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
engine control system (ECS) controls the lubricating oil quantities related to the
engine load.
2. ECS Injection Control
At low load the ECS automatically cuts out one of the three injection valves in each
cylinder. This makes sure that the engine has the best fuel mist and combustion
properties, thus decreasing smoke and fuel consumption.
The ECS cuts out a different injection valve 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.
