Which Year's Cars Comply with China IV Standards?

[VanFrancisco]

Vehicles produced after July 1, 2011, comply with the China IV standard. The China V emission standard was implemented on July 1, 2017, so vehicles meeting the China IV emission standards were manufactured between 2011 and 2017. Here is some related information: 1. Emission Standards: As global environmental pollution becomes increasingly severe, countries worldwide are implementing stricter emission standards, which greatly benefit the protection of the Earth's environment. 2. Exhaust Treatment: Under strict emission standards, automakers actively develop new technologies to reduce engine exhaust emissions.

I remember when I was changing cars, I researched about China 4 standards. Basically, the China 4 standard refers to the nationwide emission requirements officially implemented on July 1, 2011, so many China 4-compliant cars were produced around 2011. However, some models might have started pilot programs as early as 2010, but the mainstream mass-produced vehicles came out in 2011. This standard mainly targets tailpipe pollutants like nitrogen oxides and particulate matter, which are much stricter than China 3. Nowadays, when buying a used car, you need to be careful because China 4 vehicles might face restrictions in emission control zones, affecting resale value. I recommend checking the vehicle's nameplate or VIN code to find the manufacturing date—if it's 2011 or later, it's most likely China 4. Anyway, with many places now pushing China 6 standards, China 4 cars are becoming less popular, but as a transitional phase, they still played a big role in reducing air pollution. If you're unsure, just go to a 4S dealership and have them check the emission label for you to avoid hassle.

The China 4 emission standard was fully implemented in 2011, and most vehicles produced during those years met this level. This standard significantly contributed to environmental protection by reducing harmful substances in exhaust emissions, such as carbon monoxide and sulfides. From a technical perspective, China 4 engines were designed with optimized combustion efficiency, driving industry-wide upgrades. If you're concerned about vehicle performance, China 4-compliant cars may have slightly better fuel efficiency, but due to higher requirements for parts, maintenance costs increased. I often enjoy delving into these details and consider 2011 a pivotal year, followed later by the introduction of China 5 and China 6 standards. To confirm if a vehicle meets China 4, the most straightforward method is to check the year information on the purchase invoice or the owner's manual.

Speaking of China 4, I consider its launch in 2011 as a significant milestone, as this wave of standards substantially reduced air pollution, with fewer smoggy days, for example. I know everyone worries about this year when buying a car, and indeed most cars produced after 2011 fall under China 4. A related issue is that these vehicles might face restrictions in urban low-emission zones, leading to a drop in resale value. But from an environmental perspective, it was a good starting point, with subsequent China 5 and China 6 standards further strengthening the requirements. It's advisable to prioritize newer emission grades when purchasing a car to avoid policy risks.
