Did you know
- The MAN B&W ME-B engine series was introduced to the market after the ME-C engines, which themselves were introduced in 2001. The ME-B design is based on the mechanical MC-C range, which was a popular two-stroke diesel engine.
- The S70ME-B is part of the ME-B series, which features a mechanical/electronic hybrid control system where fuel injection is electronically controlled, while exhaust valve actuation is camshaft operated with electronically controlled variable closing timing. This positions it as a more advanced version than the purely mechanical MC-C engines, but less electronically controlled than the ME-C engines, where both fuel injection and exhaust valve actuation are electronically controlled.
- The S70ME-B offers optimal engine performance with electronic fuel injection control, leading to improved fuel economy, high power reliability, and better vessel maneuverability. Its design aims for a balance of power, economy, and weight savings, while also being Tier II emissions compliant.
