Accelerated load increase
Loading within the shortest period possible, depends on various factors. If higher load increases are
required than previously recommended, then in every instance these must be discussed with
Caterpillar / MaK. The time between two load increases must never be shorter than the settling time
to rated speed (entry into the steady-state band).
The maintenance intervals for cylinder heads, running gear and engine housing must be reduced
according to the duty required and its frequency.
The engine should always reach working temperature after every start, particularly in short test
runs. Running the engine for a short time only, will produce sulphurous acid which will damage the
valves and exhaust ducts in conjunction with other corrosive combustion residues.
With local control or manual monitoring of the engine, the indicators, such as pressure gauges,
thermometers and tachometers must be continually watched. The local control station should only
be left when the readings have approximately reached a steady-state condition in the desired power
range.
If there is a bad speed range owing to torsional vibration, this should be passed as rapidly as
possible. See the plate on the engine and/or A1.09.
