Where Can I Check the Vehicle Emission Standards?
2 Answers
To check the vehicle emission standards, locate the model number on the nameplate under the co-pilot's door, then visit the Motor Vehicle Environmental Protection website. Enter the model number in the input box on the webpage, input the correct verification code, and click 'Query' to view the emission standards. You can also find other relevant information about the vehicle. Compared to the China 5 emission standard, the China 6 standard is more stringent in terms of testing criteria and pollutant emissions. The test cycle has been changed from NEDC to WLTC standards, with the addition of real-world driving emission tests. The pollutant limits are stricter, with China 6 being approximately 40% to 50% more stringent than China 5. The limits for CO and HC are one-third stricter compared to China 5.
To check my vehicle's emission standard, I usually start by carefully reviewing the vehicle license or registration certificate, which clearly states whether it meets China 5 or China 6 standards. There's often an environmental label with legible numbers stuck on the top right corner of the windshield—I make a habit of glancing at it before driving. Opening the engine hood reveals a detailed nameplate specifying compliance standards. If the information is unclear, I use the DMV app on my phone to enter the license plate for instant online results, saving me a trip. For older vehicles or missing documents, I consult repair shops or the original seller, as their systems keep backup records. Since emissions relate to environmental laws and annual inspections, I do a quick monthly check to ensure compliance and avoid future hassles.
