MAN ES ME-LGIM

The MAN ES ME-LGIM is a two-stroke, low-speed, dual-fuel engine from MAN Energy Solutions that burns methanol by high-pressure liquid injection, with a fuel-oil pilot to ignite the charge. LGIM stands for liquid gas injection methanol, and the engine is the methanol member of the ME-LGI family alongside the LPG-burning ME-LGIP. Because methanol is injected at high pressure and burns on the diesel cycle, the engine keeps near-diesel efficiency and avoids the methane slip of LNG Otto-cycle engines. An updated pilot system lowers the pilot-oil energy fraction to about 1.5% at full load on some bore sizes. It serves container ships, product tankers, and bulk carriers, and runs Tier II with EGR or SCR for Tier III.
