The Detroit Diesel Series 60 EGR Technical Manual is a comprehensive guide designed for technicians and mechanics working on the iconic Series 60 engine, a mainstay in the trucking industry renowned for its power and durability. This manual is an indispensable resource for anyone involved in the repair, maintenance, and troubleshooting of these engines, offering in-depth information on every aspect of their operation, from basic engine principles to advanced emission control systems. It encompasses a wide range of topics, including detailed descriptions of engine components, wiring diagrams, troubleshooting procedures, and step-by-step instructions for performing various maintenance tasks. The manual also incorporates detailed specifications, charts, and illustrations to facilitate a thorough understanding of the engine's design and function.

The Detroit Diesel Series 60 engine, introduced in 1987, was a revolutionary design that redefined heavy-duty truck performance. It featured a 14.0-liter, six-cylinder engine with a lightweight, aluminum block, making it lighter and more fuel-efficient than its predecessors. The Series 60 engine quickly gained popularity for its impressive power output, reaching up to 600 horsepower, and its remarkable reliability. However, evolving emissions regulations led to the implementation of exhaust gas recirculation (EGR) technology in later models. This system, designed to reduce nitrogen oxide (NOx) emissions, recirculates a portion of exhaust gases back into the combustion chamber, lowering combustion temperatures and reducing NOx formation. The EGR Technical Manual delves into the intricate workings of this system, providing technicians with the knowledge necessary to diagnose and rectify any issues related to EGR performance. This manual is an invaluable tool for anyone seeking to maintain the peak performance and longevity of the Detroit Diesel Series 60 engine.
