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 and turbocharger selection (TCS) CEAS (computerized engine application system) and TCS applications cover all engine variants including available dual fuel and Tier III technology options. These applications provide basic and essential data for the design and dimensioning of a ship’s engine room (CEAS) and for the applicable turbochargers (TCS). Useful information on...

G45ME-C9.7 available with increased speed The G45ME-C9.7 is specified with the L1 speed and power indicated below: Engine G45ME-C9.7 with increased speed* * ariant with increased speed and unchanged L1 MEP (21 bar) available on request for V 5- and 6-cylinder. Power Speed Schematic layout diagram with extended area for G45ME-C9.7. 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...

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 control and turbocharger performance. Consequently, SFOC guarantee tolerances are as follows: – 5% tolerance for 100-85% engine load – 6% tolerance for <85-65% engine load – 7% tolerance for <65-50% engine load Please note that the SFOC guarantee can only be given in one load point for Tier II engines. For Tier III engines see page 14. Turbocharging system...

EPT (engine process tuning) is available for G95ME-C10.5, G80ME-C10.5 and G60ME-C10.5. EPT uses engine control process parameters to improve part- or low-load SFOC. This engine programme introduces the G95ME-C10.6 with SEQ (sequential tuning) method. This includes sequential fuel injection and turbocharging application similar to the EGRTC Tier III technology. This will be available in the low-load version. The tuning methods mentioned are available for all SMCR points, but cannot be combined. In cases where part-load or low-load EGB tuning is applied, and a higher steam production is...

The first engines introduced are G60 and G70ME-C10.5-GA-EGRBP. Figures for these engines are included in this engine programme (see pages 92-117). Fuel Fuel designation Methane Ethane *LPG is a mixture of liquid propane and butane. In this engine programme, GI figures are included for engines where GI is applicable. Examples of figures for GIE, LGIP and LGIM are included for a selection of engines (see page 92). Pilot oil energy fraction In dual fuel mode, the pilot oil energy fraction amounts to 1.5% for GI (0.5% for G70ME-C10/9.5-GI and 5.0% for S35ME-C9.7-GI), 3.0% for GIE and LGIP, and...

All types of GI engines can operate with fuel sharing, also referred to as specified dual fuel (SDF) operation, where the ratio between pilot fuel oil and gas fuel can be selected according to preset values. Guarantee figures for dual fuel engines are given for heat rate, which has the same tolerances as SFOC guarantees, see page 10. Heat rate is defined as follows (example for methane as dual fuel): Heat rate (kJ/kWh) = SGC (g/kWh) × 50 kJ/g + SPOC (g/kWh) × 42.7 kJ/g. The CEAS report will specify the distribution between SGC and SPOC as well as the heat rate over the load range. Please...

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 technologies are designed for either low-sulphur fuels (<0.1%) or high-sulphur fuels (>0.5% and <3.5%) in Tier III operation. In Tier II operation, the engine is in all cases capable of using fuels with a high sulphur content. The fuel sulphur content must be selected when the engine is ordered, as it impacts the engine design. Fuel consumption guarantees can be given for engines for both Tier II and Tier III modes....
