How to Distinguish Between China IV and China V Vehicle Standards?

The methods to distinguish between China IV and China V vehicle standards are: 1. Check the corresponding standard number on the vehicle conformity certificate. The emission standard number for China IV is GB18352.32005, and for China V is GB18352.52013; 2. Check the environmental information accompanying the vehicle list; 3. Check the posted vehicle fuel consumption label; 4. Check the vehicle qualification certificate; 5. Query the vehicle's emission standard on the Motor Vehicle Environmental Protection Website. Vehicle emission standards refer to the regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and carbon smoke emitted from vehicle exhaust.

I do a lot of car repairs, and the method to distinguish between China IV and China V emission standards is actually quite straightforward. The quickest way is to check the vehicle's nameplate label, usually located in the engine compartment or on the door frame, which will clearly indicate 'China IV' or 'China V'—the Roman numerals represent the emission standard. If the label is faded, don't worry—look for the vehicle conformity certificate or the environmental information card, documents that come with the car at purchase and will definitely have the details. Another method is to check the Vehicle Identification Number (VIN), visible at the lower left corner of the windshield. Inputting it online will quickly display the emission level through many official tools. I recommend paying attention to the vehicle's year—2010 to 2013 was the transition period for China IV, and most new cars after 2013 adopted China V. Distinguishing clearly is crucial for environmental protection—China V cars pollute less, comply with more cities' traffic restriction policies, saving you money and protecting the environment.

From a technical perspective, the main difference between China IV and China V standards lies in emission limits – China V imposes stricter controls on nitrogen oxides (NOx) and significantly reduces exhaust emissions. My suggestion is to first check the vehicle's manufacturing year for identification: most pre-2010 vehicles are China IV, while newly manufactured vehicles after 2013 are generally China V. The emission standard is clearly marked on the vehicle registration certificate or sales invoice for instant recognition. The verification process is straightforward – consult dealerships or use automotive apps to check the VIN code for immediate results. I've seen owners neglect this, only to face inspection failures later, causing unnecessary trouble. Knowing your vehicle meets higher emission standards means greater reliability, especially when driving in areas with air quality management regulations – it gives extra peace of mind.

When buying a used car, distinguishing between China IV and China V emission standards is crucial. I recommend first checking the production date on the vehicle registration certificate - cars manufactured before 2013 are likely China IV, while most after that are China V. The environmental protection sticker in the corner of the windshield will also have Roman numeral markings indicating China IV or V. Don't skip steps - simply search the vehicle's VIN code in a mobile app for clarification, or verify it on the environmental protection bureau's website. This identification method helps avoid purchasing older cars with high restriction risks and ensures better resale value. Choosing a China V compliant car will save you a lot of hassle in the long run.

As an environmentally conscious individual, I believe distinguishing between China IV and China V emission standards promotes green mobility. China V vehicles have lower emissions, which benefits air quality improvement. A simple way to identify is to check the environmental label sticker on new cars, commonly found at the lower edge of the windshield—it clearly states the standard. The vehicle manual or manufacturer-provided emission catalog also contains this information. Many cities now restrict China IV vehicles from entering urban areas, so I use apps to scan VIN codes to verify the standard, ensuring my driving doesn't burden the environment. Choosing higher emission-standard vehicles benefits both personal health and the community.
