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



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.
