What are the differences between National Standard V and VI for vehicles?
2 Answers
The differences between National Standard V and VI for vehicles are as follows: 1. Different sulfur content: The sulfur content limit for National Standard VI gasoline is 50mg/kg, while for National Standard V gasoline, it is 10mg/kg. 2. Different implementation times: The National Standard VI was implemented in December 2014, whereas the National Standard V was implemented in December 2017. 3. Different durability mileage: Compared to VI, the durability mileage for V increased from 80,000 kilometers to 160,000 kilometers. 4. Different particulate matter particle numbers: Compared to National Standard VI, National Standard V imposes stricter limits on nitrogen oxides, with a 25% reduction for gasoline vehicles and a 28% reduction for diesel vehicles.
As a long-time environmentally conscious car enthusiast, I believe the main difference between National V and National VI lies in their environmental protection levels. National V, implemented around 2017, was already stricter than previous standards, but National VI, introduced in phases starting from 2019, significantly raised emission limits. For example, it further reduces carbon monoxide and nitrogen oxides, cutting overall pollutant emissions by about 50%. This means National VI vehicles can better purify exhaust gases, mitigating smog and acid rain issues. I've personally noticed more National VI cars on the streets now, with urban air quality visibly improving. Driving a National VI car not only makes a greater environmental contribution but also saves fuel in the long run, as the new standard requires automakers to upgrade engine technologies—like adding particulate filters—to enhance efficiency. By choosing National VI, you're supporting sustainable development as the nation promotes green mobility. Remember to check the emission label when buying a car; opting for the newer standard creates a win-win—protecting the planet while saving money.
