What is the emission standard for vehicles in 2009?

[Raymond]

Vehicles in 2009 are either China III or China IV emission standard. The specific emission standard depends on the brand and model of the vehicle in 2009. Methods to check the vehicle emission standard: 1. Take the vehicle registration certificate to the vehicle management office for inquiry; 2. Log in to the vehicle environmental protection website for inquiry; 3. Check the environmental protection label on the annual inspection. Vehicle emission standards refer to the regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, and PM (including particles, carbon smoke, etc.) emitted from vehicle exhaust. Since vehicle exhaust emissions mainly occur between 0.3 meters and 2 meters, they cause severe harm to human health. Controlling vehicle exhaust pollution has become a major task for environmental protection departments, automobile manufacturers, and all sectors of society.
