This book provides an introduction to the design and mechanical development of reciprocating piston engines for vehicular applications. Beginning from the determination of required displacement and performance, coverage moves into engine configuration and architecture. Critical layout dimensions and design trade-offs are then presented for pistons, crankshafts, engine blocks, camshafts, valves, and manifolds. Coverage continues with material strength and casting process selection for the cylinder block and cylinder heads. Each major engine component and sub-system is then taken up in turn, from lubrication system, to cooling system, to intake and exhaust systems, to NVH. For this second edition latest findings and design practices are included, with the addition of over sixty new pictures and many new equations.
The powertrain is at the heart of vehicle design; the engine – whether it is a conventional, hybrid or electric design – provides the motive power, which is then managed and controlled through the transmission and final drive components. The overall powertrain system therefore defines the dynamic performance and character of the vehicle. The design of the powertrain has conventionally been tackled by analyzing each of the subsystems individually and the individual components, for example, engine, transmission and driveline have received considerable attention in textbooks over the past decades. The key theme of this book is to take a systems approach – to look at the integration of the components so that the whole powertrain system meets the demands of overall energy efficiency and good drivability. Vehicle Powertrain Systems provides a thorough description and analysis of all the powertrain components and then treats them together so that the overall performance of the vehicle can be understood and calculated. The text is well supported by practical problems and worked examples. Extensive use is made of the MATLAB(R) software and many example programmes for vehicle calculations are provided in the text. Key features: Structured approach to explaining the fundamentals of powertrain engineering Integration of powertrain components into overall vehicle design Emphasis on practical vehicle design issues Extensive use of practical problems and worked examples Provision of MATLAB(R) programmes for the reader to use in vehicle performance calculations This comprehensive and integrated analysis of vehicle powertrain engineering provides an invaluable resource for undergraduate and postgraduate automotive engineering students and is a useful reference for practicing engineers in the vehicle industry
Für die Betriebssicherheit und Lebensdauer von Verbrennungsmotoren sind ihre Lagerungen von entscheidender Bedeutung. In den letzten Jahrzehnten wurden hier wesentliche Fortschritte in der Werkstoff- und Schmierstoffentwicklung, der Lagergestaltung und der Berechnung verzeichnet. Die heute in der Großserie erreichbare Fertigungsgenauigkeit und Effektivität hat beachtliche Leistungssteigerungen und Kraftstoffeinsparungen mit sich gebracht, die nur dank der parallelen Entwicklung auf dem Gebiet der Lager- und Schmierstofftechnik möglich waren. In diesem Buch werden, ausgehend von den Aufgaben der Lagerung und den tribologischen Grundlagen, moderne Schmiersysteme von Verbrennungsmotoren behandelt, neue Konstruktions- und Berechnungsmethoden dargestellt und eine optimale Auslegung der Lagerung vorbereitet. Auf neuzeitliche Lagerwerkstoffe und Lagerherstellung wird ebenso eingegangen wie auf Schäden und Prüfeinrichtungen von Verbrennungsmotoren-Gleitlagern. Die an den weiteren Reibstellen auftretenden Probleme werden ebenfalls erläutert.
Die Getriebetechnik hat einen bedeutenden Einfluss auf so wichtige Eigenschaften wie den Verbrauch, die Fahrbarkeit, das Gewicht und die Kosten von Fahrzeugen. Zudem ist Bewegung in die Technik gekommen: Vielfältige Kombinationen aus Verbrennungsmotor, E-Motor und Getriebe sind inzwischen machbar. Die Autoren stellen in dem Band viele Komponenten und Sub-Systeme vor – für eine umfassende und zeitlose Kompetenz. Dabei geht es ihnen darum, neben dem Know-how auch das Wissen um die Notwendigkeit von Getriebetechnologien zu vermitteln.

Volume 2 of the two-volume set Advanced direct injection combustion engine technologies and development investigates diesel DI combustion engines, which despite their commercial success are facing ever more stringent emission legislation worldwide. Direct injection diesel engines are generally more efficient and cleaner than indirect injection engines and as fuel prices continue to rise DI engines are expected to gain in popularity for automotive applications. Two exclusive sections examine light-duty and heavy-duty diesel engines. Fuel injection systems and after treatment systems for DI diesel engines are discussed. The final section addresses exhaust emission control strategies, including combustion diagnostics and modelling, drawing on reputable diesel combustion system research and development. Investigates how HSDI and DI engines can meet ever more stringent emission legislation Examines technologies for both light-duty and heavy-duty diesel engines Discusses exhaust emission control strategies, combustion diagnostics and modelling
Besides financial goals, companies increasingly start formulating strategic environmental goals. However, the management and control of these goals remains a challenge. Therefore, this thesis aims to develop a method that is able to systematically integrate financial and environmental data in investment processes to support the achievement of strategic environmental and financial goals of companies. This new integrated investing method intends to provide a sufficient degree of scientific quality on the one hand and practical applicability on the other hand. In context of this thesis, a deficit analysis assesses reasons why current methods of environmental management accounting have not established as common business practice so far. During the first part of the subsequent method development a set of seven requirements is composed. On basis of these requirements additional methods of environmental management and management accounting systems are evaluated resulting in a final set of three approaches representing the basis of developing the new integrated investing method. After developing and describing the new integrated investing method, the method is applied in seven case studies within the Volkswagen Group. This method application verifies the method’s practical applicability as well as its ability to manage and control strategic environmental and financial goals. In conclusion, this dissertation contributes to the development and application of a new integrated investing method that aims to ensure a sufficient degree of scientific quality and practical applicability. With the help of this method, it is able to systematically integrate environmental impacts in investment processes of companies in order to manage and control the achievement of strategic environmental and financial goals.
