What is the emission standard for the 2013 Teana?
2 Answers
The 2013 Teana complies with the China IV emission standard. Below is a detailed introduction to the implementation timelines of some automotive emission standards: China III emission standard: The specific implementation dates were July 1, 2009, for light-duty diesel vehicles, July 1, 2010, for heavy-duty gasoline vehicles, July 1, 2008, for heavy-duty gas vehicles, and July 1, 2008, for heavy-duty diesel vehicles. China IV emission standard: The nationwide implementation dates were July 1, 2013, for light-duty diesel vehicles, July 1, 2013, for heavy-duty gasoline vehicles, January 1, 2011, for heavy-duty gas vehicles, and July 1, 2013, for heavy-duty diesel vehicles. China V emission standard: The nationwide comprehensive implementation began on July 1, 2017. Compared to the China IV standard, it reduces nitrogen oxide emissions by 25% and introduces stricter PM (particulate matter) emission limits.
As someone who has been keeping an eye on new car developments, I noticed that the 2013 Teana model was launched right when the China IV emission standards were being implemented. During that period, China IV became mandatory nationwide, and automakers had to make upgrades to comply. The China IV standards required significant reductions in tailpipe pollutants, with stricter controls on hydrocarbon and nitrogen oxide emissions. Compared to the previous China III vehicles, it was equipped with a more efficient three-way catalytic converter, allowing the engine to run cleaner. However, this also brought some maintenance challenges, such as potential catalytic converter clogging after a few years if not properly maintained, which could affect emissions tests during annual inspections. I recommend that owners now pay extra attention to the environmental labels or visit a 4S dealership to scan vehicle information with a diagnostic tool to confirm the standard details. Overall, China IV vehicles were considered mainstream in 2013, offering benefits for both the environment and fuel efficiency, but owners should be aware that some major cities may have minor traffic restrictions for older emission-standard vehicles.
