China Yuchai introduces China's largest and highest horsepower H2 engine

China Yuchai International through its main operating subsidiary, Guangxi Yuchai Machinery Company announced its latest technology advancement, the new heavy-duty H2 engine, YCK16H.

With a displacement of 15.93 liters and a maximum horsepower of 560 horsepower, YCK16H is the largest and most powerful H2 internal combustion heavy-duty engine being launched in China.  Different from its peer products in the marketplace, the YCK16H is smaller in size and lighter in weight but produces larger horsepower that can be widely used in various heavy-duty commercial vehicles such as the 49T semi-trailer and distributed energy resource applications.

YCK16H features a proprietary smart engine control system along with its advanced high-pressure common rail, high-pressure direct injection and twin scroll turbocharger technologies enabling stronger power, higher thermal efficiency and better combustion stability.

This platform is designed with high adaptability for fuel concentration, which allows the engines to operate with different H2 fuels such as grey H2, green H2 and H2 from methanol.

The introduction of the heavy-duty YCK16H engine follows the successful launch of China's first H2-fired engine the YCK05H in December 2021. The light-duty YCK05H is designed for the urban bus, municipal administration, sanitation and logistics markets.

Weng Ming Hoh, President of China Yuchai said, "New energy technologies are rapidly evolving and our new H2-fired YCK16H engine marks another milestone on our zero-carbon energy track. Our new energy engine technologies support China's long-term strategic plans to lower emissions."
