Did you know

The MAN B&W ME-C series, which includes the S80ME-C, represents the electronically controlled evolution of MAN B&W's two-stroke diesel engines, first introduced around 2002. This series built upon decades of experience with two-stroke engine design, moving away from traditional camshaft-controlled systems to fully integrated electronic control.
The S80ME-C is part of MAN B&W's 'S' type engines, which are characterized by their longer stroke and lower speeds, traditionally favored for bulk carriers and tankers. Within the ME-C range, the '80' in its designation indicates an 80 cm (800mm) cylinder bore, placing it among the large-bore engines in the portfolio, which range from 30 to 95 cm.
The S80ME-C is chosen for its superior performance parameters, compactness, and fully integrated electronic control, which allows for precise fuel injection pressure and rate shaping at any load. This electronic control contributes to improved emission characteristics, including lower NOx emissions and smokeless operation, as well as optimized fuel consumption across various load ranges.
