China 6 Explained

China has been the largest vehicle market in the world since 2009 and the vehicle population, both light-duty and heavy-duty vehicle, continues to grow rapidly. At the end of 2019 China's vehicle population was over 250 million vehicles.

As a result, many of China’s cities have faced serious air quality issues. In order to minimize pollution generated by automobiles and improve air quality, the Ministry of Ecology and Environment (MEE) of the People’s Republic of China has implemented a series of legislation upgrades. The latest upgrade, known collectively known as China 6, aims to remove pollutants including particulate matter (PM) and oxides of nitrogen (NOx) from the air.

This latest legislation is composed of China VI, the emissions standard for heavy-duty vehicles, and China 6, the emissions standard for passenger cars and light-duty commercial vehicles.

The upgrades will be implemented in two phases—China 6a and China VIa went into effect on January 1, 2021 and July 1, 2021, respectively, and China 6b and China VIb go into effect in July 2023. During each phase, PM, NOx and other pollutant limits will become more stringent. Additionally requirements for emission system durability and onboard monitoring will be strengthened to ensure emissions reductions are maintained for the life of the vehicle.

To meet these limits, original equipment manufacturers (OEMs) are introducing new powertrain and aftertreatment systems which require new engine oil technology to operate efficiently and reliably as intended.

In addition to the implementation of China 6, Fuel Consumption Legislation Stage III came into effect in 2020, requiring a 15% reduction in fuel consumption versus Stage II. Further fuel consumption reductions will be phased in during the coming years.
