Mechanical Cylinder Lubricators
Mechanical cylinder lubricator(s), can be mounted
on the fore end of the engine, the size of which will
decide the number of lubricators needed. If driven
by the engine in sync with the crankshaft move-
ment, the lubricators could deliver timed injection
of the cylinder lubrication oil.
The lubricator(s) should have a built-in capability
for adjustment of the oil quantity and be provided
with a sight glass for each lubricating point.
The lubricators should be tted with:
• Electric heating coils
• Low ow and low level alarms.
In the ‘Engine Speed Dependent’ design, the lu-
bricator pumps a xed amount of oil to the cylin-
ders for each engine revolution.
Mainly for plants with controllable pitch propeller,
the lubricators could, alternatively, be tted with a
mechanical lubrication system which controls the
dosage in proportion to the Mean Effective Pres-
sure (MEP).
An ‘Engine Speed Dependent’ as well as a ‘MEP
Dependent’ mechanical lubricator could be
equipped with a ‘Load Change Dependent’ sys-
tem, by which the cylinder feed oil rate is auto-
matically increased during starting, manoeuvring
and, preferably, during sudden load changes, see
Fig. 9.03.02.
In that case, the signal for the ‘Load Change De-
pendent’ system comes from the electronic gov-
ernor.
