China 5 emission standard is marked with "V", while China 6 emission standard is marked with "Ⅵ", both using Roman numerals for identification. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number. For used cars, you can check the environmental protection website using the vehicle's complete model number. The following information is about China 5 and China 6 standards: 1. The biggest difference between China 5 and China 6 emission standard cars is the three-way catalytic converter. China 6 emission standard cars use a more efficient three-way catalytic converter, which ensures the vehicle's exhaust emissions meet the China 6 standard. 2. China 5 emission standard is the fifth stage national standard for motor vehicle pollutant emissions. It reduces nitrogen oxides and particulate matter emissions by 25% and 80% respectively, lowering the overall emissions of China 5 cars by 10%-15%. The China 6 emission standard imposes even stricter regulations on pollutant emissions.
