DESCRIPTION
The lubrication system layout is as shown in the
schematic above. The G-rotor oil pump is
mounted on the crankcase. Oil is drawn up from
the sump through oil pump strainer and passes
through the pump to Oil 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 flow
through the hydraulic lash adjuster (HLA).
There is another path which 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 rocker arm. Oil to chain tensioner and chain
drive through cylinder head. Oil to solenoid valve
and intake cam phaser
.
The relieved oil drains
back to oil sump.
The lubrication system consists of the following
components.
1. Oil Pump
2. Strainer
3. Oil Sump
4. Oil Filter Assembly
5. Oil Pressure Switch Sensor
6. Crankshaft
7. Piston-Connecting Rod Assy.
8. Camshaft
9. Turbocharger
10. Piston cooling nozzle
11. Vacuum Pump
12. HLA
13. RFF
14. VCT Unit
15. Solenoid Valve(OCV)
COMPONENTS
1. Oil Pump
Oil Pump is directly driven with crankshaft.
The main function of the oil pump is to circulate
oil through the engine movable components. It
sucks the oil from the oil sump through a strainer
which prevents entrance of any particles into the
pump, and supplies to the oil gallery.
To keep the oil pump from building up too much
pressure, a relief valve is also fitted to the oil
pump.

2. Oil Filter
The oil filter used is a "Spin On Type" fitted.
The main function of oil filter is to filter all
contaminants that get ingested into the engine,
along with traces of worn out metals from
