4.1 Oil supply
4.1.1 Introduction
In all operating states, a functioning and carefully executed oil supply is an important pre-
requisite for trouble-free operation of the turbocharger.
The lubrication of the turbocharger is usually carried out with oil from the engine oil circula-
tion.
u Comply with the enginebuilder's specifications regarding the selection of lubricating oil
and the oil change intervals.
For more information on the oil supply, refer to Chapter Oil pressure, oil temperature →34.
4.1.2 Oil filtering
Filtering of the lubricating oil with a filter mesh width of ≤0.050mm is sufficient for the tur-
bocharger.
4.1.3 Oil pressure
Comply precisely with the oil pressure before the turbocharger for trouble-free operation.
If the oil pressure at the inlet of the turbocharger is too high, it can be reduced with a
throttle valve. The throttle valve is normally already fitted on the turbocharger and has been
correctly set by the enginebuilder. This takes place either during the trial run on the engine
test bed or during the trial phase of the system.
If the oil pressure values are outside the admissible range during normal operation, you
must contact the enginebuilder.
4.2 Inspection procedures
4.2.1 Introduction
Inspection procedures include preventative visual controls, monitoring and measuring work
before and during commissioning. Inspection procedures enable changes to the turbochar-
ger to be detected. Machine damage can be prevented.
