How to Determine the Vehicle's Emission Standard (China Standard)?

[LaRyan]

Methods to determine the vehicle's emission standard (China Standard): 1. Check the label on the front windshield of the car, behind the environmental protection compliance sticker, which indicates the vehicle's emission standard; 2. Look at the vehicle conformity certificate, find the page for vehicle consistency or the page where the vehicle certificate number begins, as these sections contain details about the emission standard; 3. Estimate the emission standard based on the vehicle's manufacturing year; 4. Take the vehicle registration certificate to the local vehicle management office for verification—both the original and copies can be used to check the emission standard. Vehicle emissions refer to harmful gases such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) released from exhaust, all of which are produced during the engine's combustion process.
