Cummins develops hydrogen combustion in China

A recent launch at Cummins’ East Asia Research & Devel­opment Centre showcased the company’s latest product strategy for China-based cus­tomers, focusing on the China debut of its 15-litre hydrogen internal combustion engine.

Meritor axles, Eaton Cum­mins Endurant transmissions and Cummins aftertreatment systems were also on display, highlighting the company’s commitment to provide a broader range of products, as well as full powertrain integra­tion capabilities.

Part of the company’s in­dustry-first fuel agnostic engine platform, Cummins’ 15-litre hydrogen engine, the X15H, features direct-injec­tion, lean-burn combustion, with ratings up to 542 hp and peak torque of 2600Nm. The zero-carbon fuel hydrogen engine can achieve brake thermal efficiency (BTE) up to 44 per cent with brake mean effective pressure (BMEP) of 22Bar, supporting diesel-like power and torque capability.

Jason Wang, Cummins vice-president and general manager of EBU China, said: “Achieving zero-carbon re­quires collaboration and joint innovation. Cummins has long-term partnerships with its Chinese customers which allows us to fully understand their business requirements and sustainability goals. The combination of in-depth mar­ket insights and a culture of innovation well-positions Cum­mins to develop the right solu­tions that support our custom­ers’ businesses while reducing environmental impact.”

The X15H hydrogen engine is based on familiar inter­nal-combustion engine tech­nology and can be integrated into a vehicle chassis without the need for a major product redesign. Its diesel-like per­formance means it’s a viable zero-carbon fuel option for many applications, including heavy-duty haulage and voca­tional trucks. Commonality be­tween the X15H and its diesel counterparts also supports ex­isting parts supply and mainte­nance practices.

Cummins is investing a to­tal of $150m in its East Asia Research & Development Cen­tre to enable further develop­ment of internal-combustion engine technology as well as zero-emissions products. The new facility covers an area of 78,000 square metres with 28 test cells and a building dedicated to zero-emissions power. The Centre has con­tributed to more than 50 new product introduction programs so far.
