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
buildup, engine slobber, and soot loading of the
Diesel Particulate Filter (DPF). 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.
Engine Operation and the
Aftertreatment System
The exhaust gases and hydrocarbon particles from
the engine first pass through Diesel Oxidation
Catalyst (DOC). Some of the gasses and matter are
oxidized as the gasses pass through the DOC. The
gasses then pass through the Diesel Particulate Filter
(DPF). The DPF collects the soot and any ash that is
produced by the combustion in the engine. During
regeneration, the soot is converted into a gas and the
ash remains in the DPF.
The DPF may require the exhaust gas temperature to
rise to remove the soot. If necessary, the throttle
valve is operated to help in rising the exhaust
temperature.
This design of DPF will not require a service
maintenance interval. The DPF can be expected to
function properly for the useful life of the engine
(emissions durability period), as defined by
regulation, subject to prescribed maintenance
requirements being followed.
A fault code will be active for any DPF system-related
issue. Follow the troubleshooting guide to rectify the
issue.
If the DPF loses function, or is tampered with in any
way, the check engine lamp, and an amber action (if
equipped) will illuminate. A fault code will also
annunciate. The lamps and fault code will remain
active until the problem is rectified.
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 403J-E17T engine, 905.42 g/kWh was
determined to be the CO
2
value during the EU type
approval process.
For the 404J-E22T engine, 905.42 g/kWh was
determined to be the CO
2
value during the EU type
approval process.
For the 404J-E22TA engine, 799.13 g/kWh was
determined to be the CO
2
value during the EU type
approval process.
