Engine Operatio n
SMCS Code: 1000
Proper opera
tion and maintenance are key factors
in obtaining the maximum life and economy of
the engine. If the directions in the Operation and
Maintenance
Manual are followed, costs can be
minimized and engine service life can be maximized.
Thetimethat
is needed for the engine to reach
normal operating temperature can be less than the
time taken for a walk-around inspection of the engine.
The engine can be operated at the rated rpm after
the engine is started and after the engine reaches
operating t
emperature. The engine will reach normal
operating temperature sooner during a low engine
speed (rpm) and during a low power demand. This
procedure
is more effective than idling the engine
at no load. The engine should reach operating
temperature in a few minutes.
Gauge readings should be observed and the data
should be recorded frequently while the engine
is operat
ing. Comparing the data over time will
help to determ ine normal readings for each gauge.
Comparing data over time will also help detect
abnormal
operating developments. Significant
changes in the readings should be investigated.

Fuel Con servation Practices
SMCS Code: 1000; 1250
The efficiency o
f the engine can affect the fuel
economy. Caterpillar’s design and technology in
manufacturing provides maximum fuel efficiency in
all applicati
ons. Follow the recommended procedures
in order to attain optimum performance for the life
of the engine.
•
Avoid spilling fuel.
Fuel expands
when the fuel is warmed up. The fuel
may overflow from the fuel tank. Inspect fuel lines for
leaks. Repair the fuel lines, as needed.
•
Be aware of the properties of the different fuels.
Use only the recommended fuels.
•
Avoid unnecessary idling.
Shut off the
engine rather than idle for long periods of
time.
•
Observe the
service indicator frequently. Keep the
air cleaner elements clean.
•
Ensure that
the turbochargers are operating
correctly so that the proper air/fuel ratio is
maintained. Clean exhaust indicates proper
functionin
g.
•
Maintainagoodelectricalsystem.
One faulty battery cell will overwork the alternator.
This will consume excess power and excess fuel.
•
Ensure that the belts are properly adjusted. The
belts should be in good condition.
•
Ensure that all of the connections of the hoses are
tight. The connections should not leak.
•
Ensure that the driven equipment is in good
working order.
•
Cold engines consume excess fuel. Utilize heat
from the jacket water system and the exhaust
system, w
hen possible. Keep cooling system
components clean and keep cooling system
components in good repair. Never operate the
engine wi
thout water temperature regulators.
All of these items will help maintain operating
temperatures.
