Seit der ersten Auflage dieses Buches hat der Computer Einzug gehalten und die Auslegung und Konstruktion auch der Umlaufgetriebe weitgehend erleichtert. Da- bei erwies sich das damals gewahlte System der einheitlichen Bezeichnungen der Wellen als optimal, weil es die Berechnung der Betriebsdaten gegebener oder ge- suchter einfacher oder zusammengesetzter Planetengetriebe unabhangig von deren Bauart mit ein und demselben Rechenprogramm ermoeglicht. Auch die Zusammenfassung verschiedener Getriebe mit der gleichen speziellen Funktion zu einheitlich berechenbaren Typen hat sich bewahrt, denn diese koennen nun mit einheitlichen Rechenprogrammen analysiert oder ausgelegt werden. In der vorliegenden neu bearbeiteten und erweiterten zweiten deutschen Aufla- ge wurde die leichte Programmierbarkeit durch ubersichtlich dargestellte Berech- nung mit einfachen Formeln besonders beachtet. Dabei werden bei der Auslegung von Getrieben -z. B. fur variable UEbersetzungen -zuerst nur die erforderliche oder gegebenenfalls mehrere geeignete, kennzeichnenden UEbersetzungen" ermittelt und erst dann aus den vielen moeglichen, kinematisch gleichwertigen Getrieben" das konstruktiv gunstigste ausgewahlt. Die Reihe der dargestellten Varianten praktisch ausgefuhrter alterer und neue- rer Anwendungen von Planetengetrieben wurde erweitert, um die Vielfalt der An- wendungsmoeglichkeiten zu zeigen und Inspirationen fur neue Anwendungen zu fordern. Statt des Index 0 (io, 110) fur Standgetriebe werden jetzt zur sicheren Unter- scheidung der Leistungsflusse, z.B. bei Selbsthemmung, stets die Indizes 12 bzw. 21 (i12, i2lo 1112, 1121) benutzt. Dagegen konnte auf die besondere Bezeichnung m statt n fur die Drehzahlen mehrlaufiger Getriebe ohne Nachteil verzichtet werden. Die strenge Unterscheidung von Drehzahlverhaltnissen k zwangloser Getriebe von der UEbersetzung i zwanglaufiger Getriebe ist jedoch weiterhin unverzichtbar.

Die abnehmenden sachleistungsorientierten Wettbewerbsdifferenzierungen fuhren im Maschinen- und Anlagenbau zum verstarkten Ausbau produktbezogener Dienstleistungen. Zum einen werden die Sachguter durch deren steigende K- plexitat immer dienstleistungsintensiver, zum anderen werden Dienstleistungen nicht langer als add-on zum Sachgut betrachtet, sondern erobern zunehmend die fuhrende Rolle im Systemgeschaft. Es gilt somit, die Primarprodukte des Masc- nenbaus durch vor- und nachgelagerte Dienstleistungen abzusichern. Dabei taucht immer haufiger die Forderung nach sogenannten Full-Service Angeboten auf, die neben Planung, Finanzierung, Inbetriebnahme und Rucknahme auch Verfugb- keitsgarantien durch die UEbernahme der Instandhaltung und Wartung sowie den Anlagenbetrieb umfassen koennen. Diese kundenseitigen Forderungen erklaren sich aus der wirtschaftlichen Notwendigkeit, nicht wertschoepfungsrelevante P- zesse auszulagern bzw. sich auf Kernkompetenzen zu fokussieren. Daruber hinaus eroeffnet die Nutzung multimedialer Internet-Techniken die globale Erschliessung dieser Dienstleistungspotentiale. Zukunftig wird man dem Kundenwunsch entsprechen mussen, pro produzierter Einheit oder pro Produktionsstunde der Maschine abzurechnen. Dabei definiert der Kunde nur noch die Kosten, Stuckzahlen und die Qualitatsstandards der auf der Anlage zu produzierenden Guter. Die technologische Maschinenauslegung verbleibt vollstandig in der Hand des Maschinenlieferanten ohne kundenseitige Auflagen. Dieses Geschaftsmodell kann bis zu einer dynamischen Aktualisierung der Produktionseinrichtungen zur kontinuierlichen Produktivitatssteigerung r- chen.

This book will assess and compare several options for ammonia co-fueling of diesel locomotives with integrated heat recovery, multigeneration (including on-board hydrogen fuel production from ammonia), and emission reduction subsystems from energy, exergy, and environmental perspectives. Economic considerations will be presented to compare the cost of the proposed systems for different scenarios such as carbon-tax rates, diesel fuel cost and ammonia cost. Fossil fuel consumption and the associated negative environmental impact of their combustion is a significant global concern that requires effective, practical, and sustainable solutions. From a Canadian perspective, the Transportation Sector contributes more than 25% of national greenhouse gas emissions due to fossil fuel combustion, largely due to road vehicles (cars, light and heavy duty trucks). This is a complex and critical challenge to address, particularly in urban areas with high population density. There is a need to develop alternative energy solutions for mass passenger and freight transportation systems that will reduce both the traffic-volume of road vehicles as well as the emissions from the mass transportation systems. The book will be helpful to students in senior-level undergraduate and graduate level courses related to energy, thermodynamics, thermal sciences, combustion, HVAC&R, etc. The quantitative comparative assessment of such alternative energy systems provided by this book will be useful for researchers and professionals interested sustainable development.
