20,000 hours convinced

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%.

Our injector nozzle

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)
