Component Description
ELECTRIC GOVERNOR
The electric governor is built into the fuel injection pump. It moves
the control sleeve to increase or decrease the amount of fuel
injected.
When current flows through the coil, a magnetic force is produced,
rotating the rotor. The rotor shaft is installed to the control sleeve
via a ball pin which is eccentrically situated in relation to the rotor
shaft. With this arrangement, the control sleeve can be moved in
relation to rotor rotation.
The rotor's rotating angle is determined by a balanced condition of
magnetic force (generated by current flow regulated by means of
the ECM) and tension of return spring (installed to rotor). The larger
the current flow through the coil, the greater the rotor's rotating
angle. This means that the control sleeve moves to the right,
increasing the amount of fuel injected.
The ECM regulates the current flow through the coil by changing
the duty cycle ratio which controls the ON-OFF operation of the
electric governor grounding circuit.
