ABSTRACT:
A fuel injection apparatus comprises a first storing device for temporarily storing cut-off fuel drained after the termination of a fuel injection, a second storing device of changeable volume for temporarily storing fuel for intake, the second storing device having a movable member which is movable in response to the quantity of fuel introduced therein, a detector for producing a detection signal showing an actural position of the movable member and a clamping device responsive to an electric signal for clamping the movable member. The clamping device is actuated to clamp the movable member in response to the detection signal when the desired amount of fuel is stored therein. The adjusted quantity of fuel stored in the second storing device is supplied to a high pressure chamber together with the cut-off fuel stored in the first storing device during the next fuel intake stroke of a fuel injection pump. As a result, extremely high accuracy control of fuel quantity can be realized.
