What is the emission standard for a 10-year-old car?
2 Answers
2010 cars could meet either China IV or China III emission standards, depending on the specific vehicle model. Additional information: 1. Vehicle emission standards can be roughly estimated based on the registration year: (1) Cars registered before 2005 are generally China II standard. (2) Cars registered before 2007 are mostly below China IV standard (China II or China III). For cars registered in 2007, some meet China III while others meet China IV. (3) Most cars registered after 2008 meet China IV standard. 2. Differences between China II, China III and China IV: (1) There's no significant difference between China II and China III vehicles, mainly just variations in displacement, with no changes to the core vehicle functions. (2) The implementation of China IV emission standard has effectively reduced emissions of pollutants including HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter).
If you ask about the emission standard of a car from 10 years ago, it usually refers to vehicles produced around 2010. At that time, many cars already met the China IV standard. Having researched automotive emission standards for many years, I believe China IV was widely implemented in 2010, as China began piloting it in multiple regions nationwide from 2009 and officially rolled it out comprehensively in 2011. Compared to the previous China III standard, it reduced pollutants by approximately 30%, making it more environmentally beneficial. Checking your car's emission information is simple—just look at the registration date and standard column on the vehicle license, or enter the VIN number online to find out. Older cars, if not properly maintained, are prone to emission system failures that can affect test results, so regular maintenance of exhaust components is essential. Remember, understanding this is beneficial for both used car transactions and environmental policies—don't overlook this small detail.
