Main Engine 2-Stroke · Main Engines (2-Stroke)
The MAN 5G70ME-C9.6 is a low‑speed, five‑cylinder two‑stroke marine diesel engine delivering up to 34 350 kW at 91 rpm, notable for its hydraulic camshaft system and advanced electronic control that lower specific fuel consumption and meet IMO Tier III NOx limits.
5 = Zylinderzahl, G = Green Ultra Long Stroke, 70 = Bohrung 700 mm, ME-C = MAN Electronically controlled Mark C, 9.6 = Mark 9.6 Steuerungsgeneration.
Die G70ME-C mit 700mm Bohrung und 3256mm Hub (S/B=4.65) ist eine leistungsstarke Plattform. 5 Zylinder bei 700mm ist eher unueblich — typisch fuer spezifische Anwendungen mit moderater Leistung bei maximalem Wirkungsgrad. Grosse Containerschiffe und VLCCs nutzen normalerweise 6-8 Zylinder in dieser Bohrung.
