ABSTRACT:
A fuel injection pump for an engine comprises a magnetic coupling 37 straddling a partition 36 for connecting a timing control rod 6 and a displacement transfer section 34 of a governor so as to enable efficient transfer of rotational force from the displacement transfer section to the timing control rod without need for an oil seal therebetween, and a prestroke controller for the fuel injection pump 131 includes an injection advance adjustment add-on device 136 for conducting prestroke control independently of the magnetic coupling and thereby provide greater freedom in establishing injection timing advance characteristics by enabling injection timing control in response to temperature or load and/or a safety mechanism 237 for ensuring operation of a governor mechanism 20 based on movement of a flyweight 11 even if the magnetic coupling should stick.
