How to Determine the Vehicle's Emission Standard Level?

[Furtado]

Methods to identify a vehicle's emission standard level: You can check the car's manual, where it is usually annotated on the environmental green label and the vehicle parameters section of the vehicle certification. Vehicle emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot). To curb the production of these harmful gases and encourage automobile manufacturers to improve their products to reduce the source of these emissions, both Europe and the United States have established relevant vehicle emission standards. The European standards are the ones China references for vehicle emission regulations. Currently, domestically produced new vehicles will indicate the European emission standard that the engine's exhaust meets.
