MARINE DIESEL ENGINES: Maintenance, Troubleshooting, and Repair (3rd Edition)

Description

More than ten years have gone by since I wrote the second edition of this book. In this time, there have been significant changes in the diesel engine world. Whereas in the past such changes have occurred largely as a result of economic and competitive pressures, in recent years the motivation for change has come from what is known as “technology forcing” legislation, primarily in the form of ever-tightening emissions standards (see the Technology Forcing Legislation sidebar next page). When such legislation is first introduced, many in the industry argue that the new standards will be impossible to meet, but in fact, as each successive deadline has approached, manufacturers have invariably succeeded in exceeding the new requirements. Some will admit off the record that the legislative pressure has been good for the industry.

When first proposed, most of the tightened standards were not applicable to marine engines. But because of the relatively small size of the marine marketplace (approximately 50,000 diesel engines up to 800 horsepower worldwide each year, as opposed to millions of engines in the automotive and trucking industries), many marine diesel engines have always been adapted from other applications, and to the degree that the new standards applied to these applications, the technology found its way onto boats. From about 2004 onward, marine engines have been specifically included in both international and U.S. EPA regulations, with increasingly stringent emissions requirements being phased in over the five-year period from 2004 to 2009. This has resulted in numerous technological changes, most of which are invisible to boatowners, consisting of refinements in materials and design elements that have little impact on operating and maintenance practices. As such the changes have had, and continue to have, little practical impact on most boatowners. The two notable exceptions are electronic engine controls and common rail fuel injection.
