MTU Friedrichshafen GmbH has developed a specialized diesel engine for workboats. This new engine is a Series 4000 engine and draws on MTU's experience dating back to 1996 in the use of heavy-duty diesel engines in the construction, industrial, rail, and marine sectors. The engine is specially adapted to workboat requirements. Therefore, the key technologies focus on benefits in terms of engine performance, fuel consumption, time between overhauls, and the valid worldwide marine emissions limits such as EPA Tier 2 and EU Stage IIIA. Optimum engine design and charge air concepts were determined by means of thermodynamic and fluid dynamic analysis, as well as from information obtained in a thorough market survey. These were the basis for the final engine design and the cylinder versions: 8V, 12V and 16V. The common rail fuel injection system and combustion components were optimized in single-cylinder engine studies. These components and thermodynamic concepts were then qualified on test engines for each cylinder version. Special attention was also paid to the suitability of fuel qualities available worldwide. Another key technology, the electronic engine control system, as well as the engine operating software were also updated specifically for workboat requirements. The development process from market survey to serially produced engine and detailed information on the key technologies and engine concepts form a major part of this article about the development of Series 4000 IRONMEN workboat engines.
