Hydrogen-fueled Engine Yuchai YCK16H ignites

Yuchai YCK16H hydrogen-fueled engine was successfully ignited in Yulin, Guangxi.

Yuchai YCK16H hydrogen-fueled engine, with a displacement of 15.93 litres and a maximum horsepower of 560 hp, is the largest hydrogen-fueled engine with the largest displacement and horsepower in China.

The successful ignition of Yuchai YCK16H marks another solid step forward for Yuchai in the zero-carbon energy power system segment.

Li Hanyang, Secretary of the Party Committee and Chairman of Yuchai Group, ignited YCK16H. He said that the new energy engine field has developed rapidly in recent years. Yuchai, as a manufacturer of traditional engines, has taken the initiative to embrace clean-energy engines, made breakthroughs in clean-energy engines, and supported China’s strategic goals of “carbon peaking and carbon neutrality” with Yuchai’s responsibility and commitment.

In December 2021, Yuchai successfully ignited China’s first hydrogen-fueled engine YCK05H oriented to urban buses, municipal administration, sanitation, logistics and distribution fields, driving China’s internal combustion engine industry into the zero-carbon energy power system segment, and marking the start of the R&D of hydrogen-fueled engines for commercial vehicles in China.

After completing the development of the light-duty hydrogen-fueled engine platform, Yuchai has launched YCK16H heavy-duty in-cylinder direct injection hydrogen-fueled engines, making Yuchai the only professional power system supplier covering light-duty and heavy-duty hydrogen-fueled internal combustion engines and fuel cell systems in the field of hydrogen energy in China.

The ignited YCK16H adopts advanced fuel high-pressure common rail, high-pressure in-cylinder direct injection technology and dual-channel turbocharging technology, which can realize homogeneous combustion or stratified combustion in the cylinder as required, featuring stronger power performance, higher thermal efficiency and better stability.

The platform has high adaptability to fuel purity and can be adapted to fuels prepared by grey hydrogen, green hydrogen, methanol-produced hydrogen, and other means. The fuel supply can be freely combined according to user needs and the basic conditions of fuel production, storage and transportation, which is a highly adaptable, flexible and controllable zero-carbon/low-carbon power solution.

To solve the problem of the relatively small power per liter of hydrogen-fueled engines, Yuchai chose the YC16H platform, which has higher horsepower but is smaller and lighter than similar products, and can be widely used in scenarios such as 49T tractors and other heavy commercial vehicles and distributed energy sources. tion engines.

It’s said that the natural gas engine YCK15N developed based on this platform has completed bench tests and vehicle road tests, and is expected to be put into mass production by the end of 2022. The verification results show that YCK15N has higher reliability, the number of cylinder head low-cycle fatigue cycles increases by 2.35 times, and B10 reaches 1 million kilometers.
