How to Determine Vehicle Emission Standards?
4 Answers
There are several methods to determine vehicle emission standards: 1. Vehicle environmental protection compliance label; 2. The starting page of the vehicle certification mark; 3. Estimate the vehicle's emission standard based on its manufacturing year; 4. Use the original or a copy of the motor vehicle registration certificate to inquire at the local vehicle management office. Here is additional information: 1. Emission standards refer to the levels of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot emitted from vehicle exhaust. 2. Vehicle emission standards are established to prevent pollution from the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.
To determine a vehicle's emission standard, here's a simple method for you. The most common way is to check the environmental label on the windshield or the inner side of the door – those small green icons usually indicate China 5 or China 6 standards. Alternatively, carefully examine the vehicle registration certificate near your car keys; there's a column specifying the emission level, clearly marked with numbers like China 1 or China 2. I often help friends check cars and find it especially crucial when buying used cars. Confirming the emission standard beforehand can save a lot of trouble, like avoiding high-emission older cars restricted in some cities – you don't want to end up unable to drive in. Also, jot down the vehicle's VIN number and enter it on the official website; the results will pop up instantly – official tools are really convenient. Understanding this can also save you money, as China 6 vehicles are more fuel-efficient with lower emissions, making them both eco-friendly and practical.
As someone who frequently repairs cars, I recommend starting with the vehicle's engine to determine the emission standard. Key points include checking the OBD diagnostic port to connect a device and read the data stream, where parameters will indicate the emission compliance level, such as Euro V or China VI labels. Alternatively, open the hood and look for the certification label near the engine, which displays the certification number and the standard corresponding to the production year. For example, new cars produced after 2020 generally comply with China VI standards and are equipped with numerous sensors to monitor exhaust emissions. At the repair shop, I test CO2 emissions and compare them with standard values to identify discrepancies. Don’t forget to check the fuse configuration in the fuse box, as China VI vehicles have more complex electrical circuits. Understanding some technical details can prevent mistakes during repairs and avoid misjudging emission issues that could lead to fines.
When my family and I went to the 4S dealership to choose a car, we learned how to determine the emission standards. The salesperson directly pointed it out to us: there's a small green label sticker on the rear bumper of the car, clearly marked with 'China V' or 'China VI' numbers—easy to understand at a glance. Alternatively, you can take a photo of the license plate with your phone and check it on an app, such as using Autohome's tool for free results. It's so simple that even a child can do it. This is related to the daily driving experience—China VI cars start without any strange odors, are quieter, more environmentally friendly, and save on fuel costs. When buying a new electric vehicle, you don't even need to worry about emissions, but for traditional cars, pay attention to the manufacturing year: most cars before 2017 are China V, while after 2022, they are uniformly China VI. Make sure to confirm this beforehand to avoid being checked on the road.
