Santana 3000 complies with China IV emission standard, which is the fourth stage national standard for motor vehicle pollutant emissions. Below are the main pollutants emitted by vehicles: 1. Hydrocarbons. 2. Nitrogen oxides. 3. Carbon monoxide and particulates. Here are methods to control and reduce vehicle emissions: 1. Active layer of catalytic converters. 2. Catalytic secondary air injection. 3. Catalytic exhaust gas recirculation system with cooling devices. Extended information on how to check a vehicle's emission standard: 1. Check the vehicle's environmental protection label, which has clear markings on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center or bring the vehicle registration certificate to the DMV for inquiry. 3. For new vehicles, refer to the vehicle's factory certificate. 4. Make a rough distinction based on the year the vehicle was registered.

As a former Santana 3000 owner, I can share personal experience. This car was launched in 2004, so its emission standard was usually China II. Vehicles from that era didn't focus much on environmental protection, with high exhaust emissions. When I drove it, I frequently encountered urban traffic restrictions, especially in big cities like Beijing where it was directly prohibited from entering within the 3rd Ring Road. China II standard vehicles emit high levels of carbon dioxide and nitrogen oxides, which are environmentally unfriendly. However, they can still be found in the used car market today—cheap, durable, and with low repair costs. But if buying used, it's best to check the vehicle management office's registration records or emission inspection stickers to confirm the emission standard to avoid disadvantages.

I've been driving for over 20 years. The Santana 3000 from that era, I recall, was compliant with China II emission standards, just like the old Santana models from the same period. Emission standards have become increasingly stringent from China I to China VI. China II vehicles are considered low-end in terms of emission control, featuring simpler exhaust systems, higher pollution levels, and louder noise. The upside is their stable mechanical structure, fuel efficiency, and cost-effectiveness, along with easy maintenance. Nowadays, many cities impose driving restrictions, and these older vehicles require regular annual inspections. They often fail the exhaust emission tests. I recommend that owners purchase an emission tester for home self-checks or visit professional garages to upgrade the catalytic converter to extend their vehicle's usability.

The Santana 3000 generally meets China National II emission standards, which are relatively low and result in higher pollutant emissions affecting air quality. I believe driving such a car is irresponsible towards the environment, and it's better to switch to a newer model. Emission levels are distinguished by the year of production; for example, most cars produced in 2004 are China National II compliant. The checking method is quite simple: look at the model approval number on the registration certificate or scan the VIN code with a mobile app to check the historical records.
