17. LUBRICATION SYSTEM
Lubrication reduces
t d f i ti dunwanted friction, and
controls it where it is
useful. It reduces wear
on moving parts.
Clearances fill with oil so
that engine parts movethat engine parts move
or float on layers of oil
instead of directly on
h th M h leach other. Much less
power is needed to
move them and that’s a

It helps to absorb shock

Oil is also a cleaning agent.
It collects particles of metalp

them back to the sump.

19. OIL PUMP:
Oil pumps may be driven from
the camshaft or the crankshaftthe camshaft or the crankshaft.
In a rotor-type oil pump, an
inner rotor drives an outer one.
As they turn the volumeAs they turn, the volume
between them increases. This
larger volume lowers the
pressure at the pump inlet.pressure at the pump inlet.
Outside atmospheric pressure
is then higher. This forces oil
into the pump, and it fills theinto the pump, and it fills the
spaces between the rotor
lobes.

20. OIL FILTER:
The oil filter helps to
clean the oil in the
system. If the filter
clogs a valve opensclogs, a valve opens
and directs
unfiltered oil to theunfiltered oil to the
engine. Most oil-
filters on diesel
engines are larger
than those on similar

21. FUEL SYSTEM
Function of the fuel system is
to store and supply fuel to theto store and supply fuel to the
cylinder chamber where it
can be mixed with air,
vaporized, and burned tovaporized, and burned to
produce energy. The fuel,
which can be either gasoline
or diesel is stored in a fuel
tank. A fuel pump draws the
fuel from the tank through
fuel lines and delivers it
f fthrough a fuel filter to either a
carburetor or fuel injector,
then delivered to the cylinder
chamber for combustion

amounts for efficient
combustion. The
