MAN B&W 2.11
Fuel Consumption at an Arbitrary Load
Once the matching point (O) of the engine has
been chosen, the specific fuel oil consumption at
an arbitrary point S , S 2 or S 3 can be estimated
based on the SFOC at point ‘ ’ and ‘2’.
These SFOC values can be calculated by using
the graphs for the relevant engine type for the
propeller curve I and for the constant speed curve
II, giving the SFOC at points and 2, respectively.
Next the SFOC for point S can be calculated as
an interpolation between the SFOC in points ‘ ’
and ‘2’, and for point S 3 as an extrapolation.

The SFOC curve through points S 2 , on the left
of point , <strong>is</strong> symmetrical about point , i.e. at
speeds lower than that of point , the SFOC will
also increase.
The above�mentioned method provides only an
approximate value. A more prec<strong>is</strong>e indication of
the expected SFOC at any load can be calculated
by using our computer program. <strong>Th<strong>is</strong></strong> <strong>is</strong> a service
which <strong>is</strong> <strong>available</strong> to our customers on request.
