D. LUBRICATION SYSTEM
Lubrication System Schematic Layout
Description
The lubrication system layout is as shown in the
schematic above. The oil pump is mounted inside
the crankcase. Oil is drawn up from the sump
through oil pump strainer and passes through the
pump to the oil cooler and then to the filter.
The filtered oil flows through the internal drilled
holes into the crankshaft oil gallery from here it is
supplied to connecting rod bearings and also to the
main bearings by means of intersecting passages
drilled in the crankshaft. It is then injected through
the cooling nozzles to the underside of the piston /
piston gallery for cooling. There is a separate line
that goes to lubricate the turbocharger.
There is another path which takes the oil up from
the crankshaft oil gallery to camshafts oil gallery in
cylinder head and lubricates the camshaft. The
camshaft oil gallery also provides the oil needed by
the HLA. The relieved oil drains back to oil sump.
