A standard drafting team consisting of experts from the Vehicle Emission Control Center (VECC) of the Chinese Research Academy of Environmental Sciences, Beijing Institute of Technology and other institutions visited Yuchai. They held a special forum with technical teams from Yuchai and Dongfeng Liuzhou Motor. In-depth exchanges were conducted on core topics including the latest emission regulatory policies of China National Stage VII for commercial vehicles and China National Stage V for non-road mobile machinery, technical implementation difficulties and industry development trends, jointly promoting the low-carbon, green and high-quality development of the internal combustion engine industry.
Experts from the VECC standards drafting team elaborated on the formulation logic, core indicators, implementation plans and supervision requirements of the China National Stage VII emission standards for commercial vehicles and China National Stage V emission standards for non-road mobile machinery. They systematically shared key industry priorities such as coordinated control of mobile carbon and pollutant emissions, deep emission reduction and upgrading of testing technologies. The team clarified stricter control standards and development orientations for internal combustion engine emissions in the new phase, pointing out a compliance-oriented development path for enterprises to advance technological iteration.

Yuchai presented its achievements in R&D of emission compliance technologies, product iteration and upgrading, and the development of a green manufacturing system. As a pioneer in the low-carbon and green transformation of China's internal combustion engine industry, Yuchai has long focused on innovations in low-carbon and eco-friendly power technologies. It has proactively carried out R&D and product upgrades in advance to meet China National Stage VII and Non-road China National Stage V standards, continuously optimized engine aftertreatment systems and combustion control technologies to fully comply with the latest environmental regulations. Meanwhile, the company actively explores integrated development paths for conventional and new energy power solutions, laying a solid foundation for the green transformation of the industry.
During the forum, participants held in-depth discussions on key issues including technical challenges, testing and certification, and industrial application bottlenecks arising from the release and enforcement of the new emission standards. They reached a preliminary consensus on regular follow-up technical exchanges, coordinated standard research and joint technological innovation cooperation.This exchange effectively bridges the communication gap between regulatory research institutions and industrial practitioners. It provides strong support for enterprises across the industry to accurately adapt to the latest environmental regulations, accelerate the iteration of high-end green products, and advance the low-carbon transformation of the internal combustion engine sector.
