Oil pressure
The oil pressure in front of the turbocharger must be maintained pre-
cisely to ensure trouble-free operation.
The permissible oil pressures are specified in the following tables and
depend on the type of lubrication (engine lubrication or separate lubric-
ating system).
Engine lubrication
Kinetic viscosity 45 … 170 cST
Oil pressure [bar]
Impermissible oil pressure range ->
emergency shutdown
(without time lag)
0.0 … 0.6
Temporarily permissible (< 1h) ->
alarm
0.6 … 0.8
Permissible oil pressure range for normal opera-
tion
0.8 … 2.5
Permissible oil pressure range during engine warm-
up phase
0.8 … 4.0
Separate lubricating sys-
tem
Kinetic viscosity 12 … 170 cSt
Oil pressure [bar]
Impermissible oil pressure range ->
emergency shutdown
(without time lag)
0.0 … 0.9
Temporarily permissible (< 1h) ->
alarm
0.9 … 1.1
Permissible oil pressure range for normal opera-
tion
1.1 … 2.5
Permissible oil pressure range during engine
warm-up phase
1.1 … 4.0
NOTICE
If a
separate lubricating system
has been designed for operation in the
viscosity range of the engine lubrication system, i.e. 45 ... 170 cSt, then
the
oil pressure limits according to the engine lubrication information
may be applied for such a system.
