Abstract: The present invention addresses the problem of providing a fuel injection pump (100) that is capable of detecting a valve closing timing even in a state in which the viscosity of the fuel is high and controlling valve behavior. The fuel injection pump (100) provided in a diesel engine is provided with an electromagnetic spill valve (20) that adjusts a fuel injection amount by relieving fuel pressurized by an opening and closing operation of a spill valve body (23) and an ECU (50) that forms a driving current of the electromagnetic spill valve (20), wherein the ECU (50), in a warm state, detects a valve closing timing of the electromagnetic spill valve (20), forms an optimal current waveform of a drive current based on the detected valve closing timing and applies the drive current in the formed optimal current waveform to the electromagnetic spill valve (20), and, in a cold state, applies only a drive current in a preset current waveform to the electromagnetic spill valve (20).

Abstract: There is provided a fuel injection pump that enables white smoke in exhaust gas to be significantly reduced. A fuel injection pump (100) delivers, at high pressure, a fuel to be injected into a combustion chamber of a diesel engine and includes a delivery valve (10) disposed in the middle of a path for pressure-feeding the fuel from a plunger (104) to a fuel injection nozzle. A damping valve (17) is disposed on the downstream side of the delivery valve (10). The damping valve (17) includes a valve element (15) which has an orifice (15a) formed on an axial part thereof and is biased downward (toward the upstream side) by a damping valve spring (18) and a receiving element (16) which has a passage hole (16a) formed on an axial part thereof and abuts against the valve element (15). A recess (15b) which communicates with the passage hole (16a) is formed on a face of the valve element (15), the face facing the receiving element (16).

Abstract: A technology that can extend the life of a fuel injection device of an engine while maintaining its good responsiveness is provided. A fuel injection device 100 for an engine includes: a control rack 55 supported to be slidable in an axial direction and capable of adjusting of a fuel pressure-feed amount of a fuel pressure-feed mechanism unit 51, based on its slide-position relative to the axial direction; an actuator 40 capable of reciprocating its operating unit 41; and a link lever 20 swingably supported by a pivot shaft member 25 and configured to swing in association with reciprocation of the operating unit 41 of the actuator 40 thereby causing the control rack 55 to slide, wherein the fuel injection device includes an actuator-side connecting part 20A connecting an operating unit 41 of the actuator 40 to the link lever 20, and the actuator-side connecting part 20A is positioned on the same axis as the operating unit 41 of the actuator 40.
