What is the emission standard for a car purchased in 2009?

[StAngelo]

Cars from 2009 are either China III or China IV. To determine the exact emission standard, you need to check the brand and specific model of the car purchased in 2009. Additional knowledge: Implementation dates of some automobile emission standards: 1. China III: GB18352.3-2005 "Limits and measurement methods for emissions from light-duty vehicles (China III, IV stages)", partially equivalent to Euro III, implemented in 2007; 2. China IV: Partially equivalent to Euro IV, implemented in 2010. The China III and IV emission standards for light-duty vehicles do not have identical pollutant emission limits to Euro III and Euro IV standards. 3. China V: GB18352.5-2013 Limits and measurement methods for emissions from light-duty vehicles (China V stage), implemented from January 1, 2018.
