Lubricating oil temperature at the outlet
The oil temperature at the outlet is mainly dependant on:
Lubricating oil temperature and pressure at the oil inlet
Engine load and turbocharger speed
Exhaust gas temperature
The maximum admissible oil temperature at the outlet is listed in the following table. The spec-
ified oil outlet temperature is to be considered as alarm value for the turbocharger operation
and must be monitored according to the current regulations.

If the turbocharger was operated for a longer period of time outside of the admissible range,
ABB Turbo Systems recommends to have the turbocharger inspected by an ABB Turbocharg-
ing Service Station.
4.1.1
Pre-lubrication and post-lubrication
CAUTION
Pre-lubrication
Serious damage to engine or property can result if the turbocharger is not
supplied with oil from the first moment after starting the engine.
Activate the pre-lubrication device each time before starting the engine.
The pre-lubrication time is at least 5 minutes.
The post-lubrication time is at least 10 minutes.
If the engine is operated for 5 to 10 minutes in idle mode before stopping, no additional post-
lubrication is required.
