5 6.0 DESCRIPTION OF DIESEL GENERATING SET 6.1 DIESEL ENGINE Design and Manufacturing The diesel engine is to be built by DOOSAN Engine Co., Ltd. under license from MAN Diesel. The diesel engine will be manufactured based on the latest design received from the licensor at the date of signing of the Contract Principal Particulars of the Diesel Engine Type : In-line, four(4) stroke, direct injection, single acting, trunk piston type with exhaust turbocharger and air cooler Model : Doosan-MAN Diesel 9L21/31 Cylinder configuration : In line Number of cylinders : 9 Cylinder bore : 210 mm Stroke : 310 mm Nominal rating : 1,980 kwm Revolution : 1,000 50Hz Fuel : Heavy Fuel Oil Starting media : Max. 10 bar, Compressed air Outline Dimension & Weight of Genset Dimensions and weight of the 9L 21/31 engine(for guidance only): A : 5,379 mm B : 2,400 mm C : 7,779 mm W : H : 1,750 mm 3,289 mm Dry Mass : 31 Tons 5 / 7

6 6.1.4 Detailed Technical Specification General Turbocharged, single-acting four-stroke diesel engine of the trunk piston type with a cylinder bore of 210mm and a stroke of 310mm. The crankshaft speed is 1,000rpm Fuels The fuel system is designed to operate on the basis of the following fuel oil specifications based on ISO Diesel fuel oil The usability of DFO depends on its conformity with the key properties listed below; Density at 15 ºC : < 900 kg/m 3 Kinematic viscosity at 40 ºC : 2.0~11 mm 2 /s Pour point, winter quality : < 0 ºC Pour point, summer quality : < 6 ºC Flash point (Pensky Martens) : > 60 ºC Total sediment fraction Water content Sulphur content Ash content Coke residue (MCR) : < 0.1% wt. : < 0.3% wt. : < 2.0% wt. : < 0.01% wt. : < 0.3% wt. Cetane number or cetane index : > 35 Hydrogen sulphide Total acid number : < 2 mg/kg : < 0.5 mg KOH/g Oxidation stability : < 25 g/m 3 Lubricity (wear scar diameter) : < 520µm Cylinder Head The cylinder head is of cast iron with an integrated charge air receiver, made in one piece. It has a bore-cooled thick walled bottom. It has a central bore for the fuel injection valve and 4 valve cross flow design, with high flow coefficient. The valve pattern is turned about 20 to the axis and achieves a certain intake swirl Valves The valve spindles are made of heat-resistant material and the spindle seats are armoured with welded-on hard metal. All valve spindles are fitted with valve rotators which turn the spindles each time the valves are activated. The turning of the spindles ensures even temperature levels on the valve discs and prevents deposits on the seating surfaces. 6 / 7

7 Cylinder liner The cylinder liners, made of special centrifugal cast iron, are encased by a nodular cast iron cooling water jacket in the upper section. This is centered in the crankcase. The lower section of the cylinder liner is guided in the crankcase. The so-called top land ring fits on the top of the cylinder liner Piston The piston, which is oil-cooled and of the composite type, has a body made of nodular cast iron and a crown made of forged deformation resistant steel.it is fitted with 2 compression rings and 1 oil scraper ring in hardened ring grooves Turbocharging system The turbocharger system of the engine, which is a constant pressure system, consists of an exhaust gas receiver, a turbocharger, a charge air cooler and a charge air receiver. The turbine wheel of the turbocharger is driven by the engine exhaust gas, and the turbine wheel drives the turbocharger compressor, which is mounted on the common shaft. The compressor draws air from outside through the air filters. 6.2 GENERATOR General Manufacturer : Hyoseung Type of excitation : Brushless excitation Parallel operation : Yes Applicable standard : IEC standard Rating Time rating : Continuous Rated output : 1,881 KW / 2,350 KVA Rated voltage : 6,600 V Rated speed : 1,000 rpm Rated frequency : 50 Hz Number of phase : 3 Number of pole : 6 Power factor : 0.8 Lagging Efficiency at 0.8 pf : 95 % at full load Specifications Insulation class (all) : F Temperature rise (all) : F Cooling method : Air cooled Protection degree : IP 23 Rated Voltage regulation : ± 10% 7 / 7
