Cummins has unveiled the B6.7H hydrogen internal combustion engine (H2-ICE) showcased at Intermat 2024 in Paris. This cutting-edge technology promises to transform medium-duty and heavy-duty vehicles by offering a zero-carbon solution without compromising performance or payload capacity. The event, running from April 24th to April 27th, witnesses Cummins’ unveiling of cutting-edge technology aimed at revolutionizing the industry.
Cummins showcased a proof-of-concept medium-duty delivery truck powered by the B6.7H H2-ICE, garnering significant attention from industry experts. The engine boasts both the 15-liter and 6.7-liter capacity, delivering a robust 290 horsepower and an impressive 886 lb.-ft. of torque, ensuring a powerful and efficient performance.
One of the standout features of the B6.7H is its ability to run on zero-carbon hydrogen fuel, marking a significant step towards sustainability in transportation. With a range of 310 miles (500 kilometres) facilitated by a 700-bar pressure high-capacity hydrogen storage system, drivers can enjoy an extended driving range without harming the environment.
The new B6.7 engine 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.
