Main targets for modern marine engines are efficiency, durability, engine size, fuel flexibility and a suitable design for the world wide production by international licensees. Significantly reduced emissions have and will set further challenges for the engine development, considering the variation of fuel quality around the world. 2010 MAN has merged the High Speed Engine activities of MAN Diesel and MAN Nutzfahrzeuge into the new Business Unit 'High-Speed Engines', using the synergies between both areas: e.g. developments based on a truck engine or test strategies and cost optimized production adapted for a marine engine with a higher cylinder numbers. Product development processes have to comply with a complexity of requirements. Precise product tender specifications based on understanding of market demands, utilization of superior materials, tools and technologies, optimal product supply chain, management of relations with suppliers, environmental and economical aspects, and short time to market. To meet all these requirements a special simultaneous development process was applied and modern tools for 3D design and data processing for R&D and production are necessary. The extensive depth of simulation in the development process allows the transfer of knowledge form one particular engine to various types. This is strongly supported by a closed 3-D-data-structure for the complete high speed engine program. To incorporate the in-house core competencies for turbo charging, injection and engine control is highly advantageous for the engine development process. The high grade of integration leads to a cost effective, compact and robust design. The outstanding simultaneous engineering process of production and engine development experts create marine engines with highest performance data.
