What is the emission standard for cars from 2018?

[VonSadie]

18-year-old cars comply with China V emission standard. Here is the relevant introduction: 1. China V introduction: The National Fifth Stage Motor Vehicle Pollutant Emission Standard, abbreviated as "China V Standard", has an emission control level equivalent to the European Union's currently implemented Euro 5 emission standard. The EU has been implementing it since 2009, imposing stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emitted by motor vehicles. 2. 10% reduction in pollutant emissions: Compared to the China IV gasoline standard, the China V standard significantly reduces sulfur content. According to calculations by the National Standards Committee, the implementation of this standard will greatly reduce vehicle pollutant emissions. It is estimated that in-use vehicles can reduce nitrogen oxide emissions by approximately 300,000 tons annually, while new vehicles can cumulatively reduce nitrogen oxide emissions by about 90,000 tons over five years.

I often talk to my friends about car emissions. Cars produced in 2018 mostly comply with the China V emission standard, simply put, the fifth-stage emission standard. This is because the country mandated that new cars meet the China V standard starting from 2017, while the China VI standard wasn't implemented until July 2019. I've driven a China V-compliant car, and its exhaust pollution is much less than older cars, with significant reductions in nitrogen oxides and other pollutants, making it better for the environment. However, the China VI standard is more advanced, so if you're buying a used car, you should check the standard number on the registration certificate. Regular car maintenance, such as timely air filter changes, makes it easier to pass emission tests.

When buying a car, I paid special attention to emissions. Based on my research, most cars from 2018 were China V compliant. National policy required an upgrade to China VI in 2019, so new cars purchased at that time were all China V standard. You can easily verify this: check the registration certificate or green book for the emissions identification section, or scan the VIN using a WeChat mini-program for direct lookup. Don’t underestimate this—it affects licensing and traffic restrictions. In cities like Beijing and Shanghai, some zones allow access for China V cars, making them more convenient than older standards. For daily driving, maintaining the engine properly helps minimize emission-related issues.

I've been researching vehicle standards for years. In 2018, most cars still complied with China 5 emissions. The China 6 standard was introduced in 2019, before which China 5 was the dominant standard. This has helped improve air quality, with pollutant levels significantly reduced. To confirm, just check the data through the annual exhaust emission test - it's super simple.

I often discuss environmental policies with others. The emission standard for newly produced cars in 2018 was China V. The national emission standards evolved from China I to China VI by 2019, with China V dominating during the transition period. It reduced pollutants like carbon monoxide, making vehicles cleaner compared to older ones. However, China VI further optimized these standards, so now when buying a used 2018 car, you need to check the green certificate for confirmation. Understanding these standards can also help you plan routes in urban restricted zones.

I've been repairing cars for many years. Cars manufactured in 2018 are 99% compliant with China V emission standards, and their exhaust test values are easier to control compared to older standards. You can check the vehicle nameplate or registration book yourself, where it's clearly marked. Emissions are related to the annual inspection pass rate, and I've seen cases where owners neglected maintenance and ended up with excessive exhaust emissions. I recommend regularly changing the oil filter and not missing inspections to ensure smooth driving.
