Liebherr developed injection systems for hydrogen (H2) combustion engines used in on- and off-highway applications. Resistance against dust, dirt, vibrations, and other harsh environmental conditions are a few of the key requirements. Peak power and dynamic load changes are among the other challenges for H2-combustion engines. Coming close to the diesel engine in terms of performance and drivability, in all applications, is one of the biggest challenges. Liebherr's system-oriented approach to hydrogen injection combines components to control pressure and flow. This enables the same driving characteristics as a diesel, while maintaining a sturdy system design. The company plans to exhibit this system during bauma 2022.
