in some major cities, only China 5 vehicles are allowed to enter the city center under traffic restriction policies. When buying a car, I check the vehicle conformity certificate or environmental protection list, which clearly states the emission standard level. Extra caution is needed in used car transactions—scanning the VIN with a mobile app can reveal whether the car meets the standard, avoiding the purchase of non-compliant vehicles. Overall, China 5 is a step forward in environmental protection, but the future China 6 standard will be even stricter. Understanding these can help you save money when buying a car while supporting environmental protection.
China's National V emission standard does not have a specially designed unified logo symbol. From a consumer perspective, I've experienced this firsthand—it mainly relies on decoding the VIN code. The 10th letter of the VIN corresponds to the production year; for example, a 2014 vehicle might use the letter P to indicate National V standard. Before purchasing a car, I usually check VIVIN websites or apps by entering the VIN for clear information. This directly affects practical costs, as National V vehicles enjoy benefits like no driving restrictions in certain cities and higher used-car values. Additionally, the National V standard requires technological upgrades, such as improved three-way catalytic converters to reduce exhaust emissions. Although it's harder to visually determine without the environmental sticker, mastering the VIN query method is simple and practical—it’s both convenient and helps avoid policy risks.
