Students are taught the general concepts of diesel systems technology. Technicians in this field repair and maintain diesel equipment, such as trucks, buses and construction equipment. This includes bulldozers, earth movers, cranes and other dieselpower equipment.
Diesel technicians use common hand tools like pliers, wrenches and screwdrivers, as well as special tools. They also may use testing equipment like dynamometers-which measure engine power, special fuel injection equipment and electronic-controlled engines.
