LI2 Common rail injector
Liebherr engineers used solid materials and a flat-seat control valve in the design of the LI2 common rail injector. The resulting injector is particularly robust against aggressive fuels and thus ideally suited for demanding use in off-highway applications. The permanently leak-free injector is tuned to minimal control leakage and is thus very efficient despite low fuel consumption.
Two different nozzle diameters and different housing sizes are available for the LI2 injector. The function-related micro-precision parts are produced in-house and so the injector is custom-adapted to the needs of each customer and application.
