Liebherr-Components’ low-pressure direction injection (LPDI) hydrogen (H2) injectors ensure stable, precise and leak-free injection for heavy-duty engines. 

  • For H2 engines in the range of 6-16 L displacement and 200-450 kW (268.2-603.5 hp)
  • Two-valve concept ensures that H2 leakage is kept as low as possible
  • Designed for system pressures of up to 60 bar (870.2 psi)
  • Typical applications are in the range of 30 bar (435.1 psi)
  • Covers a wide range of applications
  • Allows customer-specific screw inserts to interface with the hydrogen connection
  • Geared towards most common connection types and offers flexibility in engine development
  • Blow cap also provides flexible handling
  • Easy to replace
  • Asymmetrical geometry makes an individual injection angle in the combustion chamber possible ensuring integration into different engines with sometimes widely differing installation situations
  • Flexible design supports wide range of customer-specific requirements and modular installation - including centrally, laterally and at different angles
  • Sized and designed to provide a comprehensive injection system which includes system pressure control to provide a fully integrated solution
  • Meets the transient requirements of the engine
