To reduce the amount of black smoke mixed in exhaust during hot starting of an engine while controlling the cost increase of a governor.
A governor input lever 7 connected with a fuel metering rack of a fuel injection pump is connected to a speed control lever via a governor spring, and a governor sleeve 14 is fitted slide-free onto a governor shaft 15. The governor input lever 7 is made to contact an end face of the governor sleeve 14. In cold starting of an engine, the fuel metering rack is energized to be located at the start-up extension position. In hot starting, the wax 44 filled in an inner space 43 of the governor sleeve 14 melts and expands and thereby the governor input lever 7 is pushed by the governor sleeve 14 towards the side of decreasing fuel and the fuel metering rack is moved to a start-up extension control position which is displaced from the start-up extension position toward the side of decreasing fuel.
