What is the emission standard for a 2017 car?
3 Answers
17-year-old cars comply with the China 5 standard, which is the fifth stage of the national motor vehicle pollutant emission standards. The China 5 standard imposes stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emitted by motor vehicles. Methods to identify a China 5 compliant car: 1. Check the vehicle's fuel consumption label; 2. Check the vehicle's conformity certificate or environmental label; 3. Infer based on the time when the China 5 standard was implemented. The full implementation of the China 5 standard will significantly reduce motor vehicle exhaust pollution, achieving the goals of energy conservation, emission reduction, and green environmental protection. The high requirements of the China 5 standard necessitate comprehensive upgrades and modifications to the vehicle's powertrain by automakers to ensure truly clean emissions.
I specialize in researching automotive emission standards and often assist friends in analyzing such issues. Most vehicles produced in 2017 comply with the China 5 emission standard, as it was fully implemented nationwide that year, covering all new vehicle production. Emission standards significantly impact tailpipe pollutants like carbon monoxide and particulate matter. Compared to the previous China 4 standard, China 5 is more stringent, reducing pollutants by approximately 20%. When examining vehicle identification plates or environmental catalogs, I've observed that both joint-venture brands and domestic vehicles manufactured in 2017 predominantly meet China 5 standards. However, some advanced cities like Beijing, Shanghai, Guangzhou, and Shenzhen might have piloted the China 6 standard earlier. Therefore, if you're purchasing a used car, it's advisable to verify through the vehicle registration certificate or the DMV app. In terms of engine design, China 5-compliant vehicles feature improved catalytic converters, which can also enhance fuel efficiency. During routine maintenance, don't neglect air filter cleaning, as keeping the emission system unobstructed can prolong its service life.
I am a car owner who purchased a vehicle in 2017, and I confirmed at the time of purchase that it met the China V emission standard. The salesperson told me that emission standards directly affect license plate registration and traffic restriction policies. For example, China V vehicles can still drive in urban areas, offering much more flexibility than China IV vehicles. Checking the standard is simple: open the hood to check the Vehicle Identification Number (VIN), where the ending digits often correspond to the standard, or look at the environmental protection information section on the first page of the vehicle registration certificate. I also recommend downloading the Traffic Management 12123 app to verify and avoid being misled. China V vehicles generally have stable fuel consumption, making them suitable for family commuting, but don’t forget to undergo regular annual exhaust emission tests to ensure compliance. If you live in an area with heavy air pollution, China V might not be ideal—consider upgrading to China VI for more peace of mind and better environmental friendliness.
