What is the emission standard for cars in 2008?
2 Answers
Most cars in 2008 comply with the China IV emission standard, which is the fourth phase of the national standard for motor vehicle pollutant emissions. The main pollutants from vehicle emissions include HC, NOx, CO, PM, etc. The standard aims to control and reduce these pollutants below specified levels through technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices. Methods to check a car's emission standard: 1. Look at the vehicle's environmental protection label, which has clear markings on the back; 2. Check the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center; 3. Bring the vehicle registration certificate to the DMV for inquiry; 4. Check the vehicle's factory certificate; 5. Make a rough estimate based on the year the vehicle was registered.
I remember that most cars in 2008 met the China III emission standards, which were officially implemented in July 2007. As a car enthusiast, I often pay attention to such changes. The China III standards were stricter than the previous China II, requiring reductions in carbon monoxide and nitrogen oxide emissions. Although not as environmentally friendly as today's new cars, it was a milestone of progress. Driving such cars can reduce air pollution to some extent, but regular maintenance cannot be neglected, otherwise it's easy to exceed the standards. To confirm whether your 2008 car meets China III, you can check the vehicle registration certificate or visit a 4S store to read the data with a computer diagnostic tool. The upgrade in emission standards is a good thing, promoting improvements in the automotive industry and contributing to urban blue sky projects.
