2 MAN Diesel & Turbo The responsible way in leading technology MAN Diesel & Turbo is the world s leading designer and manufacturer of low and medium speed engines engines from MAN Diesel & Turbo cover an estimated 50% of the power needed for all world trade. We develop two-stroke and fourstroke engines, auxiliary engines, turbochargers and propulsion packages that are manufactured both within the MAN Diesel & Turbo Group and at our licencees. More than ever before, MAN Diesel & Turbo s development focus is the environmental performance of our engines. Using our unrivalled grasp of large engine technology, we aim to make our engines progressively cleaner, more powerful and more efficient. Our absolute commitment to reducing emissions while increasing fuel efficiency and power density starts with our active partnership in the emissions law making process and ends with the delivery of engines that achieve an ideal synthesis of prime mover characteristics. 2 32/40 Four-stroke diesel engine 32/40 Four-stroke diesel engine 3

3 Efficient, Clean and Compact NO X Reduction measures 32/40 A notable reduction in NO x, CO 2 and soot emissions is a strategical factor for success of modern diesel engines. The 32/40 combined all relevant features to significantly reduce harmful emissions. Core technologies in-house As well as its expertise in engine design, development and manufacture MAN Diesel & Turbo is also a leading manufacturer of the key technologies which determine the economic and ecological performance of a diesel engine: High-efficiency exhaust gas turbochargers Advanced electronic fuel injection equipment Electronic hardware and software for engine control, monitoring and diagnosis Our impressive array of computer-aided design tools and one of the engine industry s largest, bestequipped foundries allow us decisively to shorten product development, and application engineering processes. Our mastery of these engine technologies and, the best brains in the large engine industry are the firm foundation for Low emissions Low operating costs Low life cycle costs Long service life Committed to the future Technologies which promise compliance with the IMO Tier III emission limits valid from 2016 combined with further optimised fuel consumption and new levels of power and flexibility are already under development at MAN Diesel & Turbo. With this level of commitment MAN Diesel & Turbo customers can plan with confidence. RI Retarded Injection Retarded injection timing delays combustion heat release and thus lowers combustion chamber temperature peaks. New Piston for Increased Compression Ratio The use of a new piston provides a higher compression ratio and gives a faster reduction in temperature after the ignition of the fuel, thus reducing NO x formation. The increase in compression ratio also compensates the reduction in firing temperature due to retarded injection and hence the associated increase in SFOC. The range of technical measures employed comprises: Revised injection timing Higher compression ratios Variable Injection Timing (VIT) 4 32/40 Four-stroke diesel engine

4 Engine Specifications Modern and innovative technology The Work Horse 32/40 is in service 24 hours a day. With a power output range of 3,000 to 9,000 kw, it is ideal for small and medium sized applications. The interacting of all important parts results to low wear rates and long maintenance intervals. Marine main engines Cylinder head Engine output is limited to 100% of rated output for engines driving a propeller. Engine output is limited to 110% of rated output for engines driving a generator. Overload above 100% permitted briefly to prevent a frequency drop during sudden load application. Fuels The 32/40 engine can be operated on heavy fuel oil with a viscosity up to 700 mm²/s (cst) at 50 C. It is designed for fuel qualities up to the levels specified in CIMAC 2003 H/K700/DIN ISO Stepped piston Forged dimensionally stable steel crown (with shaker cooling) made from high grade materials and skirt in spheroidal graphite cast iron (skirt also available in steel upon request). The stepped piston and the fire ring to gether prevent bore polishing of the cylinder liner, thereby reducing operating costs by keeping lubricating oil consump tion consistently low. Chromium ceramic coating of the first piston ring with wear resistant ceramic particles in the ring surface results in minimal wear and tear, ensuring extremely long periods between maintenance. MAN Diesel & Turbo turbocharging system Industry leading designed constant pres sure turbocharging system using state-of-the-art MAN Diesel & Turbo turbochargers with long bearing overhaul intervals. High efficiency at full and part loads results in substantial air surplus and complete combustion without residues and with low thermal stresses on the combustion chamber components. The cylinder head has optimised com bustion chamber geometry for improved injection spray atomisation. This ensures balanced air-fuel mixture, reducing com bustion residue, soot forma tion and improving fuel economy. Valves Exhaust valves are designed with armoured, water cooled seats that keep valve temperatures down. Propellers on the exhaust valve shaft provide rotation by exhaust gas, resulting in the cleaning effect of the valve seat area during valve closing. Service friendly design Hydraulic tooling for tightening and loosening cylinder head nuts; clamps with quick release fasteners and/or clamp and plug connectors; generously sized access covers. Cylinder liner The precision machined cylinder liner and seperate cooling water collar rest on top of the engine frame and is there isolated from any external deformation, ensuring optimum piston performance and long service life. SaCoS one All medium-speed marine engines from MAN Diesel & Turbo are equipped with the SaCoS one safety and control system. This system undergoes a workshop test at the factory together with the engine, ensuring effortless fine tuning and functional testing during ship commissioning.
