The purpose of the Diesel Technology program is to provide students with training in maintaining, troubleshooting, and repairing heavy-duty diesel powered equipment.  Coursework emphasizes diesel engines, hydraulics, electrical, air conditioning, and diesel fuel injection systems.  The goal of the program is for graduates to be employable as entry-level technicians in a service shop or dealership.  Typical diesel industry employers include truck and automobile dealerships, trucking, bus, and construction companies; and firms that rent or lease trucks.
