Usual Operation
1. General
To get the best performance, operate the engine at constant power. You must only
change the engine load and / or speed slowly, unless there are unusual conditions.
2. Checks and Precautions
During usual operation, you must do regular checks and use precautions. This lets
you operate the engine without problems. The most important of these regular checks
and precautions are given below:
D You must do regular checks of pressures and temperatures. You must obey the
limits (see 0250−1 Operating Data Sheet).
D You must compare the values of the instruments with those given in the
acceptance records and include the engine speed and power values. This gives
a good indication of engine performance. If there are differences in the values,
these must be identified.
D If there is no risk to the engine, replace instruments that are possibly defective.
Feel the pipes to compare temperatures.
1) Do a check of the values that follow:
D Fuel injection quantity
D Fuel rail pressure
D Servo oil rail pressure
D Engine speed
D Turbocharger speed
D Scavenge air pressure
D Exhaust gas temperature upstream of the turbine.
Other important data are the values of the fuel that is used each day and the lower
calorific value.
2) Do a check to make sure that all shut-off valves in the cooling and lubricating
system are in the correct position.
3) Make sure that the shut-off valves for the cooling inlets and outlets on the engine
are always fully open during operation. These shut-off valves are used only to
isolate cylinders from the cooling water system during overhauls.
If there are unusually high or low temperatures at a water outlet, the temperature
must must be gradually adjusted to the usual value. Sudden temperature changes
can cause damage (see also 2124−1 Cylinder Liner and 8017−1 Cooling Water
System).
The maximum permitted exhaust temperature at the turbine inlet must not be more
than the limit given in 0250−1 Operating Data Sheet.
4) Compare the exhaust gas temperature indications at the cylinder outlet with the
related values in the acceptance records. If larger differences between the
cylinders are shown, you must find the cause.
5) Look at the colors of the exhaust gases from the funnel. No dark smoke must
come out.
