What is the emission standard for 2013 models?

[VanRicardo]

Most 2013 models comply with the China III emission standard, while some models meet the China IV standard. The China III emission standard refers to the National Phase III Emission Standard. Vehicles meeting China III standards will be subject to mandatory scrapping after the implementation of China VI standards, with the specific timing determined by regional enforcement policies. Vehicle emissions encompass exhaust emissions, evaporative emissions, and crankcase emissions. Exhaust emissions include CO, HC, NOx, sulfur compounds, lead compounds, and particulate matter discharged from the engine exhaust pipe. Evaporative emissions refer to harmful fuel vapors from the fuel tank, fuel supply system, lubrication system, as well as solvent vapors from automotive coatings. Crankcase emissions denote harmful substances like HC, CO, NOx, and sulfur compounds leaking from the crankcase ventilation port.
