The low-pressure MAN B&W ME-GA engine, a 2nd generation Otto cycle engine
The MAN B&W ME-GA two-stroke dual-fuel LNG engine delivers a low CAPEX solution that is the perfect choice for certain LNG carrier designs. Based on the well-proven MAN B&W dual-fuel design with minimal installation requirements, the MAN B&W ME-GA uses an efficient ignition concept and a unique gas admission system that delivers safe and reliable operation at the lowest possible cost, while allowing an easy integration into most modern contemporary LNG carrier designs.
The engine benefits among others from a proven and cost efficient Exhaust Gas Recirculation (EGR) design for significantly lower NOx, CO2 and GHG emissions.
In addition to the advantages of using "boil-off" gas from LNG carriers, the MAN B&W ME-GA is exceptionally cost-efficient in other ways, for example with minimal installation and operational costs, simple supply and purging concepts and low maintenance costs of the fuel-gas supply system, which in combination with the cost effective and proven EGR design, put the ME-GA engine in a very strong position compared to other two-stroke low-pressure LNG engines.Well-known engine room design accommodates simple installation, and the distinctive features from the well known ME-GI platform enables you to take advantage of crews existing ME-GI know how

ME-GA - The latest dual-fuel MAN B&W two-stroke engine
The ME-GA engine design concept is the premixed Otto principle, and the efficient performance of the engine is the result of an in-house developed exhaust gas recirculation (EGR) solution. The high-pressure EGR solution has been optimised for the ME-GA engine with performance-enhancing results, which include high performance efficiency, significantly reduced methane slip, and Tier III compliance when operating on conventional fuel oils. Moreover, the development of the ME-GA engine solution, which requires only a low-pressure fuel supply, has been performed with focus on reducing capex for the LNG carrier segment. This paper introduces the unique on-engine gas admission system, and discusses the new engine optimisation achieved with the proven EGR system. The first ME-GA engine available in our engine programme is a 70-bore engine aimed at the LNG carrier segment.
