Supercharging the reciprocating piston internal combustion engine is as old as the engine itself. Early on, it was used to improve the high-altitude performance of aircraft engines and later to increase the short-term peak performance in sporty or very expensive automobiles. It took nearly 30 years until it reached economic importance in the form of the ef?ciency-improving exhaust gas turbocharging of slow- and medium-speed diesel engines. It took 30 more years until it entered high-volume automotive engine production, in the form of both mechanically driven displacement compressors and modern exhaust gas turbocharging systems. Since, in spite of promising alternative developments for mobile applications, the internal combustion engine will remain dominant for the foreseeable future, its further development is essential. Today many demands are placed on automobile engines: on the one hand, consumers insistonextremeef?ciency,andontheotherhandlawsestablishstrictstandardsfor,e.g.,noiseandexhaust gas emissions. It would be extremely dif?cult for an internal combustion engine to meet these demands without the advantages afforded by supercharging. The purpose of this book is to facilitate a better understanding of the characteristics of superchargers in respect to their physical operating principles, as well as their interaction with piston engines. This applies both to the displacementcompressorandtoexhaustgasturbochargingsystems,whichoftenareverycomplex.

Das Buch behandelt die Aufladung der Kolben-Verbrennungskraftmaschine. Dabei wird auf die Aufladegeräte und -systeme selbst, die theoretischen Zusammenhänge des Zusammenwirkens Motor und Auflade-Systeme sowie schlussendlich auf die Kriterien des Zusammenwirkens dieser System-Kombination – unter besonderer Berücksichtigung des Betriebsverhaltens – eingegangen. Es werden neue Erkenntnisse bei der Entwicklung und Adaption von Aufladesystemen, neue Darstellungsformen sowie die heute angewandten Berechnungs- und Simulationsverfahren vorgestellt, mit Beispielen erläutert und bewertet.Einen Schwerpunkt bildet das Betriebs- und Regelverhalten aufgeladener Verbrennungsmotoren in den verschiedenen Anwendungs- bzw. Einsatzgebieten.Eine Reihe ausgewählter Anwendungsbeispiele sowie ein Ausblick auf mögliche Weiterentwicklungen des Systems "Auflade-Motor" beschließen die Abhandlung.
