Two-stroke MC/MC-C Engines This book describes the general technical features of the MC Programme This is intended as a 'tool' for assistance in the initial stages of a project. As differences may appear in the individual suppliers extent of delivery, please contact the relevant engine supplier for a confirmation of the actual execution and extent of delivery. For further informatoin see the Project Guide for the relevant engine type. This and most of the Project Guides are available on a CD ROM. The data and other information given is subject to change without notice. 5th Edition February 2000
Engine Data Engine Power The table contains data regarding the engine power, speed and specific fuel oil consumption of the engines of the MC Programme. Engine power is specified in both BHP and kw, in rounded figures, for each cylinder number and layout points 1, 2, 3 and 4: 1 designates nominal maximum continuous rating (nominal MCR), at 100% engine power and 100% engine speed. 2, 3 and 4 designate layout points at the other three corners of the layout area, chosen for easy reference. Power 3 4 Speed Fig. 1.01: ayout diagram for engine power and speed Overload corresponds to 110% of the power at MCR, and may be permitted for a limited period of one hour every 12 hours. The engine power figures given in the tables remain valid up to tropical conditions at sea level, ie.: Blower inlet temperature................ 45 C Blower inlet pressure............... 1000 mbar Seawater temperature.................. 32 C 1 2 Specific fuel oil consumption (SFOC) Specific fuel oil consumption values refer to brake power, and the following reference conditions: ISO 3046/1-1986: Blower inlet temperature................ 25 C Blower inlet pressure............... 1000 mbar Charge air coolant temperature........... 25 C Fuel oil lower calorific value........ 42,700 kj/kg (10,200 kcal/kg) Although the engine will develop the power specified up to tropical ambient conditions, the specific fuel oil consumption varies with ambient conditions and fuel oil lower calorific value. For calculation of these changes, see section 2. SFOC guarantee The figures given in this project guide 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 Specific Fuel Oil Consumption (SFOC) is guaranteed for one engine load (power-speed combination), this being the one in which the engine is optimised. The guarantee is given with a margin of 5%. As SFOC and NO x are interrelated parameters, an engine offered without fulfilling the IMO NO x limitations is subject to a tolerance of only 3% of the SFOC. ubricating oil data The cylinder oil consumption figures stated in the tables are valid under normal conditions. During running-in periods and under special conditions, feed rates of up to 1.5 times the stated values should be used. 430100 400 198 22 27 1.01
