Engine Selection Guide
Two-stroke MC/MC-C Engines
This book describes the general technical features of the MC Programme
This Engine Selection Guide is intended as a 'tool' for assistance in the initialstages of a project.
As differences may appear in the individual suppliers’ extent of delivery, pleasecontact the relevant engine supplier for a confirmation of the actual execution andextent of delivery.
For further informatoin see the Project Guide for the relevant engine type.
This Engine Selection Guide and most of the Project Guides are available on a CDROM.
The data and other information given is subject to change without notice.

Engine Data
Engine Power
The table contains data regarding the engine power,speed and specific fuel oil consumption of the en-gines of the MC Programme.
Engine power is specified in both BHP and kW, inrounded figures, for each cylinder number and lay-out points L1, L2, L3 and L4:
L1 designates nominal maximum continuous rating(nominal MCR), at 100% engine power and 100%engine speed.
L2, L3 and L4 designate layout points at the otherthree corners of the layout area, chosen for easy ref-erence.
Overload corresponds to 110% of the power atMCR, and may be permitted for a limited period ofone hour every 12 hours.
The engine power figures given in the tables remainvalid up to tropical conditions at sea level, ie.:
Blower inlet temperature . . . . . . . . . . . . . . . . 45 °CBlower inlet pressure . . . . . . . . . . . . . . . 1000 mbarSeawater temperature . . . . . . . . . . . . . . . . . . 32 °C
Specific fuel oil consumption (SFOC)
Specific fuel oil consumption values refer to brakepower, and the following reference conditions:
ISO 3046/1-1986:Blower inlet temperature . . . . . . . . . . . . . . . . 25 °CBlower inlet pressure . . . . . . . . . . . . . . . 1000 mbarCharge air coolant temperature. . . . . . . . . . . 25 °CFuel oil lower calorific value . . . . . . . . 42,700 kJ/kg
(10,200 kcal/kg)
Although the engine will develop the power speci-fied up to tropical ambient conditions, the specificfuel oil consumption varies with ambient conditionsand fuel oil lower calorific value. For calculation ofthese changes, see section 2.
SFOC guarantee
The figures given in this project guide represent thevalues obtained when the engine and turbochargerare matched with a view to obtaining the lowestpossible SFOC values and fulfilling the IMO NOxemission limitations.
The Specific Fuel Oil Consumption (SFOC) is guar-anteed for one engine load (power-speed combina-tion), this being the one in which the engine is opti-mised.
The guarantee is given with a margin of 5%.
As SFOC and NOx are interrelated parameters, anengine offered without fulfilling the IMO NOx limita-tions is subject to a tolerance of only 3% of theSFOC.
Lubricating oil data
The cylinder oil consumption figures stated in thetables are valid under normal conditions.During running-in periods and under special condi-tions, feed rates of up to 1.5 times the stated valuesshould be used.
