论文已在上海2013年CIMAC大会上发表，论文版权归CIMAC所有。 The Product Portfolio of Diesel Engines by MAN Diesel & Turbo contains several diesel engines adapted to special market segments. There are several challenges driving the actual development of diesel engines. Most important are the rules and regulations regarding emissions, the trend of global eco-nomics and the significance of new markets like off-shore exploration. Especially the diesel engines have to include new technologies in order to manage the tradeoff between emissions and specific fuel oil consumption. This paper shows diesel engines with con-sequent design for a special market segment. Some new technologies introduced into the market some years ago have passed now a reasonable operation time. Hence it is time to analyze the field issues in order to evaluate the technology readiness. The study of problems in diesel engine operation is also a method to show the need of new technologies due to the change of mixtures of heavy fuel or the like. The market specific design is shown for the 28/33D engine, which is developed for the High speed ferry market and the navy market. The 32/44K engine is an example for an optimized design for auxiliary gensets. The well-known 32/40CD is taken as an example for the need of new design adapted to new heavy fuel oil mixtures. Long term experience with Common Rail technology is available for the 32/44 CR engine type. This engine is also an example for the potential to increase output or adapt new technologies. A damage of an injection part will be used as example to show pitfalls with long term validation for optimized parts. This engine is also an example for the adaption of new technologies like variable valve timing, common rail and two stage turbo charging.
