Layout Diagram
The layout diagram applicable for the MC engines is defined
by the power and speed combinations L 1 - L 2 - L 3 and L 4 , with
L 1 indicating the Nominal Maximum Continuous Rating.
Any combination of speed and power within the layout dia-
gram may be used for selecting the Specified MCR and the
Optimising point.
The optimising point ”O” has to be the specified MCR ”M” for
the types: S46MC-C, S42MC, L42MC, S35MC, L35MC and
S26MC.
If the compact engines: S70MC-C, S60MC-C and S50MC-C
are without VIT fuel pumps they also have to be optimised at
the specified MCR power ”O” = ”M”.
The power is stated in kW and in metric horsepower
(1 BHP = 75 kpm/s).

Load Diagram
The load diagram defines the power and speed limits for
continuous as well as overload operation of an installed en-
gine having an optimising point ”O” and a specified MCR
point ”M” that confirm the ship’s specification.

Point ”A” is a 100% speed and power reference point of the
load diagram, and is defined as the point on the propeller
curve (line 1) through the optimising point ”O”, having the
specified MCR power.
The service points of the installed engine incorporate the en-
gine power required for ship propulsion and shaft gene-rator,
if installed.
Limits for continuous operation
The continuous service range is limited by lines 4, 5, 7
and 3.
Limits for overload operation
The area between lines 4, 5, 7 and the heavy dashed line 8
is available for overload running for limited periods only
(1 hour per 12 hours).
Emission Control
All MC engines in this folder comply with the IMO speed de-
pendent NO x emission limitations, measured according to the
ISO 8178 test cycles E2/E3 for Heavy Duty Diesel Engines.
Specific Fuel Oil Consumption (SFOC)
The figures given in this folder represent the values obtained
when the engine and turbocharger are matched with a view
to obtaining the lowest possible SFOC values and fulfilling
the IMO NO x emission limitations.
The SFOC figures are given with a tolerance of 5% and are
based on the use of a fuel with a lower calorific value of
42,700 kJ/kg (10,200 kcal/kg) at ISO conditions:
1,000 mbar ambient air pressure
25 °C ambient air temperature
25 °C cooling water temperature
SFOC and NO x are interrelated parameters, so an engine of-
fered without fulfilling the IMO NO x limitations is subject to a
tolerance of only 3% of the SFOC.
