Claims

[Scope of utility model registration request]

A fuel injection pump that includes a fuel supply amount control member and controls the flow rate of fuel supplied to the diesel engine according to the amount of displacement of the fuel supply amount control member; In a control device related to an intake control valve that controls the flow rate, when the engine is stopped, the intake control valve is allowed to return to a fully closed position, and when the engine is running, the intake control valve is returned to a predetermined small opening position. a variable stopper device that allows the device to move but prevents the device from returning to the fully closed position;
a driving means that includes a driving lever that is drivingly connected to an accelerator pedal and opens the intake control valve when the driving lever rotates in response to depression of the accelerator pedal; the driving lever and the fuel supply amount control member; are connected to each other so as to be relatively displaceable by a predetermined amount, and only when the opening amount of the intake control valve is equal to or greater than a predetermined value, the fuel supply amount control member is displaced in accordance with an increase in the opening amount of the intake control valve, and the fuel supply amount control member is displaced in accordance with the increase in the opening amount of the intake control valve. A related control device for a fuel injection pump and an intake control valve of a diesel engine, having a connecting drive means for increasing the supply amount.
