Abstract: The present invention relates to a fuel injection amount control system for a diesel engine to control a fuel injection amount electrically by an electronic-hydraulic governor. In the invention, when a driver steps on the accelerator at 100% in acceleration to raise the engine speed suddenly and vigorously, a DC linear motor transfers a control rack to the full-rack position according to the engine speed to bring the necessary amount of fuel injection. The process is that the rack position detects the second rack position firstly and the control rack leaves the second rack position accordingly, then the DC linear motor suspends the control rack at the first rack position for a certain time under a signal, afterwards and the control rack is positioned to the full-rack position by another command given to the DC linear motor to operate again.

Abstract: A prestroke controller 31 for an engine fuel injection pump 30 utilizes a magnetic coupling 26 and, by taking advantage of the fact that the secondary side (driven side internal magnet) of the magnetic coupling can be controlled to a desired position without being driven by force from a flyweight 11 on the primary side (driving side external magnet), not only secures speed timer characteristics but also provides a greater degree of freedom in determining the injection timing advance characteristic. The prestroke controller 31 includes the magnetic coupling 26 as a member of a displacement transfer section provided between the flyweight 11 and the timing control rod 6 and also includes an add-on device 36 for injection timing advance adjustment which can be engaged with or disengaged from the timing control rod 6 and is capable of controlling the prestroke independently of the magnetic coupling 26.

Abstract: A distributor type fuel injection pump has a rotary magnet regulator (15) to actuate a control member (14) determining the fuel injection quantity, which rotary magnet regulator (15) is driven by a regulating signal produced in dependence on the operational parameters of the internal combustion engine. The rotary magnet regulator (15) is accommodated in a chamber (16) forming part of the pump housing (17) and filled with fuel. A damping device (25) is provided for the purpose of avoiding rotary oscillations of the rotating armature (20) in the rotary magnet regulator (15), which damping device (25) consist of a paddle (26) fixed firmly to the rotating armature (20) and of two separating walls (27,28) provided in the chamber (16). The paddle (26) extends radially from the rotating armature (20) and nearly fills the entire clear cross-section of the chamber (16) available for the swing movement of the paddle. The separating walls (27,28) separate a chamber section (161) comprising the entire range of swing of the paddle (26) from the remaining chamber section (162), whereby however throttle openings ensure a flow of fuel between the chamber section (161) and the chamber section (162) (FIG. 2).

Abstract: An inexpensive type of linear solenoid actuator for moving a plunger along a straight line, while providing a force on the plunger due to the actuator which does not vary greatly over the length of stroke of the plunger; a spring opposes the force exerted on the plunger by the solenoid, so that the plunger will assume any of a range of positions in response to different currents through the solenoid. The plunger has a first larger portion of magnetic material sliding in a first bearing; a tapered second magnetic portion extending forwardly from the first portion; a magnetic third portion of substantially cylindrical form extending forwardly from the tapered portion; and a front non-magnetic portion sliding in a second bearing and supporting the front end of the plunger. The second bearing is in a magnetic end piece having substantial axial width. The stroke of the plunger is preferably such that the forward end of the magnetic third portion moves from a first position near the adjacent end of a magnetic end piece in which the second bearing is mounted, to a second position well within or outside the other end of the magnetic end piece.

Abstract: An electric control device in the form of a final control element for fuel injection pumps for internal combustion engines is protected in the interior of its housing from having the parts it contains inundated by lubricant originating in the interior of the injection pump. This protection is effected in that a suction device driven by the camshaft is disposed in the interior and aspirates lubricant originating in the injection pump and returns it then. The suction device has a rotating part driven by the camshaft, and at its lowest point in the sump it has a sliding shoe which under spring pressure rests at the rear on the rotating part and is so embodied that lubricant adhering to the rotating part reaches a gap and from there is transported back into the injection pump via a drainage hose containing a check valve.
