Fuel consumption (kg/h):
Fuel oil consumption is measured by a measuring
tank. Recommended is that a recently calibrated
electronic weight is measuring the fuel consump-
tion. Measuring time should minimum have duration
of 10 minutes. Values are stated in kg/h.
The leakage oil (kg/h) is measured over minimum 10
min and subtracted from measured fuel consump-
tion.
Leak oil
Please find below diagram for different engine types
running on MGO.
The mentioned values are measured under control-
led condition on a test bed using new fuel injection
pump / fuel injection valve, and taking into consider-
ation that temperature, viscosity, clearance, oil con-
dition, oil quality etc can differ and thereby affect the
leak oil amount.
Tolerance of the values is +/-25%.
