Book Description
Twentyfour years have gone by since the publication of K. Lohner and H. Muller's comprehen sive work "Gemischbildung und Verbrennung im Ottomotor" in 1967 [1.1]' Naturally, the field of mixture formation and combustion in the spark-ignition engine has wit nessed great technological advances and many new findings in the intervening years, so that the time seemed ripe for presenting a summary of recent research and developments. There fore, I gladly took up the suggestion of the editors of this series of books, Professor Dr. H. List and Professor Dr. A. Pischinger, to write a book summarizing the present state of the art. A center of activity of the Institute of Internal-Combustion Engines and Automotive Engineering at the Vienna Technical University, which I am heading, is the field of mixture formation -there fore, many new results that have been achieved in this area in collaboration with the respective industry have been included in this volume. The basic principles of combustion are discussed only to that extent which seemect necessary for an understanding of the effects of mixture formation. The focal point of this volume is the mixture formation in spark-ignition engines, covering both the theory and actual design of the mixture formation units and appropriate intake manifolds. Also, the related measurement technology is explained in this work.

Book Description
More than 120 authors from science and industry have documented this essential resource for students, practitioners, and professionals. Comprehensively covering the development of the internal combustion engine (ICE), the information presented captures expert knowledge and serves as an essential resource that illustrates the latest level of knowledge about engine development. Particular attention is paid toward the most up-to-date theory and practice addressing thermodynamic principles, engine components, fuels, and emissions. Details and data cover classification and characteristics of reciprocating engines, along with fundamentals about diesel and spark ignition internal combustion engines, including insightful perspectives about the history, components, and complexities of the present-day and future IC engines. Chapter highlights include: • Classification of reciprocating engines • Friction and Lubrication • Power, efficiency, fuel consumption • Sensors, actuators, and electronics • Cooling and emissions • Hybrid drive systems Nearly 1,800 illustrations and more than 1,300 bibliographic references provide added value to this extensive study. “Although a large number of technical books deal with certain aspects of the internal combustion engine, there has been no publication until now that covers all of the major aspects of diesel and SI engines.” Dr.-Ing. E. h. Richard van Basshuysen and Professor Dr.-Ing. Fred Schäfer, the editors, “Internal Combustion Engines Handbook: Basics, Components, Systems, and Perpsectives”

Book Description
Combustion Engines Development nowadays is based on simulation, not only of the transient reaction of vehicles or of the complete driveshaft, but also of the highly unsteady processes in the carburation process and the combustion chamber of an engine. Different physical and chemical approaches are described to show the potentials and limits of the models used for simulation.

Book Description
Due to the large number of influencing parameters and interactions, the fuel injection and therewith fuel propagation and distribution are among the most complex processes in an internal combustion engine. For this reason, injection is usually the subject to highly detailed numerical modeling, which leads to unacceptably high computing times in the 3D-CFD simulation of a full engine domain. Marlene Wentsch presents a critical analysis, optimization and extension of injection modeling in an innovative, fast response 3D-CFD tool that is exclusively dedicated to the virtual development of internal combustion engines. About the Author Marlene Wentsch works as research associate in the field of 3D-CFD simulations of injection processes at the Institute of Internal Combustion Engines and Automotive Engineering (IVK), University of Stuttgart, Germany.

Book Description
Wesentliche Unterschiede zu heutigen Brennverfahren - Potenzial des strahlgeführten Brennverfahrens bezüglich Kraftstoffverbrauch, Emissionen und Kosten - Synergien mit anderen Technologien wie variabler Ventiltrieb oder Aufladung - Herausforderungen an den Applikateur - Brennraumentwicklung - Schlüsselkomponenten Einspritzventil und Kraftstoffpumpe: Designlösungen - Zündsysteme für strahlgeführte Verbrennungssysteme. Die Benzindirekteinspritzung hat bislang keine signifikante Marktdurchdringung erlangt, da die erhofften Verbrauchseinsparungen nicht umgesetzt werden konnten und die Systemkosten noch extrem hoch liegen. Wesentliche Verbesserungen bezüglich Kosten und Nutzen kann das strahlgeführte Brennverfahren bringen, das zur Zeit in der Entwicklung steht. Der Themenband vermittelt einen Einblick in die Technologie und ermöglicht Potenzialabschätzungen zu Verbrauch, Emissionen und Kosten.

Book Description
In spite of progress in the development of alternative powertrain systems and energy sources, the internal combustion and all its derivates still are and will be the main powertrain for automobiles. In SI-engines, several approaches compete with each other like the controlled auto ignition (CAI or HCCI), throttle-free load control using variable valvetrains, stratified mixture formation with lean engine operation or highly turbo charged downsizing concepts all combined with gasoline direct injection. The presented work makes a contribution for a deeper understanding of the combustion process of a turbo charged direct injection engine operating with external EGR as well as lean stratified mixture. Using detailed test bench investigations and introducing a new optical measurement tool, the combustion process is described in detail focusing on the occurrence of non-premixed combustion phenomena. The influence of engine parameters like global and local air-/fuel ratio, external EGR and fuel rail pressure as well as the influence of fuel parameters are discussed giving a characterization of the combustion process of stratified engine operation. Furthermore, the influences of non-inert exhaust gas components on engine knock tendency are investigated using external EGR with an EGR catalyst. Opposing the results to numerical analysis, combustion characteristics of turbo charged DISI-engines are presented.
