LUBRICATION
The forced feed lubrication is produced by the following components:
-
oil pump with rotors, housed in the rear part of the crankcase inside the sump.
It is driven by a helical toothed gear fitted on the crankshaft.The pump casing contains an oil pressure regulation valve.
-
water/oil heat exchanger.
-
oil filter mounting equipped with:
-
oil pressure regulation valve;
-
by-pass valve for excluding blocked oil filter;
-
cartridge oil filter.
OPERATING PRINCIPLE
The (forced type) lubrication of the engine is produced by means of an oil pump fastened to the rear part of the crankcase and
driven by the crankshaft through an intermediate gear.
This pump draws in oil from the sump and sends it to the water/oil heat exchanger, to the filter assembly and, later on, to the oil
distribution ducts in the crankcase; the pressure of the oil is controlled by the pressure valve at the filter inlet.
The oil heat exchanger is the type with flat pipes that comes into contact with the coolant.
The oil is directed, from the two oil distribution ducts, positioned lengthwise in the crankcase, to lubricate the crankshaft bearings
and the camshaft and to cool the piston through calibrated jets.
Other ducts direct the oil to each of the heads to lubricate the timing components.
The oil flow rate is managed by two pressure relief valves (4) (one per bank) which close when the oil pressure reaches minimum
values (engine idling) in order to protect the bearings and other engine components.
The components fitted in the front and rear sections of the engine are lubricated by oil sprayed by special jets .
The crankshafts for the turbines are suitably lubricated by two pipes coming from the crankcase and the drainage goes directly to
the sump.
The return oil from the various components is collected in the oil sump.
The oil is filtered by means of two cartridge filters with a paper filter element operating in series.
The opening pressure of the oil filter safety valve is 3.4
±
0.3 bar.
The theoretical starting temperature pressure for the engine lubrication pressure regulation valve (5) is around 5 bar.
The opening pressure for the piston lubrication pressure regulation valves (4) is around 2.65 bar.
