3 12K80MC-GI-S Chiba Power Plant The 10 Years GI Experience GI = High Pressure Gas Injection Mitsui

4 Liquid Gas Supply Station Guiding Specification for LPG, DME etc. General Data for Liquid Gas Delivery Condition: Pressure: Nominal 550 bar Max. value 600 bar Pulsation limit 3 bar Set point tolerance 5% Temperature: Approx. 25 o C -> 55 o C / tolerance 10 o C L/ /0299 4

5 From Diesel to Dual Fuel Gas Burning Combustion Process < 5 >

6 ME-GI Combustion Process Diesel Cycle Unchanged power density Unchanged load response Avoids knocking No methane slip High pressure gas Otto Cycle Power reduction or increased cylinder bore Load ramp needed Pre-mixed combustion process Methane slip 2%-4% Low pressure gas The ME-GI uses the Diesel Cycle 6

7 ME-GI Concept

8 ME-GI The Engine Parts 7S70ME-GI Fuel (& Pilot) Injector Gas Injector Gas Condition: 300 bar & 45 dgc Gas Control Block Double Wall Piping

9 ME-GI Gas Combustion Control < 9 >

10 ME-GI Leakage Control PTFE sealing rings chrome plated sealing surfaces Chrome plating Stainless steel spring PTFE sealing ring

11 ME-GI Leakage Control Gas distribution in ventilated, monitored duct No escape of gas to engine room

12 ME-GI Leakage Control Gas distribution in ventilated, monitored duct No escape of gas to engine room Ventilation System HC-sensor

13 ME-GI Design for the Research Engine

14 ME-GI Characteristics

15 ME-GI Research Engine Measurements Heat Release at 75% Load Temp. [ C] Exhaust Gas Temperatures T/C in Cyl out T/C out Engine load [%] Cylinder pressure [bara] Scav. pressure [bara] , ,0 8, , ,0 5, ,0 75 3,0 50 2,0 1,0 25 0, Engine load [%]

16 Specific NO x emission (g/kwh) ME-GI Research Engine Measurements Emissions Gas Diesel 0 NO x Engine load (%) CO CO 2

17 Gas 15% engine load < 17 >

18 Fuel Index ME-GI Gas Fuel Mode Concept Fuel oil only mode Operation profile as conventional engine Gas fuel operation mode No methane slip No knocking problems Insensitive to gas fuel Unchanged load response 100% 90% 80% 70% 60% 50% 40% % Total % Pilot Gas Fuel 30% 20% 10% 0 Pilot oil Engine Load (%SMCR) % 100

19 ME-GI Confirmed

20 IMO NOx Tier III Exhaust Gas Recirculation (EGR)

21 IMO NOx Tier III Exhaust Gas Recirculation (EGR) < 21 >

22 ME-GI and IMO NOx Tier III Exhaust Gas Recirculation (EGR) ME-GI + EGR = Tier III in Gas Mode + Tier III in Fuel Mode = Full Fuel Flexibility

23 Conclusion ME-GI and ME-LGI Over all efficiency. Operational cost Reliability Emission Emission Load response Pilot oil amount Gas operation Auto Tuning Gas Supply system Future fuels Better Better with gas price of today Unchanged Fulfilling Tier II /alt. Tier III with EGR/SCR 95% reduction on SOx Unchanged during gas operation 5% at 100% Load, reduced to 2% at 10 % load Gas operation during full load Available 6 different solutions available LNG, LPG, DME, Methanol, Ethanol

24 The ME-GI Add-on Platform Applicable for all ME Engine Types
