At bauma—the world’s main development equipment commerce honest—in Munich, Bosch positioned explicit emphasis on the potential for hydrogen engines and electrification to make the sector considerably extra sustainable.
In keeping with Bosch research, greater than half 1,000,000 development machines within the efficiency class from 56 to 560 kilowatts shall be produced internationally in 2022. With additional development predicted for this market within the coming years, the Bosch powertrain division expects to play an equally essential function in these developments.
Hydrogen engines are primarily based on established, tried-and-tested engine know-how, which is tailored to make sure a sustainable future, Bosch says. When pushed by inexperienced hydrogen, these powertrains are nearly climate-neutral.
As well as, the powertrain idea represents an efficient complement to gas cell know-how because it requires the identical automobile storage methods and an equivalent infrastructure.
Bosch says it’s engaged on hydrogen engine methods with port gas and direct injection and is already concerned in additional than 100 technical trials with clients internationally. Furthermore, the corporate has already landed its first quantity manufacturing venture in India.
Building equipment is regularly utilized in stationary, high-load purposes, and that is the precise surroundings by which hydrogen engines can shine with their excessive effectivity and robustness. However the powertrain resolution can even be used for agricultural equipment and in long-haul transport.
—Dr. Thomas Pauer, president of Bosch’s Powertrain Options division
As well as, the hydrogen engine represents a really promising possibility within the large-engine sector, for instance, as a powertrain for dump vehicles within the mining business. That is one other space by which robustness and reliability mixed with a compact design are essential to environment friendly operation.

Together with the direct injection of hydrogen, the brand new AFI-LP (different gas injector – low stress) injector from Bosch additionally permits using different fuels, resembling methanol, each for port gas and direct injection. Engine producers can thus profit from most flexibility.
eLION electrification platform. Bosch Rexroth provides an electrical powertrain resolution for cellular development equipment within the type of eLION. The product platform is designed particularly for the off-highway sector and its demanding environmental circumstances. It’s extremely scalable, extraordinarily sturdy, and provides complete purposeful security in keeping with ISO 13849.
The high-voltage eLION electrical motors (as much as 850 volts) cowl a nominal energy vary of 20 to 230 kilowatts (with peak outputs in extra of 550 kilowatts) and generate nominal torques of as much as 1,300 N·m in addition to most torques of greater than 2,500 N·m. Out there in 4 totally different sizes, they’re equally properly suited to compact and heavy-duty cellular equipment and can be utilized for each journey and work features. Preliminary pilot initiatives with clients have been underway since 2021.
Bosch can be presenting at bauma the SMG180 and SMG220 electrical motors in addition to the INVCON 3.3 inverter with its built-in DC/DC converter. These elements have been developed to be used in mild business automobiles and are additionally licensed for off-highway purposes.
