*5.3. Classification of Generator Engine Components*

The systems of diesel engines, which have been most commonly used as driving generators, include the air supply, cooling, lubrication, fuel supply, power, and valve systems, while electric equipment includes electric governors, measuring equipment, control and safety devices, and cooling devices. In the case of governors in particular, electronic equipment is currently used. It receives the signal from the power management system (PMS) and adjusts the engine speed using torque control. Figure 11 shows the generator engine components.
