DADD-216: Diesel Engine Accessories

This course covers electronically controlled diesel engine accessories and exhaust emission devices from Caterpillar, Cummins, Detroit, International, Mack, and Mercedes-Benz. Students will learn about diesel powertrain electronics and diagnosis by working on diesel engines using computer-based diagnostic equipment and software. Students will also gain a basic understanding of how the engine microprocessor interfaces with other electronic control units (ECUs) in the diesel powertrain. Electronic troubleshooting and programming procedures for diesel fuel systems, exhaust emission devices and diesel engine accessories, such as the popular Jake brake, will be covered. They will also learn to diagnose problems with intake and exhaust systems, including electronically controlled turbochargers. Students will learn about the operation and maintenance of the exhaust gas recirculation (EGR) systems as well as Caterpillar Advanced Combustion Emissions Reduction Technology (ACERT™) systems and diesel particulate filters (DPFs) from various engine manufacturers.
