The use of alternative marine fuels such as methane, ethane, methanol, ethanol, LPG and DME has been highlighted as a means to comply with the exhaust gas emission regulation (MARPOL Annex VI). Recently, two kinds of 2-stroke dual-fuel marine diesel engines that use such alternative marine fuels, namely, the Mitsui-MAN B&W ME-GI engine and the Mitsui-MAN B&W ME-LGI engine, came into market. This paper explains the design features and measurement results of both Mitsui-MAN B&W ME-GI and ME-LGI engines. Lower NOx emissions have been obtained when using such alternative fuels, and with further performance optimization a reduction in fuel consumption was achieved.
