If the owner of a diesel engine wants it to run efficiently, proper operation and maintenance are essential. This book focuses on those all-important areas, with the exclusion of overhauls. The book presents fundamental principles and identifies the separate systems (fuel, cooling, etc.). Systems are explained and the required maintenance tasks presented in a checklist format. Safety precautions also are stressed. A separate chapter is devoted to engine operation: warm-up, normal running, and shutdown. Copious illustrations and step-by-step instructions are all p art of the author's clean, well-organized method of presentation. The boat owner need not be an experienced mechanic to perform routine maintenance chores on his or her engine, and special tools are not required. 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.
