What is the China VI Standard?

[NadiaDella]

China VI is the China 6 standard. The following is an introduction to China 6 vehicles: China VI: Full name: National Sixth Stage Emission Standards for Motor Vehicle Pollutants, which refers to the emission standards for vehicle exhaust. Currently, China is implementing the China 5 emission standard; the China 6 emission standard is 40%-50% stricter than China 5, comparable to U.S. standards, and can be considered one of the most stringent emission standards globally. The China 6 emission standard is implemented in two phases: China 6a and China 6b, with China 6b being stricter than China 6a. Implementation Requirements for China VI: According to national requirements, the China 6 standard is implemented in two phases. Starting from July 1, 2020, all light-duty vehicles sold and registered must comply with the "China 6a" limit requirements; from July 1, 2023, all light-duty vehicles sold and registered must comply with the "China 6b" limit requirements.

After driving for over a decade, I finally grasped the China VI emission standard. It mandates cleaner vehicle emissions by strictly limiting pollutants like carbon monoxide, hydrocarbons, and particulate matter. Compared to the previous China V standard, it imposes significantly stricter exhaust pipe emission limits—approximately 30% lower. Nowadays, 4S dealerships strongly recommend China VI-compliant models since non-compliant vehicles can't be registered in urban areas. Mechanics emphasize using genuine filters during maintenance to avoid malfunctions. Environmentally beneficial, it noticeably improves urban air quality with fewer hazy days. Long-term, it pushes automakers to develop high-efficiency engines but accelerates older vehicle phase-outs, potentially impacting used car values. Remember its nationwide rollout in 2019, implemented in phases across provinces.

I often ponder automotive technology, and the China VI standard is quite intriguing. It's essentially equivalent to the European Euro VI, with specific limits for different vehicle types. For instance, nitrogen oxide emissions from diesel vehicles must be kept below 0.08 grams per kilometer. Technically, it requires advanced exhaust treatment systems like Gasoline Particulate Filters (GPF) and Selective Catalytic Reduction (SCR), which significantly improve engine efficiency. In daily driving, fuel consumption is slightly reduced, benefiting the environment with lower air pollutant emissions. However, costs have risen, leading to slightly higher new car prices and more complex repairs. The future trend is transitioning to electrification, where China VI serves as a crucial bridge.

In simple terms, the China VI emission standard means stricter vehicle emissions. It sets limits on indicators like carbon monoxide and PM2.5, with different requirements for gasoline and diesel vehicles. After implementation, air quality improves slightly, reducing urban smog. As car owners, we should pay attention to purchasing China VI-compliant models to avoid mistakes. For maintenance, regular inspection of the exhaust system is necessary to prevent blockages. This standard applies equally to all automakers, forcing technological upgrades while also promoting green transportation.

I know a bit about environmental policies. The China VI standard was introduced by the government to improve air quality. It sets stricter limits on pollutants like hydrocarbons and nitrogen oxides compared to China V. The benefits are numerous—halving exhaust emissions and promoting healthier breathing. However, it poses significant challenges for car manufacturers, such as requiring additional exhaust purification devices. Consumers may need to spend more when buying cars, but long-term fuel savings are expected. Implementation is divided into two phases: nationwide coverage by 2020 and 2023, with possible subsidies during the transition period. In the future, it will align with the development of electric vehicles for greater sustainability.
