Engine Operation - freightliner Run Smart ARGOSY Driver Manual

Cold-Weather Starting
See the engine manufacturer's operation manual for
starting aids that are approved for specific engines.
Starting After Extended Shutdown
Before engine start-up, complete the engine pretrip
inspections in Chapter
NOTICE
Failure to eliminate water-diluted lubricating oil
may lead to serious engine damage at startup.
An engine in storage for an extended period of time
(over winter, for example) may accumulate water in
the oil pan through normal condensation of moisture
on the internal surfaces of the engine. Oil diluted by
water cannot provide adequate bearing protection at
start-up. For this reason, change the engine oil and
filters after extended storage.

Engine Operation

Safety and Environmental
Considerations
WARNING
Do not operate the engine in an area where flam-
mable vapors such as gasoline or diesel fumes
are present. Shut off the engine when in an area
where flammable liquids or gases are being
handled. Failure to observe these precautions
could result in serious injury or death.
Once an engine is placed in service, the responsibil-
ity for meeting both state and local regulations is with
the owner/operator.
IMPORTANT: Depending upon local jurisdic-
tional emissions guidelines, the vehicle may not
be equipped with an emissions aftertreatment
system (ATS). Adequate maintenance of the en-
gine and the diesel particulate filter (DPF) are
the responsibility of the owner/operator, and are
essential to keep the emission levels low. Good
operating practices, regular maintenance, and
correct adjustments are factors that will help
keep emissions within the regulations.
Engine Starting, Operation, and Shutdown
23.
NOTICE
It is extremely important that the following guide-
lines be followed for engines that are equipped
with an ATS, or damage may occur to the after-
treatment device, and the warranty may be com-
promised.
•
Use ultralow-sulfur diesel with 15 ppm sul-
fur content or less.
•
Do not use fuel blended with used engine
lube oil or kerosene.
•
Use only engine lube oil with a sulfated ash
level less than 1.0 wt%.
The driver should be familiar with the vehicle warning
system in order to bring the vehicle to a safe stop if
the engine malfunctions. If the driver doesn't under-
stand how the warning system works, an engine
shutdown could occur, causing a safety hazard. See
Chapter 10 for more information.
Engine Break-In
Each engine must pass a full-load operating test on
a dynamometer before shipment, thereby eliminating
the need for a break-in. Before running the engine
for the first time, follow the instructions in the manu-
facturer's engine operation manual.
Normal Operation
WARNING
Do not operate the engine in an area where flam-
mable vapors such as gasoline or diesel fumes
are present. Shut off the engine when in an area
where flammable liquids or gases are being
handled. Failure to observe these precautions
could result in serious injury or death.
Every engine has an operating range in which it per-
forms most efficiently. The operating range extends
from maximum torque rpm at the low end, to engine
rated speed at the high end. Most engines deliver
best fuel economy when operated in the low- and
mid-speed segments of the efficiency range and pro-
duce maximum horsepower at rated speed, which is
also the recommended maximum speed of the en-
gine. For further engine-specific information, refer to
the engine manufacturer's operation manual.
