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 low-pressure and high-pressure stage.
The low-pressure and high-pressure stage are usually lubricated with oil from the engine oil
circulation.
The directives of the enginebuilder on the selection of the lubricating oil and the oil
u
change intervals must be followed.
4.1.2 Pre-lubrication
Before the engine is started, the plain bearings of the low-pressure and high-pressure stage
must be pre-lubricated. You can do this by using an electrically driven oil pump.
Switch on the oil pump.
u
Build up oil pressure.
u
Do not exceed a pre-lubrication time of 2 minutes.
u
Start the engine.
u
Let the oil pump run until the pump driven by the engine generates sufficient pressure.
u
Turbo Systems recommends integrating the entire pre-lubrication cycle into the engine con-
trol.
4.1.3 Oil filtering
Lubricating oil filtering with a filter mesh width of ≤ 0.034 mm is sufficient for these low-
pressure and high-pressure stages.
4.1.4 Oil pressure
Comply precisely with the oil pressure before the low-pressure and high-pressure stage for
trouble-free operation.
The admissible values are specified in chapter
4.1.5 Oil orifice in the high-pressure stage
With an oil inlet pressure of more than 3 bar (when engine under load) before the high-pres-
sure stage, the bearing casings are equipped as standard with an orifice at the oil inlet.
