Fuel and Emission Systems provides an introduction to fuel and emission systems. The course covers operating theory, maintenance, testing, and trouble-shooting techniques. It breaks down the fuel system to its individual components and explains the functions of each. Students learn about the causes of emissions and their harmful effects and about the role of emission controlling devices used in current HD trucks and equipment. Laboratory work supports a hands-on approach in which students work individually or as teams where they apply theory and operating principles and identify the components of the fuel and emission systems.
