integral oil thermostat.

Auxiliary drives

The water pumps (HT, LT and Sea water) lubricat-
ing oil and fuel oil pumps are all driven from the free
end of the engine by gears housed in the pump
drive casing.

SaCoSone control system

The system undergoes testing at the factory to-
gether with the engine, ensuring minimum tuning
and functional testing during ship commissioning.

Governor

The engine employs a digital engine management
system which controls the operation of the engine
and communicates via a CAN bus link to a set of
intelligent cylinder control modules that regulate
the injector pumps and actuate the fuel injector
solenoids. The system manages injection, timing
and pressure based on a performance map.

Main bearing temperature monitoring
As an important part of the safety system the tem-
peratures of the crankshaft main bearings are
measured just underneath the bearing shells in the
bearing caps. This is carried out using oil-tight re-

1) In rare occasions it might be necessary that certain engine speed intervals have to be barred for continuous operation.
For FPP applications as well as for applications using resilient mounted engines, the admissible engine speed range has to
be confirmed (preferably at an early project phase) by a torsional vibration calculation, by a dimensioning of the resilient
mounting, and, if necessary, by an engine operational vibration calculation.

2) Engagement of clutch needs to be finished latest in 5 minutes, to minimize engine operation time without load at high
speed.

3) Dependend also on clutch in load.
4) May possibly be restricted by manufacturer of clutch. Nominal speed for activation of clutch only allowed for necessity of

switching a 2nd engine to an already driven shaft. After activation of clutch in accordance to Project Guide engine load to be
increased instantly for a homogenous load distribution between these engines.
