How to Check Whether a Car Meets China 5 or China 6 Emission Standards?

[VanEmmett]

To check whether a car meets China 5 or China 6 emission standards, you can follow these methods: 1. Check the vehicle's factory certificate. 2. Refer to the vehicle's environmental standard list. 3. Review the vehicle conformity certificate. China 5, fully named as the National Fifth Stage Emission Standard for Motor Vehicles, and China 6, fully named as the National Sixth Stage Emission Standard for Motor Vehicles, both regulate the permissible levels of harmful gases emitted from vehicle exhaust, including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), particulate matter (PM), and soot. The differences between China 5 and China 6 are: 1. Different CO emission requirements: China 5 allows 1000 milligrams per kilometer, while China 6 reduces it to 500 milligrams per kilometer. 2. Different PM emission requirements: China 5 permits 5 milligrams, whereas China 6 lowers it to 3 milligrams.
