Through a carefully-maintained “building block” approach, this text offers students an easy-to-understand guide to automotive, truck, and heavy equipment diesel engine technology in a single, comprehensive volume. Text focus is on state-of-the-art technology, as well as on the fundamental principles underlying today's technological advances in service and repair procedures. Industry accepted practices are identified; and, students are encouraged to formulate a sound understanding of both the “why” and the “how” of modern diesel engines and equipment.
