ELECTRONIC GOVERNOR OPERATION [WL-3]
id0114b5154200
• When electricity passes through the coil, the core becomes magnetized, and the rotor rotates within the regulated limit.
The strength of the magnetization is determined by the input flow of electricity. The magnetic force which occurs in the core causes the rotor to rotate until it balances with the return spring's tension.
• The governor chamber and pump chamber are connected through the magnet filter, and the coil is cooled by the flow of fuel into the governor chamber.
The magnet filter prevents the entry of steel chips into the electronic governor.
• On the tip of the shaft, which is pressed in the rotor, a ball pin is installed eccentrically against the shaft. The ball pin is inserted in the control sleeve hole and the control sleeve position is moved when the rotor is rotated.
• When the electric current output from the PCM as fuel injection amount is large, the electric current that flows in the coil also increases, widening the rotation angle of the rotor. As a result, the control sleeve position moves in the direction that fuel injection amount increases.
