The governor device includes an electromagnetic clutch capable of utilizing the driving force of a diesel engine for driving a control rack of fuel injection pumps. The electromagnetic clutch is controlled based on the difference between a preset engine speed and an actual speed. With this device, electrically controlled governor operation can be executed without use of an electric actuator such as a solenoid or the like.

A fuel injection timing control apparatus is disclosed, which comprises a fuel injection timing control mechanism including an input and an output shaft respectively with a first and a fourth gear, at least one of these gears being a helical gear, and an axially movable shaft with a second and a third gear respectively in mesh with the first and fourth gears, a piston-cylinder assembly with a piston rod coupled to the axially movable shaft, and a piston-cylinder assembly control mechanism having detector means for detecting the phases of the first and fourth gears. The phase relation between the first and fourth gears is varied with displacement of the second and third gears caused through control of the piston-cylinder assembly according to the difference between a reference phase angle and a detected phase angle.
