The introduction of the ME engines has given rise
to the following modications:
• The camshaft has been omitted
• The mechanical type fuel pumps have been
replaced by the electronically controlled fuel
injection system
• A Hydraulic Power Supply (HPS) unit has been
introduced either mounted on the engine and en-
gine driven (EoD 440 60) or separately mounted
and electrically driven, option 4 40 660.
As a consequence, the main pipes for camshaft
lubrication and exhaust valve actuation have been
omitted.
The lubricating oil is pumped from a bottom tank,
by means of the main lubricating oil pump (4 40 60),
to the lubricating oil cooler (4 40 605), a thermo-
static valve (4 40 60) and, through a fullow lter
(4 40 65), to the engine inlet RU, Fig. 8.0.0.
RU lubricates main bearings, thrust bearing, axial
vibration damper, piston cooling, crosshead bear-
ings, crankpin bearings. It also supplies oil to the
Hydraulic Power Supply unit and to moment com-
pensator and torsional vibration damper.
Lubrication of turbochargers
Turbochargers with slide bearings are normally
lubricated from the main engine system. AB is
outlet from the turbocharger, see Figs. 8.03.0 to
8.03.04, which are shown with sensors for UMS.
Figs. 8.03.0 to 8.03.04 show the lube oil pipe ar-
rangements for different turbocharger makes.
