What was the emission standard for cars in 2008?
2 Answers
In 2008, cars had either China II, China III, or China IV emission standards. Below is relevant information about emission standards: 1. Principle: Vehicle emissions refer to harmful gases such as CO, HC+NOx, and PM discharged from exhaust. These are harmful gases produced during the engine's combustion process. For example, CO is an intermediate product of incomplete fuel oxidation and is generated when oxygen is insufficient. High mixture concentration and uneven mixture can increase CO emissions. 2. Countermeasures: Vehicle emission standards are established to control pollutant emissions from cars. To curb the production of these harmful gases, automakers are encouraged to improve their products to reduce the source of these emissions, leading to the formulation of relevant vehicle emission standards.
As an average car owner, back in 2008 most vehicles complied with China III emission standards. I had just bought a car then, and remember seeing 'China III' on the registration certificate. It ran fine without major issues, but when selling it later I found it might face driving restrictions in big cities, with resale value dropping significantly. With growing environmental awareness, China III vehicles emit much higher pollutants like hydrocarbons compared to newer models - now upgraded to China VI. Older cars need regular annual inspections to ensure safe operation. If you own a 2008 vehicle, I suggest checking the owner's manual or entering the VIN online to verify emissions standards, don't wait until problems arise to find out.
