ENGINE OPERATION
3.5 Operating Conditions
3.5.1 Winter Operation
3.5.2 High Ambient Temperatures
High Altitude
Lube Oil Viscosity
- Select the oil viscosity (SAE grade) according to the ambient
temperature when the engine is started, see 4.1.2
- Increase oil change frequency when operating below
-10°C, see 6.1.1
Diesel Fuel
- Use winter-grade diesel fuel for operation below 0°C, see 4.2.2
Additional Maintenance Work
- Drain the sludge from the fuel tank once a week. (Unscrew the
sludge drain plug).
- If necessary, allow the oil in the oil bath air cleaner and the
engine oil to settle at the ambient temperature.
- Below -20°C, after removing the starter if necessary, smear the
ring gear on the fly wheel via the pinion bore from time or time
with cold-resistant grease, (e.g. Bosch grease FT 1 V 31).
Cold-Start Aid
- At temperatures near or below freezing point, use glow plugs if
necessary, see 3.2.1. This not only lowers the starting limit
temperature, but provides easier starting at temperatures
normally not requiring a starting aid.
This not only lowers the starting limit temperature, but provides
easier starting at temperatures normally not requiring a
starting aid.
Battery
- Efficient cold starting requires a healthy battery, see 6.7.1
- The starting limit temperatures can be lowered by 4-5 °C by
heating the battery up to about +20°C. (To do so, remove the
battery and store in a warm place.)
As the altitude and ambient temperature rise, the density of air
tends to decrease, which affects the maximum power output of
the engine, the exhaust gas quality and, in extreme cases, the
starting behavior. Under transient conditions, the engine can be
used at altitudes up to 1000m and temperatures up to 30°C. If
the engine is to operate under more severe conditions (at higher
altitudes or temperatures), it will be necessary to reduce the
injected fuel quality and thus, engine power.
If you have any doubts about engine operation under these or
similar conditions, ask your engine or equipment supplier
whether the engine has been derated in the interests of reliability,
service life and exhaust gas quality (smoke). Otherwise contact
DEUTZ SERVICE.
