Did you know
- The MAN B&W ME-C series, which includes the S50ME-C, represents the electronically controlled camshaft-less low-speed diesel engines introduced by MAN Diesel (now MAN Energy Solutions) since the early 1990s, with the first commercial ME-C engine, a 7S50ME-C, appearing in February 2003. This technology built upon the experience from earlier MC-C engines, transitioning from mechanical to fully integrated electronic control for fuel injection and exhaust valve actuation.
- The S50ME-C is part of MAN B&W's two-stroke engine portfolio, positioned within the ME-C (electronically controlled, compact) series. It is a medium-bore engine, with the 'S' indicating a long-stroke design, typically favored for vessels like bulk carriers and tankers due to lower speeds. The ME-C engines are a more compact evolution of the ME-B engines, which themselves were an advancement from the mechanically controlled MC-C series.
- The S50ME-C is chosen for its superior performance parameters, compactness, and fully integrated electronic control, offering precise fuel injection pressure and rate shaping across all loads. Its electronic control system allows for improved fuel economy, lower cylinder oil consumption, better low-load operation, and enhanced emission characteristics, including reduced smoke and NOx.
