What does China V represent?
2 Answers
China IV refers to the vehicle engine system and emission standard tests being set up in a compatible manner. More details are as follows: 1. It is a transitional vehicle model. When the vehicle uses 93# China IV standard gasoline or diesel, the system recognizes it; when using 92# China V standard gasoline or diesel, the system detects the change, and the trip computer automatically adjusts the fuel injection volume and valves to achieve the optimal working state. As for whether it can be licensed, you need to consult the local motor vehicle management office, as policies vary from place to place. 2. The upper limit of sulfur content in China IV standard gasoline is 150mg/kg, in China V standard gasoline is 50mg/kg, and in China VI standard gasoline is 10mg/kg. 3. Due to the issue of fuel supply for vehicles, currently, light-duty diesel vehicles implement the third stage (China III) emission standard, while light-duty gasoline vehicles implement the fourth stage (China IV) emission standard.
As a veteran car owner who has driven for decades, I remember when emission standards were much looser. Cars would spew black smoke as soon as they started, causing significant pollution. Later, the country introduced the China V standard, the fifth phase of emission control, which requires strict control of tailpipe emissions from new vehicles, significantly reducing harmful substances like carbon monoxide and nitrogen oxides. Compared to the previous China IV standard, China V has stricter requirements and was fully implemented around 2017, mandating that all new vehicles meet the standard before hitting the road. I've noticed a significant improvement in air quality while driving—it's no longer as uncomfortable to breathe as it used to be. Nowadays, when buying a car, you must check for this certification; otherwise, some major cities may impose driving restrictions or deny registration. Upgrading older vehicles can be costly, but overall, encouraging environmental protection is a positive move, and it has spurred more innovation from automakers. Now, with the even more advanced China VI standard in place, I plan to prioritize China VI-compliant models when I upgrade my car. The continuous evolution of standards is making our lives healthier.
