This new book focuses on both two- and four-stroke reciprocating engines with particular emphasis on their characteristics and the materials used in their construction. It considers the engine in terms of each specific part and covers the metallurgy, surface modification, wear resistance and chemical composition of each engine constituent. The text includes supplementary notes and will be essential reading for engineers and designers of engines as well as for graduate students in the fields of combustion engineering, machine design and materials science.
