What is the emission standard for a 2004 vehicle?
2 Answers
A 2004 vehicle belongs to either China II or China III emission standards. Below is an introduction to the implementation timeline of emission standards: 1. China I standard: Nationwide implementation on July 1, 2001, mainly targeting restrictions on carbon monoxide, hydrocarbons, and particulate emissions. 2. China II standard: Nationwide implementation on July 1, 2004, requiring a 30% reduction in carbon monoxide and a 55% reduction in hydrocarbons and carbon oxides compared to China I. 3. China III standard: Nationwide implementation on July 1, 2007, requiring a 40% reduction in total pollutant emissions compared to China II. 4. China IV standard: Nationwide implementation on July 1, 2010, requiring a 50% to 60% reduction compared to China III. 5. China V standard: Nationwide implementation on January 1, 2018, requiring a 25% reduction in nitrogen oxide emissions compared to China IV.
For cars produced in 2004, having worked in the auto repair industry for years, I've seen plenty—they typically fall under the China I emission standard. That's because China I was implemented starting July 2000, while China II didn't come into effect until July 2005, with a transition period in between. Back in '04, many models couldn't meet the new requirements yet, emitting significantly higher levels of exhaust compared to today's China VI vehicles, which are far more eco-friendly and efficient. Want to confirm your car's standard? Check the vehicle's identification plate or enter the VIN on the traffic bureau's website. For older cars like these, I recommend regular emissions testing to avoid getting caught by urban driving restrictions. Poor emissions not only affect annual inspections but may also hike up repair costs—so maintaining the air filter and catalytic converter is crucial. After all, a car over a decade old needs extra care; addressing issues early prevents breakdowns and ensures both safety and environmental compliance.
