Did you know
- The MAN B&W MC/MC-C engine program, from which the S70MC-C originates, has been evolving since the early 1980s. The 'C' in S70MC-C denotes a compact engine design and camshaft-controlled fuel injection and exhaust valves.
- The S70MC-C is part of MAN B&W's two-stroke engine portfolio, which encompasses bore sizes from 260 mm to 980 mm. Within the 'S' (super long stroke) series, it sits between smaller bore engines like the S60MC-C and larger ones such as the S80MC-C.
- The S70MC-C is chosen for its balance of power and efficiency, offering proven, continuously upgraded technology. It is designed to meet IMO NOx emission limitations and can be optimized for specific fuel oil consumption.
