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
2
) Emissions
Statement
Emissions regulations require that the value of the
CO
2
emissions be reported to the end user.
For the 904D-E28T engine,
831.2 g/kWh
was
determined to be the CO
2
value during the EU type
approval process.
For the 904D-E36TA engine,
726.73 g/kWh
was
determined to be the CO
2
value during the EU type
approval process.
The value was recorded in EU type approval
certificate. This CO
2
measurement results from
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.
