Engine Failure Analysis

Engine failures result from a complex set of conditions, effects, and situations. To understand why engines fail and remedy those failures, one must understand how engine components are designed and manufactured, how they function, and how they interact with other engine components. To this end, this book examines how engine components are designed and how they function, along with their physical and technical properties.

Translated from a popular German reference work, this English edition sheds light on determining engine failure and remedies. The authors present a selection of engine failures, investigate and evaluate why they failed, and provide guidance on how to prevent such failures. A large range of possible engine failures is presented in a comprehensive, readily understandable manner, free of manufacturer bias.

The scope of engines covered includes general-purpose engines found in heavy commercial vehicles, railway locomotives and vehicles, electrical generators, prime movers, and marine engines. Such engines are technical precursors to automotive engines.

This book is for all who deal with engine failures: those who work in repair shops, shipyards, engineering consultancies, insurance companies and technical oversight organizations, as well as R&D departments at engine and component manufacturers. Researchers, academics, and students will learn how even the theoretically impossible can-and will-happen.

Stefan Zima studied mechanical engineering at the Technical University of Berlin (majoring in engines and machines). He came into contact with high-speed, heavy-duty engines for special applications when, after obtaining his intermediate diploma with Deutsche Bundesbahn [German Federal Railways], he underwent training to become an engine driver on diesel locomotives of the V 60, V 1002, V 160, and V 2001 series. After his examination in humanistics, in 1967 he gained his full diploma with a thesis on experimental investigations into a heat-transfer problem. Subsequently, Zima worked as assistant engineer on merchant-navy ships, where he acquired a thorough knowledge of the operation, maintenance, and repair of marine propulsion systems, including those powered by high-speed engines. From 1968 to 1977, Dipl.-Ing. Stefan Zima worked in the R&D division of Maybach-Mercedes-Benz Motorenbau (now: MTU Friedrichshafen GmbH), and was last employed as deputy head of a design department. In 1977 he joined the Giessen-Friedberg University for Applied Sciences as a lecturer in piston engines and head of the IC laboratory. He was appointed professor in 1979. Also during his service as a university lecturer, Zima maintained contact with the everyday world of engine technology in a variety of ways, e.g., by trips on motor ships or by driver training and testing on tracked vehicles (Leopard 1 A 4 combat tank). In 1985 he was awarded his doctorate in engineering from the Technical University of Berlin with a thesis on The Development of High-Speed Heavy-Duty Engines in Friedrichshafen (VDI-Verlag, Düsseldorf, 1987). He published a number of books on internal combustion engines, e. g., Hochleistungsmotoren. Karl Maybach und sein Werk, [Heavy-Duty Engines. Karl Maybach and His Work], VDI-Verlag, Düsseldorf, 1992 and 1995 (co-author); Kurbeltriebe, [Development of the Crank Assembly], Vieweg-Verlag, Wiesbaden, 1999; and Ungewöhnliche Motorkonstruktionen [Unusual Engine Designs], Vogel-Verlag, Würzburg, 2003. Dr. Zima unexpectedly passed away in April 2004. After graduation from high school, Ernst Greuter completed training as a motor vehicle mechanic. After passing his journeyman and master s exams, he attended engineering school. In 1950, he joined his father s business, Motoren-Greuter, an engine overhaul shop located in Saarbrücken, Germany. In that same year, he set up a small subsidiary in Algiers, Algeria, specializing in cylinder boring and crankshaft grinding, with a small sales office. In 1951 he established additional engine overhaul branches in Idar-Oberstein and Mainz, Germany. In 1952 and 1953, Greuter served as an engineer trainee with several vehicle and engine component manufacturers in Germany and abroad. In 1955, he was given overall technical responsibility for all of the family firm s engine overhaul facilities. Also beginning in 1955, Greuter worked as a combustion engines consultant (gasoline and diesel). He participated in research, development, and material testing activities with various engine component manufacturers in Germany and abroad. Greuter conducted tests of new designs and materials on diesel and gasoline engine test stands. In 1964, he established additional subsidiaries in Central and South America, and began license manufacture of ocean-going diesel engines and manufacture of exchange engines. In addition to his work as technical director and managing director of Motoren-Greuter GmbH, beginning in 1975 Greuter operated an engineering and consulting office which specialized in planning and establishing engine repair facilities, exchange engine manufacturing, and production of engine components in Germany and overseas. Additional specialties included personnel training, and combustion engine seminars for the motor vehicle repair trade and for engine specialists.
