Description
Please note
▪
Only maximum continuous rating (P
MCR
(kW)) should be used in order to
evaluate the SLOC.
▪
During engine running-in the SLOC may exceed the values stated.
The following formula is used to calculate the SLOC:
In order to evaluate the correct engine SLOC, the following circumstances
must be noticed and subtracted from the engine SLOC:
A1:
▪
Desludging interval and sludge amount from the lubricating oil separator
(or automatic lubricating oil filters). The expected lubricating oil content of
the sludge amount is 30%.
The following does also have an influence on the SLOC and must be consid-
ered in the SLOC evaluation:
A2:
▪
Lubricating oil evaporation
▪
Lubricating oil leakages
▪
Lubricating oil losses at lubricating oil filter exchange
The lubricating oil density,
ρ
@ 15°C must be known in order to convert
ρ
to
the present lubricating oil temperature in the base frame. The following for-
mula is used to calculate
ρ
