Liebherr Low-Pressure Direct Injection Hydrogen Injectors for Heavy-Duty Engines

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
