This book offers a comprehensive and timely overview of internal combustion engines for use in marine environments. It reviews the development of modern four-stroke marine engines, gas and gas-diesel engines and low-speed two-stroke crosshead engines, describing their application areas and providing readers with a useful snapshot of their technical features, e.g. their dimensions, weights, cylinder arrangements, cylinder capabilities, rotation speeds, and exhaust gas temperatures. For each marine engine, information is provided on the manufacturer, historical background, development and technical characteristics of the manufacturer's most popular models, and detailed drawings of the engine, depicting its main design features. This book offers a unique, self-contained reference guide for engineers and professionals involved in shipbuilding. At the same time, it is intended to support students at maritime academies and university students in naval architecture/marine engineering with their design projects at both master and graduate levels, thus filling an important gap in the literature.

Die Steuerung moderner Otto- und Dieselmotoren macht einen stetig steigenden Anteil an Fahrzeugelektronik erforderlich, um die hohen Forderungen nach einer Reduzierung der Emissionen zu erfullen. Um die Funktion der Fahrzeugantriebe und das Zusammenwirken der Komponenten und Systeme richtig zu verstehen, ist daher ein Fundus an Informationen von deren Grundlagen bis zur Arbeitsweise erforderlich. In diesem Heft "Abgastechnik fur Dieselmotoren" stellt Motorsteuerung lernen die zum Verstandnis erforderlichen Grundlagen bereit. Es bietet den raschen und sicheren Zugriff auf diese Informationen und erklart diese anschaulich, systematisch und anwendungsorientiert.

Das Buch behandelt die neuesten Entwicklungen in Bezug auf Ottomotoren mit Direkteinspritzung und Direkteinblasung von Kraftstoffen und Gasen, beschreibt und bewertet Motorkonzepte, wie z.B. Downsizing und Aufladung und erläutert die Anforderungen an Werkstoffe und Betriebsstoffe. Der Ausblick am Ende des Buches beleuchtet die Frage, ob Ottomotoren in Zukunft das Kraftstoff-Verbrauchsniveau von Dieselmotoren erreichen können und ob alternative Antriebe Hubkolbenmotoren verdrängen werden. Für die 4. Auflage wurden Kapitel überarbeitet und aktualisiert. Außerdem wurde ein Kapitel zur Direkteinblasung von Erdgas/Methan und Wasserstoff ergänzt. Der Ottomotor mit Direkteinspritzung und Direkteinblasung hat zunehmende Bedeutung erlangt. Dessen Potenzial ist jedoch bei weitem noch nicht ausgeschöpft. Leistungs- und Drehmomenterhöhung gepaart mit weiter reduziertem Kraftstoffverbrauch bei gleichzeitiger Schadstoffreduzierung geben klar die Richtung künftiger Entwicklungen vor. Als Schlüssel für diese Entwicklung können neue Einspritz/Einblas- und Verbrennungsverfahren gelten, die einen Technologieschub bewirken. 

Die immer weiter steigenden Anforderungen an Verbrennungsmotoren machen auch vor dessen Herzstuck - dem Kolben - nicht Halt. Fur weniger Gewicht, Reibung oder auch noch mehr Verschleissfestigkeit sind tiefe Kenntnisse uber die innermotorischen Prozesse sowie die geeigneten Werkstoffe, Konstruktions- und Bearbeitungsverfahren fur Kolben inklusive der erforderlichen Erprobungsmassnahmen notwendig. Ohne solch spezifisches Know-how kommt kein Fachmann der Kfz-Technik mehr aus, unabhangig ob er in der Konstruktion, der Entwicklung, der Erprobung oder der Instandhaltung tatig ist. Dieses Fachbuch beantwortet diese Fragen ausfuhrlich und in sehr anschaulicher und verstandlicher Weise. In dieser zweiten Auflage wurden alle Kapitel uberarbeitet und erweitert. Das Kapitel "Motorische Erprobung" wurde beispielsweise um umfangreiche Ergebnisse zum Thema Reibleistungsmessungen und OElverbrauchsmessungen erganzt.

Heat engines that use gases as the working fluid in a closed system model were discussed in this book. Otto cycle, Diesel, Miller, and Dual cycle are internal combustion engines. Stirling cycle is an external combustion engine. The Otto cycle is a spark-ignition reciprocating engine made of an isentropic compression process, a constant volume combustion process, an isentropic expansion process, and a constant volume cooling process. The thermal efficiency of the Otto cycle depends on its compression ratio. The compression ratio is defined as r=Vmax/Vmin. The Otto cycle efficiency is limited by the compression ratio because of the engine knock problem. The Diesel cycle is a compression-ignition reciprocating engine made of an isentropic compression process, a constant pressure combustion process, an isentropic expansion process, and a constant volume cooling process. The thermal efficiency of the Otto cycle depends on its compression ratio and cut-off ratio. The compression ratio is defined as r=Vmax/Vmin. The cut-off ratio is defined as rcutoff=Vcombustion off/Vmin. The Dual cycle involves two heat addition processes, one at constant volume and one at constant pressure. It behaves more like an actual cycle than either Otto or Diesel cycle. The Lenoir cycle was the first commercially successful internal combustion engine. The Stirling cycle and Wicks cycle are attempt to achieve the Carnot efficiency. The Miller cycle uses variable valve timing for compression ratio control to improve the performance of internal combustion engines.

Britains favourite steeplejack and industrial enthusiastic, the late Fred Dibnah, takes us back to the 18th century when the invention of the steam engine gave an enormous impetus to the development of machinery of all types. He reveals how the steam engine provided the first practical means of generating power from heat to augment the old sources of power (from muscle, wind and water) and provided the main source of power for the Industrial Revolution. In Fred Dibnahs Age of Steam Fred shares his passion for steam and meets some of the characters who devote their lives to finding, preserving and restoring steam locomotives, traction engines and stationary engines, mill workings and pumps. Combined with this will be the stories of central figures of the time, including James Watts - inventor of the steam engine - and Richard Trevithick who played a key role in the expansion of industrial Britain in the 18th and 19th centuries.

Solar energy is derived ultimately from the sun. It can be divided into direct and indirect categories. Most energy sources on Earth are forms of indirect solar energy, although we usually don't think of them in that way. Coal, oil and natural gas derive from ancient biological material which took its energy from the sun (via plant photosynthesis) millions of years ago. All the energy in wood and foodstuffs also comes from the sun. Movement of the wind (which causes waves at sea), and the evaporation of water to form rainfall which accumulates in rivers and lakes, are also powered by the sun. Therefore, hydroelectric power and wind and wave power are forms of indirect solar energy. Direct solar energy is what we usually mean when we speak of solar power -- it is the use of sunlight for heating or generating electricity. Solar energy research and applications have been receiving increasing attention throughout the world as solar energy must play a much greater role in the energy mix in upcoming years. This book examines new research in this frontier field.

The story of how diesel engines and gas turbines, used to power cargo ships and jet airplanes, made today's globally integrated economy possible. The many books on globalization published over the past few years range from claims that the world is flat to an unlikely rehabilitation of Genghis Khan as a pioneer of global commerce. Missing from these accounts is a consideration of the technologies behind the creation of the globalized economy. What makes it possible for us to move billions of tons of raw materials and manufactured goods from continent to continent? Why are we able to fly almost anywhere on the planet within twenty-four hours? In Prime Movers of Globalization, Vaclav Smil offers a history of two key technical developments that have driven globalization: the high-compression non-sparking internal combustion engines invented by Rudolf Diesel in the 1890s and the gas turbines designed by Frank Whittle and Hans-Joachim Pabst von Ohain in the 1930s. The massive diesel engines that power cargo ships and the gas turbines that propel jet engines, Smil argues, are more important to the global economy than any corporate structure or international trade agreement. Smil compares the efficiency and scale of these two technologies to prime movers of the past, including the sail and the steam engine. The lengthy processes of development, commercialization, and diffusion that the diesel engine and the gas turbine went through, he argues, provide perfect examples of gradual technical advances that receive little attention but have resulted in epochal shifts in global affairs and the global economy.

Most industrial and natural materials exhibit a macroscopic behaviour which results from the existence of microscale inhomogeneities. The influence of such inhomogeneities is commonly modelled using probabilistic methods. Most of the approaches to the evaluation of the safety of structures according to probabilistic criteria are somewhat scattered. This text attempts to present such material in a coherent and up-to-date form, and also defines the great tasks that must be tackled in coming years. The text is suitable for engineers and researchers dealing with materials, geotechnics, solid mechanics, soil mechanics, statistics and stochastic processes. The expository nature of the book means that no prior knowledge of statistics or probability is required. The book aims to serve as an introduction to the nature of applied statistics and stochastic modelling.
