What is the emission standard for 2009 vehicles?

[PaisleeDella]

2009 vehicles comply with either China III or China IV emission standards. Vehicles manufactured between July 2007 and September 2009 generally meet China III standards, while most vehicles produced after September 2009 adhere to China IV standards. Below is an introduction to automotive emission standards: 1. Automotive emission standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. Methods to check your vehicle's emission standard: (1) Check the label on the back of the vehicle's environmental protection compliance mark to easily identify the emission standard. (2) The vehicle certification document contains a section with detailed emission standard information, though it may not directly state "China III" or "China IV" but rather a series of characters. (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 inquiry.
