What is the emission standard for vehicles from 2017?
2 Answers
Vehicles from 2017 comply with the China V emission standard. The full name of the China V standard is the National Fifth Stage Emission Standard for Motor Vehicle Pollutants. The emission control level of the China V standard is equivalent to the Euro 5 emission standard currently implemented in Europe. The European Union has been enforcing this standard since 2009, which imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. From China I to China IV, each upgrade in the standard reduces vehicle pollution by 30% to 50%. Compared to the China IV standard, the China V standard reduces nitrogen oxide emissions from light-duty vehicles by 25% and from heavy-duty vehicles by 43%. Effects of implementing the China V standard: It promotes the improvement of domestic gasoline and diesel quality for vehicles, contributes to the reduction of pollutants from new vehicles, and improves the emission conditions of a large number of in-use vehicles.
I've driven quite a few 2017 model year cars, most of which were compliant with the China 5 emission standards, as the China 6 standards were still in preparation at that time, and new cars rolling off the production line generally adhered to this standard. If you're unsure about your car's emission standard, the simplest way is to check the vehicle registration certificate or the environmental label, which usually states 'China 5'; alternatively, you can use a mobile app to look up the VIN code for confirmation. The China 5 standard is much cleaner than the older standards, significantly reducing emissions of nitrogen oxides and particulate matter, which is beneficial for urban air quality. However, post-2019, new cars started adopting the China 6 standard, which is even more environmentally friendly. I recommend paying attention to regular maintenance, such as changing the air filter periodically, as this can help reduce pollution emissions. When buying a used 2017 car, it's especially important to check this aspect, because if the emissions don't meet the standard, it can cause issues during the annual inspection and even affect the transfer of ownership. In summary, 2017 cars are indeed China 5 compliant, so there's no need to worry too much—daily driving shouldn't be a problem, but it's good to be environmentally conscious.
