Product Description
Medium speed, four stroke, in-line version, 6, 8, 9 cylinder Diesel engines, hanging crankshaft design, turbocharged, direct fuel injection, single injection pumps., Bore: 255 mm, Stroke: 400 mm., Pin/Journal Diameter: 193/240 mm., , Alloyed quenched and tempered crankshaft materials for M25, CM25, M25C, CM25C:, UTS = 1000 N/mm (Open die forging / 6 & 8 cylinder version)., UTS = 910 N/mm (CGF - forging / 6 & 8 cylinder version)., UTS = 1050 N/mm (Open die forging / 9 cylinder version)., UTS = 960 N/mm (CGF - forging / 9 cylinder version)., , Maximum nominal alternating torsional stress for M25, CM25, M25C, CM25C:, 66 N/mm (6 & 8 cylinder version/rated speed)., 70 N/mm (9 cylinder version/rated speed)., , Alloyed quenched and tempered crankshaft materials for M25E, CM25E:, UTS = 1000 N/mm (CGF - forging / 6 & 8 cylinder version)., UTS = 1130 N/mm (CGF - forging / 9 cylinder version)., , Maximum nominal alternating torsional stress for M25E, CM25E:, 66 N/mm (6 cylinder version/rated speed)., 70 N/mm (8 cylinder version/rated speed)., 80 N/mm (9 cylinder version/rated speed)., , Engine types M25, CM25, M25C, CM25C, M25E and CM25E are optionally available with "FTC" (Flexible Cam Technology) thus to provide for variable inlet valve and injection timing to considerably reduce "low load" soot (smoke) emission by about 75% due to increased compression and temperature rating achieved by a delayed inlet valve timing and earlier injection.
