This patent describes a fuel injection apparatus including a fuel injection pump which is adapted to carry out fuel intake, fuel pressurization, fuel injection and draining of cut-off fuel in accordance with the reciprocal movement of a plunger. The plunger is driven in synchronization with the rotational operation of an internal combustion engine. The apparatus comprises: a first storing means for temporarily storing cut-off fuel drained at the same time of the termination of the fuel injection; a second storing means of changeable volume for temporarily storing fuel for intake, the second storing means having a movable member which is movable in response to the quantity of fuel introduced therein; a detecting means for producing a detection signal relating to the amount of fuel stored in the second storing means; a clamping means responsible to an electric signal for clamping the movable member; and a signal producing means for producing at least one condition signal relating to the operating condition of the internal combustion engine.
