Injecting efficiency

In one of the many mines in Western Australia, Liebherr's LI3 common rail injector demonstrated its full performance potential. During the real-life test, this injector technology drove Liebherr’s 12-cylinder diesel V-engine. The D9812 installed in the Liebherr R 9400 mining excavator reached the planned end of its service life after 20,000 hours. But not the LI3 injectors installed in it. In this endurance test, they exceeded their previous service life by an impressive 25%.

Facing the challenge of achieving up to 1 megawatt in limited space? Conventional solutions rely on large 12-cylinder V-engines. Our innovative injection system empowers a compact 6-cylinder inline engine to reach 1 megawatt.

Explore the benefits:

• Compact yet powerful: Our injection system effortlessly empowers a compact 6-cylinder inline engine to reach 1 MW.
• Cost-effective: Our high-flow common cail system offers a robust, affordable alternative, significantly lowering overall costs compared to large 12-cylinders.
• Efficient and compact: Our system reduces spatial requirements without compromising performance, resulting in financial savings.
• Improve Total Cost of Ownership: By minimizing spatial demands and achieving high hydraulic efficiency, enhance your engine portfolio's impact while reducing overall costs.

The injector largely determines the combustion behavior in the engine. For example, the nozzle hole geometry and its reliable production are particularly important for the required fine atomization of the fuel. If designed correctly, the injection nozzle ensures optimal mixture formation.

Nozzle performance at a glance:

• wide range of nozzle diameters (7, 9, 13 mm)
• Selection of different spray hole geometries
• High-performance nozzle for particularly high specific cylinder performance
• High robustness and performance
• Suitable for e-fuels and synthetic fuels (from HVO to GtL)
