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 – ier III engines complying with Tier II when operated in Tier II mode and T with Tier III when operated in Tier III mode The latest updates on engine development and options are available at: www. marine.man-es.com → Two-Stroke → Market Update Notes (MUN) The latest updated engine programme is available at: www.marine.man-es. com → Two-Stroke → Marine Engine Programme Engine type designation To ensure that the engine designation...

CEAS and turbocharger selection (TCS) CEAS (computerized engine application system) and TCS applications include all available Tier II and Tier III technologies and dual fuel options. These applications include all available engines and variants, and specifications can be further investigated with respect to basic data essential for the design and dimensioning of a ship’s engine room (CEAS) and applicable turbochargers (TCS). CEAS and TCS are available at: www.marine.man-es.com → Two-Stroke → CEAS Engine Calculations and → Turbocharger Selection. In CEAS and TCS, all engines in this...

Tolerances The energy efficiency design index (EEDI) has led to increased focus on part-load SFOC. Therefore, MAN Energy Solutions offers the option to select the SFOC guarantee at a load point in the range from 50% to 100%. It is recommended that the SFOC guarantee point should be limited to the range 50% to 85% for part-load or low-load tuning methods. When choosing an SFOC guarantee at or below 100%, the tolerances, adjustment and calibration at 100% will affect an engine running at the lower SFOC guarantee load point. This includes tolerances on measuring equipment, engine process...

Fuel consumption and optimisation possibilities for Tier II engines Various optimisation possibilities for improved part-load and low-load SFOC are available for the MAN B&W type engines. High-load optimisation is for best possible SFOC at 100% engine load. Optimisation of SFOC in the part-load range (50-85%) or low-load range (25-70%) requires selection of the EGB (exhaust gas bypass) tuning method or the HPT (high-pressure tuning) method available for ME-C engines. EPT (engine process tuning) is available for G95ME-C10.5, G80ME-C10.5 and G60ME-C10.5. EPT uses engine control process...

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, which allows for a lower supply pressure compared to other dual fuel engines. This is especially interesting for vessels with large amounts of boil-off gas where the investment in fuel compressors can be substantially reduced. The ME-GA engine is Tier III compliant in dual fuel mode...

Available pilot oil fraction in % For G95ME-C10.5-GI, G90ME-C10.5-GI, G80ME-C10.5-GI and G70ME-C10.5-GI a new gas tuning, called “dual fuel gas optimised”, with improved fuel consumption in dual fuel mode at the expense of a slightly increased fuel consumption in fuel oil mode has been introduced. All other ME-GI engines will have a “dual fuel standard” gas tuning without a penalty in fuel oil mode. 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...

introduce legislation on methane slip with short notice as a first measure. In order to be prepared for possible legislation on methane emissions, MAN Energy Solutions will, for the complete two-stroke engine programme, be prepared to guarantee a methane slip of 0.2 g/kWh with a tolerance of +/-0.1 g/kWh for ME-GI engines. For part-load figures of methane slip, please refer to CEAS. 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 size, other...

EcoEGR EcoEGR is an SFOC optimised version of the EGRBP system available on all ME-C engines with high-efficiency turbochargers. Compared to the standard EGRBP system, the EcoEGR engines operate with 10–15% recirculation in Tier II mode and with slightly increased recirculation in Tier III mode. For EcoEGR engines running on low-sulphur fuels (<0.5 %S), considerable overall savings are obtained. For high-sulphur fuels the overall benefits must be calculated on a case-to-case basis. EcoEGR operation is also possible for dual fuel engines, except GIE and engines with gas optimised tuning. If...
