MAN B&W two-stroke propulsion engines

MAN Energy Solutions Tier II and Tier III engine programme The two-stroke engines in this programme are either: – Tier II engines complying with IMO Tier II – Tier III engines complying with Tier II when operated in Tier II mode, and with Tier III when operated in Tier III mode The latest updates on engine development and options are available at: www.man-es.com → marine → planning-tools-and-downloads → market-update-notes The latest updated engine programme is available at: www.man-es.com → marine → planning-tools-and-downloads → marine-engine-programme Engine type designation To ensure...

ME-B engines ME-B engines use electronically controlled pressure boosters for the fuel injection whereas actuation of the exhaust valves is camshaft operated, but with electronically controlled variable closing timing. CEAS, TCS and Engine selection guide CEAS (computerized engine application system), TCS (turbocharger selection) and Engine selection guide applications cover all engine variants including available dual fuel and Tier III technology options. These applications provide essential data for the design and dimensioning of a ship’s engine room (CEAS), applicable turbochargers (TCS)...

Specific fuel oil consumption (SFOC) The figures in the two-stroke chapter represent the values obtained when the engine and turbocharger are matched to the lowest possible SFOC values while fulfilling the IMO NO X Tier II or Tier III emission limits. The SFOC figures are given in g/kWh and are based on the use of a fuel oil with a lower calorific value (LCV) equal to 42,700 kJ/kg at ISO conditions: – turbocharger inlet air temperature 25°C – turbocharger inlet air pressure 1,000 mbar – cooling water temperature 25°C Tolerances The energy efficiency design index (EEDI) has led to increased...

There are exceptions to this rule, S40ME-C9.5 and S35ME-C9.7 are also available as standard high-efficiency applications offering all Tier II standard tunings and all Tier III options requiring a high-efficiency turbocharger. Only engine specifications for which an applicable high-efficiency turbocharger is available are subject to firm order. Fuel consumption and optimisation possibilities for Tier II engines Various optimisation possibilities for improved part-load and low-load SFOC are available for MAN B&W type engines. High-load optimisation is for best possible SFOC at 100% engine...

ME-GI, ME-LGI and ME-GA dual fuel engines This engine programme includes a number of engines designed for gas fuel (ME-GI and ME-GA engines) and liquid gas fuel (ME-LGI engines) operation. ME-GA The ME-GA engine is the latest addition to our dual fuel portfolio. Methane is admitted during the compression stroke in the Otto cycle process, which allows for a lower supply pressure compared to ME-GI engines. This is especially interesting for LNG carrier designs where boil-off gas handling and engine fuel gas supply is integrated. The ME-GA engine includes EGR. This enables Tier III compliance...

G95/90/80/70ME-C10.5-GI engines have a gas tuning, called “dual fuel gas optimised”, with improved gas consumption in dual fuel mode. All other ME-GI engines have a “dual fuel standard” gas tuning. Both gas tunings apply to both Tier II and all Tier III technologies. The following fuel consumption figures are shown in the tables for dual fuel engines: – dual fuel mode with distribution of specific gas consumption (SGC) and specific pilot oil consumption (SPOC) – fuel oil mode Guarantee figures for dual fuel engines are given for heat rate, which has the same tolerances as SFOC guarantees,...

Tier III technologies To ensure compliance with IMO Tier III regulations, a Tier III NO X reduction technology must be selected. The preferred technology depends on market demands, engine type, other requirements, and operational pattern. The Emission Project Guide provides more detailed descriptions of these technologies at: www.man-es.com → marine → planning-tools-and-downloads → project-guides → two-stroke All Tier III engines have at least two operating modes: – Tier III mode fulfilling the IMO Tier III regulations – Tier II mode fulfilling the IMO Tier II regulations Tier III...

SCR Two SCR concepts are available: – H PSCR: High-pressure SCR with a reactor installed upstream the turbocharger(s) – L PSCR: Low-pressure SCR with a reactor installed downstream the turbocharger(s) SCR operation applies to most ME-C and ME-B engines, including some dual fuel engine types. The SCR system must be supplied by an approved supplier. ME-GA As mentioned on page 10, the ME-GA engine is Tier III compliant in dual fuel mode, and as it is equipped with EGR as standard, it is also Tier III compliant in fuel oil mode. Application of high-sulphur fuels and SO X scrubbers All...

Some dual fuel engines are available on request with high-sulphur fuels in Tier II fuel oil mode with a scrubber installed. The fuel specification must be selected at engine order as it impacts the engine design. Fuels with a viscosity below 700 cSt at 50°C can be used. Waste heat recovery systems Waste heat recovery systems (WHRS) are available for certain engine configurations on request for both Tier II and Tier III engines with high-efficiency turbochargers. Contact MAN Energy Solutions for further information. Power take off systems Power take off (PTO) systems are available on request...
