Yanmar Will Focus on Multi-Fuel Powertrain Solutions at Bauma

Booth A4.425

Focusing on its multi-fuel combustion technology, Yanmar will unveil two off-road hydrogen engine concepts at Bauma. The company’s latest e-powertrain package will also be showcased.

“Our slogan, ENERGY DIVERSITY, YOUR SOLUTION PARTNER, underlines how Yanmar can help OEMs by providing innovative, tailored solutions for the ever-changing challenges in the off-road industry. Thanks to the compatibility with HVO, we can now offer multi-fuel combustion technology in addition to our well-established products and solutions for engines using other existing fuel types. Furthermore, we will showcase innovative solutions for the electrification field.  At Bauma 2025 Yanmar will demonstrate its ability to offer the best solutions for all customers.”

said Mr Tomohisa Tao, president, Yanmar Power Technology.

Key developments in hydrogen range – concepts’ global debut at Bauma

Yanmar is growing its multi-fuel combustion technology with the development of an off-road hydrogen engine and two initial concepts will be unveiled for the first time at Bauma 2025.

Currently, electric solutions are the norm for zero-emission powertrains for off-road equipment. However, due to basic challenges such as energy density and limited charging infrastructure, Yanmar believes that a variety of zero-carbon technologies offer a greater chance of achieving carbon reductions in the future.

Hydrogen engines can share the same engine footprint as diesel, the 4TN101 Hydrogen specification, which is based on the latest diesel engine 4TN101 (displacement: 3.8 liters) has been converted to a hydrogen specification, demonstrating that it is possible to hydrogenize fuel while maintaining a high level of engine design commonality.

Yanmar already has a strong track record in hydrogen solutions, including the marine market hydrogen fuel cell commercialization in 2023-Aug, and is well on its way to developing the technology to operate hydrogen combustion engines safely and reliably in the off-road sector.

E-Powertrain Package

Yanmar will also introduce its e-powertrain package, software and R&D services.

Yanmar is an all-in-system integrator of e-powertrain solutions tailored to the various, specific needs of its OEM customers, carrying out planning, systems engineering, design validation, as well as systems evaluation, procurement, manufacturing, quality assurance and after-sales.

At Bauma there will be an actual e-powertrain integrated into a mock-up wheel loader, showcasing Yanmar’s comprehensive solution that supports all customers’ electrification strategies.

The key elements of the e-powertrain:

• At the start of the customers’ electrification concept, Yanmar proposes the most suitable specifications.
• Yanmar customizes a platform that satisfies the needs of its customers’ electrification project with the optimal use and combination of components.
• The development of e-power software that integrates all the required functions and features for a vehicle.
• The opportunity for customers to reduce development lead time and cost by using Yanmar’s proprietary platform.
• Telematics services of e-powertrain offer real-time diagnostics, troubleshooting, predictable maintenance, over-the-air updates, smart charging and many more.
