High power combined with high efficiency: Our two-stroke engines

MAN B&W ME-C

More compact than others, our ME-C engines with electronic controls serve up a host of advantages. You can look forward to superior performance parameters, fully integrated electronic control as well as the necessary fuel injection pressure and rate shaping at any load. Plus the ME-C engine can be retrofitted for alternative fuels such as methanol, LPG, LNG or ethane.

  • Engine speed: 58 – 167 rpm
  • Output: 4,350 – 82,440 kW at L1
 

MAN B&W ME-GI

The ME-GI engine impresses with low operating costs and the highest thermal efficiency on the market. Because of its negligible methane slip, low GHG, and reduced CO2 emissions, it is the most environmentally friendly technology available. By the optional use of fuel oil or LNG, it represents a highly efficient, flexible, propulsion-plant solution.

  • Engine speed: 58 – 167 rpm
  • Output: 4,350 – 82,440 kW at L1

MAN B&W ME-GIE

The technology of the ME-GIE is based on our successful ME-GI engine. This engine can be operated with ethane as well as LNG – which makes it a good choice and especially lucrative for Ethane carriers. This engine offers very competitive fuel oil and gas consumption, plus operational stability and efficiency due to the diesel principle. 

  • Engine speed: 62 – 127 rpm
  • Output: 8,300 – 29,120 kW at L1

MAN B&W ME-GA

The ME-GA engine is the latest addition to our dual fuel portfolio. Methane is admitted during the compression stroke, which allows for a lower supply pressure compared to other dual fuel engines. This is especially advantageous for vessels with large amounts of boil-off gas, like LNG carriers. The ME-GA engine is Tier III compliant in gas mode, and offers minimal installation and operating costs.   

  • Engine speed: 66 – 78 rpm
  • Output: 14,150 – 16,980 kW at L1

MAN B&W ME-LGIM

Our ME-LGIM is a dual fuel engine which is characterized by its high efficiency. One of the advantages: It runs on methanol – the cost-effective and innovative marine fuel of today and tomorrow. Why? It’s biodegradable and burns clean, it is reasonable to modify storage and infrastructure, and it significantly reduces SOx, NOx, CO2 and particulate matter.

  • Engine speed: 79 – 117 rpm
  • Output: 8,600 – 16,020 kW at L1

MAN B&W ME-LGIP

Our ME-LGIP is the only dual-fuel engine on the market that lets you switch between HFO, MGO and LPG fuels without any loss of power or efficiency. It also ensures long-term reliability - with very minimal maintenance requirements. The low operational costs as well as the simple retrofit solution are particularly convincing.

  • Engine speed: 62 - 167 rpm
  • Output: 4,350 – 29,120 kW at L1

Always an optimal choice

The MAN Energy Solutions two-stroke portfolio delivers the highest performance and efficiency across all engine types.

MAN B&W two-stroke engines from the 30 to 95 cm bore sizes have a total power range from 3,200 kW to 82,440 measured at L1. With a vast range of different fuel injection concepts from traditional fuel oils, to gaseous and liquid gasses, MAN ensures that you have your future fuel strategy covered.

All MAN B&W engines follow the same naming convention and seemingly random engine names actually carry a lot of useful information.
