[EllianaRose]

2009 cars comply with the China IV emission standard. Below is relevant information about the China IV standard: 1. Introduction: The China IV emission standard is the national fourth-stage motor vehicle pollutant emission standard. Automobile emissions mainly include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, it controls and reduces vehicle emissions to below specified limits. 2. Implementation timeline: In March 2009, the Industrial Policy Department of the Ministry of Industry and Information Technology convened a meeting with relevant enterprises to discuss the implementation of automobile emission standards (China III, China IV, China V), attended by major automotive manufacturers and engine producers. On December 21, 2010, the General Office of the Ministry of Environmental Protection of the People's Republic of China officially replied to the China Association of Automobile Manufacturers with the document Huan Ban Han [2010] No. 1390 "Reply Letter Regarding the Implementation Date of National Motor Vehicle Emission Standard Phase IV Limits".
