Did you know

The MAN B&W G-type engines, including the G50ME-C, are part of the 'Green' or ultra-long stroke series, which is a later addition to the MAN B&W engine portfolio, designed to allow for the lowest engine speeds and largest propellers. The G50ME-C9.6 was introduced with optimized performance, with upgraded versions included in the Marine Engine Programme 2017.
The G50ME-C belongs to the ME-C (electronically controlled) engine series, which offers advanced electronic control of the cylinder process, including fuel injection timing and exhaust valve actuation. Within the MAN B&W two-stroke engine range, the 'G' designation signifies an ultra-long stroke, positioning it as a highly efficient option compared to 'K' (short-stroke), 'L' (long-stroke), and 'S' (super long-stroke) types.
The G50ME-C is chosen for its ultra-long stroke design, which enables lower engine speeds and the use of larger propellers, leading to improved fuel efficiency and reduced CO2 emissions. Its electronic control system allows for optimized fuel injection and exhaust valve operation, contributing to better performance across various loads and compliance with IMO Tier II and Tier III emission regulations.
