MODERN DIESEL TECHNOLOGY: LIGHT DUTY DIESELS, Second Edition, provides a thorough introduction to the light-duty diesel engine, the engine of choice to optimize fuel efficiency and longevity in workhorse pickup trucks, refrigeration units, agricultural equipment and generators. While the major emphasis is on highway usage, best-selling author Sean Bennett also addresses current and legacy, small stationary and mobile off-highway diesels. Using a modularized structure, Bennett helps readers achieve a strong conceptual grounding in diesel engine technology while emphasizing hands-on technical competency. The text explores current diesel engine subsystems and management electronics in detail, while also providing a solid foundation in mechanical engine systems. All generations of CAN-bus technology are covered, including the basics of network bus troubleshooting. The author uses simple language to make even complex concepts easier to master and focuses on helping readers gain the knowledge and expertise they need for career success as diesel technicians, including addressing ASE A9 task learning objectives in detail.
