Introduction
Basic Description
The 6 cylinder mechanical engine has fuel ignited by
compression ignition (C.I.). The engine operates on
a four stroke cycle.
The engine is started by an electric starter motor. The
starter motor turns the engine via a pinion and teeth
on the engine flywheel, refer to (PIL 09-75).
When the engine runs the crankshaft drives the
camshaft via gears. The camshaft opens and closes
the inlet and exhaust valves and via push rods in time
with the four stroke cycle. The engine has 24 valves,
2 inlet and 2 exhaust valves for each cylinder.
The crankshaft also drives a mechanical fuel
injection pump via gears. The pump injects fuel via
injectors, or atomisers into each cylinder in time with
the four stroke cycle.
The pump injects fuel via injectors, or atomisers
into each cylinder in time with the four stroke cycle.
The pump is part of the mechanically actuated fuel
injection system, refer to (PIL 18-00).
Air is drawn into the engine, via the inlet manifold
and exhaust gases exit via the exhaust manifold. The
engine uses a turbocharger which pressurises the air
at the inlet manifold, refer to (PIL 18-36).
A mechanical lubrication oil pump is driven by
the crankshaft via gears. The pump pressurises
and circulates oil for engine lubrication and cooling
purposes.
A drive belt driven by the crankshaft, drives a
coolant circulation pump, alternator, radiator cooling
fan and other ancillaries such as an air conditioning
compressor.

Health and Safety
Hot Components
Touching hot surfaces can burn skin. The engine and
machine components will be hot after the unit has
been running. Allow the engine and components to
cool before servicing the unit.
Turning the Engine
Do not try to turn the engine by pulling the fan or fan
belt. This could cause injury or premature component
failure.
Notice: The engine and other components could
be damaged by high pressure washing systems.
Special precautions must be taken if the machine is
to be washed using a high pressure system.Make
sure that the alternator, starter motor and any other
electrical components are shielded and not directly
cleaned by the high pressure cleaning system. Do
not aim the water jet directly at bearings, oil seals or
the engine air induction system.
WARNING! To bleed the injectors you must turn the
engine. When the engine is turning, there are parts
rotating in the engine compartment.Before starting
this job make sure that you have no loose clothing
(cuffs, ties etc) which could get caught in rotating
parts.When the engine is turning, keep clear of
rotating parts.
Notice: Clean the engine before you start
engine maintenance. Obey the correct procedures.
Contamination of the fuel system will cause damage
and possible failure of the engine.
Notice: Do not exceed the correct level of engine
oil in the sump. If there is too much engine oil,
the excess must be drained to the correct level. An
excess of engine oil could cause the engine speed
to increase rapidly without control.
WARNING! The engine has exposed rotating parts.
Switch off the engine before working in the engine
compartment. Do not use the machine with the
engine cover open.
WARNING! Hot oil and engine components can burn
you. Make sure the engine is cool before doing
this job.Used engine crankcase lubricants contain
harmful contaminants. In laboratory tests it was
shown that used engine oils can cause skin cancer.
Notice: A drive belt that is loose can cause damage
to itself and/or other engine parts.
WARNING! Do not open the high pressure fuel
system with the engine running. Engine operation
causes high fuel pressure. High pressure fuel spray
can cause serious injury or death.
CAUTION! It is illegal to pollute drains, sewers
or the ground. Clean up all spilt fluids and/or
lubricants.Used fluids and/or lubricants, filters and
contaminated materials must be disposed of in
accordance with local regulations. Use authorised
waste disposal sites.

Operation
The Four Stroke Cycle
This section describes the cycle sequence, for the 6
cylinders of the diesel engine.
The stages in the four stroke cycle for each cylinder
are as follows:
Table 6. The Four Stroke Cycle
Stage number Piston operation Valve operation
1 The piston is at the top of its Com-
pression stroke and is about to
start its Power stroke.
Inlet and exhaust valves closed.
2 The piston is at the bottom of its
Power stroke and is about to start
its Exhaust stroke.
Inlet valves closed, exhaust valves
about to open.
3 The piston is at the bottom of its In-
duction stroke and is about to start
its Compression stroke.
Exhaust valves closed, inlet valves
about to close.
4 The piston is at the top of its Ex-
haust stroke and is about to start
its Induction stroke.
Valve operation exhaust valves
about to close, inlet valves about to
open.
Firing order
A cylinder is said to be firing, when the fuel/air mixture
ignites and the piston is about to start its power
stroke.
Four Stroke Cycle
Induction
As the piston travels down the cylinder, it draws
filtered air at atmospheric pressure and ambient
temperature through an air filter and inlet valves into
the cylinder.
Compression
When the piston reaches the bottom of its stroke the
inlet valves close. The piston then starts to rise up the
cylinder compressing the air trapped in the cylinder.
This causes the temperature and pressure of the air
to rise. Fuel is injected into the cylinder when the
piston is near to top dead centre.
Power
The piston continues to rise after the start of fuel
injection causing a further increase in pressure and
temperature.
The temperature rises to a point at which the fuel/air
mixture ignites. A cylinder is said to be firing, when
the fuel/air mixture ignites.
This combustion causes a very rapid rise in
both temperature and pressure. The high pressure
generated propels the piston downward turning the
crankshaft and producing energy.
Exhaust
Once the piston has reached the bottom of its travel,
the exhaust valves open and momentum stored
in the flywheel forces the piston up the cylinder
expelling the exhaust gases.
In a running engine these four phases are
continuously repeated. Each stroke is half a
revolution of the crankshaft, thus, in one cycle of a
four stroke engine, the crankshaft revolves twice.
