Engine Operation

Engine Operation
Correct operation 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
minimised and engine service life can be maximised.
The time that 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 temperature. 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.
Avoid excess idling. Excessive idling causes carbon
build-up and engine slobber, these issues are
harmful to the engine.
Gauge readings should be observed and the data
should be recorded frequently while the engine is
operating. Comparing the data over time will help to
determine normal readings for each gauge.
Comparing data over time will also help detect
abnormal operating developments. Significant
changes in the readings should be investigated.
NOTICE
The engine and emissions control system shall be
operated, used, and maintained in accordance with
the instructions provided. Failure to follow the instruc-
tions could result in emissions performance that does
not meet the requirements applicable to the category
of the engine. No deliberate tampering with, or mis-
use of the engine emissions control system should
take place. Prompt action is critical to rectify any in-
correct operation, use, or maintenance of the emis-
sions control system.
Carbon Dioxide (CO
Statement
Emissions regulations require that the value of the
CO emissions be reported to the end user.

value during the EU type
For the 904D-E36TA engine, 726.73 g/kWh was
determined to be the CO
2
approval process.
The value was recorded in EU type approval
certificate. This CO measurement results from
2
testing over a fixed test cycle, under laboratory
conditions, with a(n) (parent) engine representative
of the engine type (engine family). This value shall
not imply, or express any guarantee of the
performance of a particular engine.
Engaging the Driven
Equipment
1. Operate the engine at one-half of the rated rpm,
when possible.
2. Engage the driven equipment without a load on the
equipment, when possible.
Interrupted starts put excessive stress on the drive
train. Interrupted starts also waste fuel. To get the
driven equipment in motion, engage the clutch
smoothly with no load on the equipment. This
method should produce a start that is smooth and
easy. The engine rpm should not increase and the
clutch should not slip.
3. Ensure that the ranges of the gauges are normal
when the engine is operating at one-half of the
rated rpm. Ensure that all gauges operate
properly.
4. Increase the engine rpm to the rated rpm. Always
increase the engine rpm to the rated rpm before
the load is applied.
5. Apply the load. Begin operating the engine at low
load. Check the gauges and equipment for proper
operation. After normal oil pressure is reached and
the temperature gauge begins to move, the engine
may be operated at full load. Check the gauges
and equipment frequently when the engine is
operated under load.
Extended operation at low idle or at reduced load
may cause increased oil consumption and carbon
buildup in the cylinders. This carbon buildup
results in a loss of power and/or poor
performance.
