Stuttgart, Germany- Mahle GmbH., has secured a contract with MAN Truck & Bus to supply components for the hydrogen engine of the MAN hTGX. The 16.8L, 6-cylinder engine delivers 383 kW and will feature Mahle’s hydrogen power cell unit, including pistons, piston rings, pins, and cylinder liners, alongside valve train components. MAN plans to produce 200 zero-emission trucks for select markets starting in 2025. This collaboration highlights hydrogen combustion as a vital step in commercial vehicle decarbonization, complementing Mahle’s strategy for renewable fuel-powered engines.
Dr. Roger Busch, member of the MAHLE Management Committee and Head of Sales, said, “Mahle has successfully transferred its one hundred years of expertise in engine components into the future. Our state-of-the-art pistons and other parts make the internal combustion engine fit for hydrogen and thus climate-neutral. we are able to fulfill our customers’ expectations in terms of performance, efficiency and service life.”
Mahle has succeeded in developing its engine components to meet the specific requirements of hydrogen operation. The tests at the company’s hydrogen test center in Stuttgart back up the high maturity level and already convincing suitability for series production of modern hydrogen engine technology. Thanks to the Mahle hydrogen power cell unit, in particular the oil consumption of the motor and the so-called blow-by, i.e. the leakage of hydrogen gas into the crankcase, can be reduced to a minimum. This enables a robust and failure-free operation of the motor.
Hydrogen is the renewable fuel with the greatest potential for the decarbonization of the transportation sector today. Mahle is well positioned with components and profound systems expertise for hydrogen engines as well as fuel cell powertrains in order to actively shape the climate transformation in the transportation sector.
The automotive supplier is currently working on almost 30 hydrogen engine projects for customers in the on- and off-highway sector. With the current contract from MAN Truck & Bus, another vehicle manufacturer is now going into series production using Mahle components. Further series launches with other customers are planned to follow in 2025.
