What does China V mean?

China V refers to the National Fifth Stage Emission Standard for Motor Vehicles, also known as the China V standard. The methods to check a vehicle's emission standard are: 1. Check the motor vehicle conformity certificate; 2. Look for the vehicle packing list; 3. Log in to the motor vehicle exhaust pollution supervision and management website; 4. Check the back of the environmental protection label on the car's front windshield; 5. Bring the vehicle registration form to the vehicle management office for inquiry. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as the active layer of catalytic converters, secondary air injection, and exhaust gas recirculation systems with cooling devices, these vehicle emission pollutants are controlled and reduced to levels below the specified standards.
China 5 is essentially the fifth phase of the national motor vehicle pollutant emission standards, simply put, it's a set of rules limiting vehicle emissions. Officially rolled out for full implementation in 2017, it requires new vehicles to meet lower emission levels at production, strictly controlling harmful substances like carbon monoxide and nitrogen oxides. Compared to the previous China 4 standard, China 5 is much stricter, pushing automakers to innovate engine technologies, such as introducing better catalytic converters. Personally, I think this is very necessary as it reduces urban smog and promotes green transportation. While daily driving might not feel directly different, its environmental benefits are significant; choosing China 5-compliant vehicles also makes passing license plate inspections easier. In the long run, the country's gradual upgrade to China 6 and China 7 standards is the trend, and each of us can contribute to environmental protection by purchasing high-efficiency vehicles.
