Dual Fuel (DF) EnginesThe dual fuel engines from MAN Diesel & Turbo efficiently run on liquid fuels or natural gas with emissions far below the world bank limit. The possibility to switch over immediately from gas to diesel operation and vice versa provides full flexibility at multiple applications. The optimised combustion chamber gives very low fuel consumption in both operational modes.

Gas Engines (G)The 51/60G gas engine is derived from the 51/60DF engine by optimisa-tion for pure gas operation. Featuring a lower heat rate compared to the 51/60DF engine, the 51/60G is most suitable for large gas power plants.

Engine Programme with Conventional Injection SystemThese well established engine types are used in various applications all around the world. Based on long-term experience, the engines have been subject to continuous development improving their power, emissions, fuel oil consumption and reliability, making them the ‘work horse’ in your power house.

The Common Rail (CR) Engine ProgrammeMAN Diesel & Turbo well established common rail injection system permits independent and separate control of injection pressure and timing. The result is improved combustion and lower emissions with the same or even better fuel economy. This gives strong advantages, especially in the critical low load range where it becomes possible to get the exhaust gas opacity down far below the visible limit.

Full Fuel FlexibilityMAN Diesel four stroke diesel engines are designed to provide the opti-mum in fuel flexibility. The engines are the ideal source of power whether you want to build a ‘green power plant’ burning liquid biofuels or you need power from crude oil for oil production. To check the possibility of using these fuels, please contact MAN Diesel & Turbo for further information.

Engine PowerThe engine shaft power is stated in kW. For conversion between kW and metric horsepower, please note that 1bhp = 75 kpm/s = 0.7355 kW. Ratings are given according to ISO 3046-1:2002.Figures for gas engines refer to natural gas with a methane number higher than 80. Electrical power quoted is based on a normal alternator efficiency in the corresponding power range and a power factor of 0.8. Maximum output varies according to the site conditions.

Peak LoadPeak load applications are defined as Stationary plants only used a few hours a day to compensate peak demands of electrical power.

Emission ControlAll medium speed four-stroke engines in this booklet comply with the World Bank 1998 & 2007/2008 guidelines for thermal power plants < 300 MWth. All small bore four-stroke engines comply with the latest World Bank guidelines. Engines with even lower NOx values are available on request. MAN Diesel & Turbo is prepared to deliver NOx as well as SOx and particle reduction systems.

Gaseous FuelsOn natural gas, our dual fuel and gas engines comply with the World Bank 2007/2008 levels. Engines with even lower NOx values are available on request.

Heat Rate The stated heat rates refer to the following ISO reference conditions. The mechanical heat rate is based on shaft power, the electrical heat rate on output at alternator terminals:

Ambient air pressure 100 kPa Ambient air temperature 298 K (25°C) Cooling water temperature

upstream of charge air cooler 298 K (25°C) Relative humidity 30%

MAN Medium Speed EnginesThe figures are given with a tolerance of +5% and without engine driven pumps. Attached pumps will require additional fuel. The heat rate for DF engines in gas operation includes pilot fuel. Consumption figures may vary according to the alternator make and the site conditions.

For conversion between heat rate and specific fuel oil consumption (SFOC) please note that:

(g/kWh) = Heat Rate x 1,000 ______________ LHV

Specific Lube Oil Consumption (SLOC)The specific lube oil consumption is specified with a tolerance of 20%.

Masses and DimensionsThe masses stated correspond to the complete unit (including alternator). The total weight varies depending on the alternator make. All given masses are without lube oil and cooling water. Dimensions and weights are given for guidance only and are subject to change without notice. The length of the GenSet unit depends on the alternator make.
