Scania DC13 XPI. Industrial engine. Operator’s manual - part 3
Starting and running
Belt transmission
When the belt transmission is new, it may make
a squeaking noise when running. This noise is
normal and disappears after 50-100 hours of op-
eration. The noise does not affect the service life
of the belt transmission.
Raised idling rotational speed for en-
gines with SCR system
If the engine is run without load for an extended
period of time, the SCR system needs to be heat-
ed by raising the idling speed. The function is
called periodic hydrocarbon evaporation and is
used to avoid damaging the SCR catalytic con-
verter.
Periodic hydrocarbon evaporation functions dif-
ferently depending on how the engine is
equipped. A warning is output for all engines if
the engine needs to be warmed up. The warning
is output after approx. eight hours if the engine is
idling without load and the outdoor temperature
is 20°C (68°F). The time is reduced as the out-
door temperature becomes colder.
For some engines, a request for automatic raising
of the idling speed is also output after the warn-
ing. If the request is confirmed, the idling speed
is raised automatically. The function is active for
45 minutes or less and is deactivated automati-
cally. If the request is not confirmed, the engine
is switched off after approx. 45 minutes, if the
engine has been configured with engine shut-
down.
Note:
With hydrocarbon evaporation, the engine speed
can rise to 1,500 rpm for all-speed engines and
with engines configured for single-speed, all hy-
drocarbon evaporation occurs at the selected ro-
tational speed.

Starting and running
Engine shutdown
IMPORTANT!
There is risk of post boiling and of damage to the
turbocharger if the engine is switched off with-
out cooling. The power must not be switched off
before the engine has stopped.
If the engine is equipped with a battery master
switch and an SCR system, the SCR system must
run for a while after the engine has been switched
off to allow it to cool down. During this period
the power must not be cut using the battery mas-
ter switch.
Note:
The battery voltage must remain on for a few
seconds after the 15 voltage is switched off so
that the control units can store the values and
switch to standby mode.
10 prohibited engine shutdowns will cause a
torque reduction (70% of fuel quantity). Reset
the engine by switching it off correctly once.
1. Run the engine without a load for a few min-
utes if it has been run continuously with a
heavy load.
2. Switch off the engine.

Checks after running
WARNING!
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
There is always a risk of sustaining burns when
an engine is hot. Particularly hot parts are engine
manifolds, turbochargers, oil sumps, as well as
hot coolant and oil in pipes and hoses.
IMPORTANT!
Check the coolant level following the first start.
Top up with coolant as necessary.
1. Check that the power supply has been cut.
2. Top up the fuel tank. Make sure that the filler
cap and the area round the filler opening are
clean to avoid contamination of the fuel.
3. If the engine is equipped with an SCR sys-
tem: Top up the reductant tank. Make sure
that the filler cap and the area round the filler
opening are clean to avoid contamination of
the reductant.
4. If there is a risk of freezing, the cooling sys-
tem must contain enough glycol. See the sec-
tion Risk of freezing.
5. If the temperature is below 0°C (32°F): Pre-
pare for the next start by connecting the en-
gine heater (if fitted).

Filled engine oil grade label
When changing oil it is important to use the cor-
rect engine oil grade. The oil filler cap must be
clearly marked with a label showing the filled oil
grade. However, there are only labels for oils
from Scania and oil grade ACEA E9.
Stick on a new label if the oil type or oil grade is
changed in favour of any of the oil types above.
Replace the label if it is missing.
If the oil grades below are used, it is possible to
order labels for the oil filler cap from Scania.

Oil analysis
To be able to extend the oil change intervals us-
ing an oil analysis, Scania LDF-4 oils must be
used. Certain laboratories offer engine oil analy-
sis.
The following conditions must remain fulfilled
when the oil is changed:
• Viscosity at 100°C (212°F): max. ±20% of
original value of the fresh oil.
• TBN (in accordance with ASTM D4739):
>3.5.
• TBN (in accordance with ASTM D4739): >
TAN (in accordance with ASTM D664).
• Oil oxidation (in accordance with
DIN 51453) > 10.
Such analysis measures the oil's TBN (Total
Base Number), TAN (Total Acid Number), fuel
dilution, water content, viscosity and the quanti-
ty of particles in the oil.
The result of a series of analyses is used as the
basis for establishing a suitable oil change inter-
val.
If the conditions are changed, a new oil analysis
programme must be carried out to establish new
oil change intervals. Work out the new oil
change interval for the engine in conjunction
with the workshop.
Note:
Only Scania LDF-4 oils may be used in conjunc-
tion with oil analysis and a possible extended oil
change interval.
Depending on the market, the warranty condi-
tions may also change if the oil change intervals
differ from the recommended Scania timetable.

WARNING!
The oil may be hot. Carefully remove the cover
from the centrifugal oil cleaner.
Use eye protection and protective gloves when
working on the centrifugal oil cleaner.
When the centrifugal oil cleaner is cleaned, there
should be some dirt deposits on the paper in the
rotor cover. If the paper is clean, the equipment
is not working as it should. If this is the case, in-
vestigate the cause of this.
Renew the paper more frequently if the dirt de-
posits are thicker than 28 mm (1.1 inches) during
a scheduled oil change.
1. Clean the cover.
2. Unscrew the nut securing the outer cover.
3. Let the oil run out from the rotor.
