Claims

[Scope of utility model registration request]

The tip 12 of the main governor lever 8 is engaged with the fuel injection amount adjusting rack 7 of the fuel injection pump 4 attached to the direct injection diesel engine 1, and the rack 7 is moved through the main governor lever 8 by the governor force G of the governor 13. At the same time, the tension S of the governor spring 15 presses the main governor lever 8 toward the fuel increase side R via the sub-governor lever 9 and the torque spring device 10, and the governor force G and the governor spring 15 In a fuel control device for a direct injection diesel engine, which controls the discharge amount of a fuel injection pump 4 with a tension of
9, a fuel increasing device 16 is formed by incorporating a weak fuel increasing spring 21 and an actuator 18 that is pushed and biased by the weak fuel increasing spring 21.
