Here, in this goldmine of a book, is everything the reader needs to keep their diesel engine running cleanly and efficiently. Nigel Calder is the world's foremost writer on boat systems maintenance, and in this extensively illustrated guide, he explains how diesel engines work, defines new terms, and lifts the veil of mystery that surrounds the subject. Troubleshooting charts, hundreds of exploded drawings and detailed photos enhance the clear and logical explanations. This new edition also features completely new photographs and includes updates for fuel injection systems, electronic engine controls and other new diesel technologies and models. As diesel engines have now almost completely supplanted gasoline engines on boats, this guide is an increasingly relevant and important tool for anyone wanting to become their own diesel mechanic.
