What is the emission standard for 2009 cars?
2 Answers
2009 cars comply with the China IV emission standard. Below is relevant information about China IV: 1. Introduction: The China IV emission standard is the fourth-phase national standard for motor vehicle pollutant emissions. Automobile emissions mainly include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. Through 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 below specified limits. 2. Issues: From a management perspective, local governments clearly dominate in negotiations with automakers - non-compliant vehicles cannot be sold, which has caused significant anxiety among manufacturers with "China III" models. However, local governments may be at a disadvantage when negotiating with giants like Sinopec and PetroChina.
As someone familiar with automotive details, I understand that most cars produced in China in 2009 complied with the China III emission standards. China's emission standards were gradually upgraded in the 2000s: China I was implemented around 2000, China II was promoted in 2004, and China III became the primary standard in 2007 until it was replaced by China IV in 2010. The year 2009 was right in the transition period, so newly manufactured vehicles were predominantly China III. In some major cities like Beijing and Shanghai, due to early policy adoption, certain models might have met China IV, but overall, China III was the mainstream. To confirm this, you can check the explicit labeling on the vehicle registration certificate or the environmental protection label on the front windshield. Many car owners at that time overlooked the standards, but today, traffic restriction policies, such as bans in urban core areas, have made this information crucial. Understanding it helps ensure smooth vehicle inspections and avoids unnecessary trouble, as differences in emission standards impact air quality and daily use.
