Lubrication System Schematic Layout :
Description :
The lubrication system layout is as shown in the
schematic above. The oil pump is mounted on the
crankshaft pulley side. 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 nozzle to the
underside of the piston to cool it.
One more path takes the oil up from the
crankshaft oil gallery to camshaft oil gallery in
cylinder head and lubricates the camshaft. The
camshaft oil gallery also provides the oil needed
by the HLA. There is separate line that goes from
the cylinder head to lubricate the turbocharger
and the return line is connected to the cylinder
block. The relieved oil drains back to oil sump.
