This practical book presents fundamental principles and identifies the separate systems (fuel, cooling, etc.). In this revision urgent information is supplied for electronic diesel engines. It explores three fuel systems: low pressure, mechanical, and electronic. Checklists of required maintenance tasks are included, with explanations of engine operation: warm-up, normal running, and shutdown. This guide provides illustrations and step-by-step instructions. The explanation of the basic engine systems and routine tasks presented in Diesel Engines, augmented by the manufacturer's operating manual, puts the actual accomplishment of these jobs well within the capability of even a nontechnical boat owner. Special knowledge and tools are not required.
