Cummins B6.7 hydrogen engine

Cummins will display its next-generation B6.7H hydrogen engine to the construction industry for the first time at the Intermat show in Paris, France in April (24th to 27th).  

Following on from the agnostic 15-litre engine display at last year’s ConExpo event, Cummins will exhibit the new B6.7 engine platform with the same capability. This design enables a consistent mounting and space claim for clean diesel, biodiesel, natural gas and hydrogen fuels. The main engine block remains the same with the head and the fuel system being the key changes. They can be installed in the same equipment as today’s diesel while also using the same transmission, cooling systems, and hydraulic systems, reducing complexity for equipment manufacturers and their customers. Maintenance practices and costs are also comparable to diesel engines. 

Visitors to Intermat will be able to see Cummins’ B6.7H hydrogen engine aimed at a wide range of off-highway machinery, with a top rating of 290hp (216kW) and an impressive peak torque of 1,200Nm targeted for Stage 6/Tier 5. Also on display at Intermat will be Cummins’ on-board fuel storage, a critical component in the adoption of hydrogen power. Hydrogen needs to be compressed into the available space to store enough to meet machine duty cycle requirements. 

Cummins’ joint venture with Nproxx, a world leader in high pressure hydrogen storage for both stationary and mobile applications, will be supporting OEMs and their product integration process. The storage tanks on show will have up to 700bar pressure capability to maximise capacity and operating range.
