What is the emission standard of Santana 3000?
2 Answers
Santana 3000 complies with China IV emission standard. Below is relevant information about China IV: 1. China IV emission standard is the fourth-stage national standard for motor vehicle pollutant emissions. Automotive pollutants mainly include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). Through technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, it controls and reduces vehicle emissions below specified limits. 2. Vehicles produced between 2011 and 2017 generally meet China IV standard. China IV requires approximately 60% lower emissions of various pollutants compared to China III. 3. To ensure vehicles stably meet emission limits during use and maintain durability of emission control performance, additional requirements were introduced for On-Board Diagnostics (OBD) systems and in-use vehicle compliance.
I've been driving a Santana 3000 for many years, a classic China II emission standard vehicle, as my 2005 model always bears the China II label during annual inspections. Back then, China's emission standards were transitioning from China I to China III, and the Santana 3000 was caught in between, with its engine and exhaust system not meeting the later China III requirements. Nowadays, driving it feels somewhat restricted, especially in big cities like Beijing where older vehicles face occasional traffic restrictions, forcing me to avoid peak hours. Fortunately, it's durable—with proper maintenance, it can still last a few more years. However, its fuel consumption is higher than newer models, and emissions fall short of modern standards. I recommend owners check their environmental stickers to confirm the version; occasionally upgrading the catalytic converter might help slightly, but ultimately, it remains a relic of the older car era.
