Operation at Low Load
1. General
See the data that follow:
D 0240 − 1 Usual Operation, paragraph 2 Checks and Precautions
D Trace heating of the fuel system during operation
D Temperature of the cooling medium in the usual range (see 0250 − 1 Operating
Data Sheet)
D Careful treatment of the fuel (see 0720 − 1 , Fuel Treatment and Fuel System)
D 0750 − 1 Operating Media, paragraph 3 Cylinder Lubricating Oil.
The cylinder lubricating oil quantity automatically adapts to the lower engine load. The
WECS − 9520 controls the lubricating oil quantities related to the engine load.
2. WECS − 9520 Injection Control
At low load the WECS − 9520 automatically cuts out one of the three injection valves in
each cylinder. At very low load, two of the three injection valves are cut out.
This makes sure that the engine has the best fuel mist and combustion properties,
which decreases smoke from the funnel and fuel consumption.
The WECS
− 9520 changes the cutting out of the three injection valves at regular
intervals to get an equal thermal load in the combustion chamber.
There is no time limit to operate the engine at low load.
