China: New emission standards for passenger cars and heavy duty vehicles.

 

Chine is amending two new vehicle emission standards:

• National standard of the People’s Republic of China “Amendment to ‘Limits and measurement methods for emissions from light-duty vehicles (CHINA VI)’ (GB 18352.6—2016)
• National standard of the People’s Republic of China “Amendment to ‘Limits and measurement methods for emissions from diesel fuelled heavy-duty vehicles (CHINA VI)

The first one builds upon the China VI standard for light-duty vehicles by revising the definitions of emission control devices, defeat device, and auxiliary emission control devices. It strengthens the requirements for the sealing of type-approval vehicles and the reporting of failures in emission-related components covered under warranty. The amendment introduces provisions for the registration of CAL ID and CVN, specifies the equivalency conditions for type-approval extensions of hybrid electric vehicles, supplements the test procedures for vehicles with three or more axles, and further standardizes relevant technical testing requirements.

The second one builds upon China VI standards for heavy-duty vehicles by adding emission limits and testing requirements for hydrogen engines, specifying requirements for precious metal testing of three-way catalysts, revising the definition of failure strategies, improving the reporting provisions for failure information of warranty parts, and standardizing the relevant technical testing requirements.
