What is the equivalent of China IV standard?
3 Answers
China IV is the China 4 emission standard. Here is some relevant information about the China 4 emission standard: 1. This emission standard was implemented in 2010, and almost all vehicles produced after 2010 comply with the China 4 emission standard. 2. The China 4 emission standard is the fourth stage of the national motor vehicle pollutant emission standard. 3. The China 4 standard is based on the Euro 3 and Euro 4 vehicle emission standards. 4. China 1: Nationwide implementation on July 1, 2001; China 2: Nationwide implementation on July 1, 2004; China 3: Nationwide implementation on July 1, 2007; China 4: Nationwide implementation on July 1, 2010; China 5: Nationwide implementation on January 1, 2018; China 6: Implemented in some cities on July 1, 2019, with the latest nationwide implementation on July 1, 2020.
As an average car owner, I've been driving a China IV-compliant vehicle for nearly a decade. I remember when purchasing it, the salesperson mentioned that China IV is equivalent to the Euro IV standard, meaning their emission control levels are fundamentally aligned—such as limiting carbon monoxide and particulate matter in exhaust. The car feels quite clean to drive, starts smoothly, and has reasonable fuel consumption. However, it can't compare to later China V or China VI standards, which have stricter requirements and significantly lower pollutant levels. Nowadays, some areas in big cities restrict China IV vehicles from entering because their emissions still have some impact during urban smog episodes. Understanding that China IV is equivalent to Euro IV has been helpful when selecting used cars, as I know it meets standards in many regions abroad with good compatibility. Overall, China IV vehicles are simple to maintain, but for environmental reasons, I'm considering upgrading to a higher-standard model in the future.
I've spent many years in the automotive industry and have a thorough understanding of the China IV standard. It essentially mirrors the European Euro IV, meaning the pollutant emission limits are nearly identical, such as controlling nitrogen oxides to similar levels. The China IV standard was implemented around 2010, driving improvements in catalytic converters and prompting automakers to develop more efficient technologies. The benefit is that it enhanced the compatibility of domestic vehicles in international markets, allowing direct imports into the EU, for example. The downside, looking back now, is that its emission limits are less stringent than newer standards, making it easier to be phased out by environmental regulations. I recommend car owners pay attention to maintenance details, like regularly replacing air filters, to extend their vehicle's lifespan. Knowing it's equivalent to Euro IV makes it easier to select compatible parts or diagnose exhaust-related issues.
