Direct injection spark-ignition engines are becoming increasingly important, and their potential is still to be fully exploited. Increased power and torque coupled with further reductions in fuel consumption and emissions will be the clear trend for future developments. From today's perspective, the key technologies driving this development will be new fuel injection and combustion processes. The book presents the latest developments, illustrates and evaluates engine concepts such as downsizing and describes the requirements that have to be met by materials and operating fluids. The outlook at the end of the book discusses whether future spark-ignition engines will achieve the same level as diesel engines.

Over the last several years, there has been much discussion on the interrelation of CO2 emissions with the global warming phenomenon. This in turn has increased pressure to develop and produce more fuel efficient engines and vehicles. This is the central topic of this book. It covers the underlying processes which cause pollutant emissions and the possibilities of reducing them, as well as the fuel consumption of gasoline and diesel engines, including direct injection diesel engines. As well as the engine-related causes of pollution, which is found in the raw exhaust, there is also a description of systems and methods for exhaust post treatment. The significant influence of fuels and lubricants (both conventional and alternative fuels) on emission behavior is also covered. In addition to the conventional gasoline and diesel engines, lean-burn and direct injection gasoline engines and two-stroke gasoline and diesel engines are included. The potential for reducing fuel consumption and pollution is described as well as the related reduction of CO2 emissions. Finally, a detailed summary of the most important laws and regulations pertaining to pollutant emissions and consumption limits is presented. This book is intended for practising engineers involved in research and applied sciences as well as for interested engineering students.

Das Buch behandelt die Entstehung von Schadstoffemissionen und die Moeglichkeiten zu deren Verringerung sowie den Kraftstoffverbrauch bei Otto- und Dieselmotoren einschliesslich Dieselmotoren mit Direkteinspritzung. Neben den motorischen Aspekten der Schadstoffbildung und Schadstoffminderung werden Systeme und Verfahren zur Abgasnachbehandlung dargestellt. Die wichtigsten Einflusse der Kraft- und Schmierstoffe (sowohl konventionelle als auch alternative Kraftstoffe) auf das Schadstoffverhalten werden beschrieben. Neben konventionellen Otto- und Dieselmotoren werden auch Magermotoren und Ottomotoren mit Direkteinspritzung sowie Zweitakt-Otto- und Dieselmotoren behandelt. Auch das Potential der Moeglichkeiten im Hinblick auf Verbrauchsabsenkung und Minimierung der Schadstoffemissionen wird dargestellt, ebenso die damit verbundene Verringerung der CO2-Emission. Am Ende des Buches sind die wichtigsten Gesetze und Verordnungen uber Emissions- und Verbrauchsgrenzwerte in einer ausfuhrlichen UEbersicht zusammengestellt.

Dieses Werk enthält auf über 1200 Seiten umfassende Informationen über Otto- und Dieselmotoren. In wissenschaftlich anschaulicher und gleichzeitig praxisrelevanter Form sind die Grundlagen, Komponenten, Systeme und Perspektiven dargestellt. Über 140 Autoren aus Theorie und Praxis haben dieses Wissen erarbeitet. Damit haben sowohl Theoretiker als auch Praktiker die Möglichkeit, sich in kompakter Form ausführlich über den neuesten Stand der Motorentechnik zu informieren. Neue Entwicklungen zur Hybridtechnik und alternativen Antrieben wurden aktualisiert. Das Literaturverzeichnis wurde auf über 1400 Stellen erweitert.
