    • A device for controlling the fuel injection timing of an engine by adjusting the position of a timer piston by means of a solenoid valve, wherein a first frequency signal (W1) or a second frequency signal (W2) whose frequency is lower than that of the first frequency signal (W1) is selectably output by a frequency signal swtiching means (44) based on an engine speed (Ne) detected by an engine speed detecting means (49) with reference to pre-set signal switching engine revolution speeds (N1, N2, N3, N4, N5), and a timer control solenoid valve (39) is duty-controlled by a control means (46) in accordance with the engine running condition at a driving frequency based on this outputted frequency signal, the signal switching engine revolution speeds (N1, N2, N3, N4, N5) at this time being set to values which are different by first predetermined revolution speeds (U1, U2, U3, U4, U5) from an engine revolution speed where the resonance is generated relative to a first frequency (f1) and different by second predetermined revolution speeds (L1, L2, L3, L4, L5) from an engine revolution speed where the resonance is generated relative to a second frequency (f2). Due to this, the fluctuation phenomenon of timer piston in the vicinity of the resonating point is positively restricted.

    • Proposed is a fuel-injection pump in which adjustment of the moment injection begins is carried out by a device (31) which is actuated by the fuel pressure in the interior (12) of the pump, this pressure being controlled as a function of certain operating parameters. The pressure is controlled as a function of engine rpm using prior art techniques and is also increased by means of a first pressure-control device (49), via a pressure-control valve (39), so that, when the engine is cold, the beginning of injection is advanced more than usual. The pressure is also controlled as a function of the load on the engine by a second device (50) so that, when the engine is warm, the beginning of injection is retarded relative to the normal setting. Since this does not produce the required results in all engine-operating regimes, the second pressure-control device (50) is, in addition, controlled as a function of temperature to cut out during cold starting and switch in when the engine is warm, an on/off valve (66) providing additional control when the engine is warm.

    • This invention relates to a device and method for varying the timing of fuel injection for a combustion engine. The device comprises a housing (1) within which two shafts (2, 3) are coaxially arranged and torsionally conjoined by means of splines (6, 7) and a force-transmitting member (5). When the force-transmitting member (5) is displaced, which is partially achieved by means of a hydraulic fluid within the housing, the angular positions of the shafts (2, 3) will be readjusted. Furthermore, the housing (1) contains a revolution sensing device (83, 84) which is movable in a radial direction within a recess (24) which communicate with a pressurized hydraulic fluid. The revolution sensing device (83, 84) controls the flow fhrough the recess (24) in dependence on the number of revolutions. The method deals with the varying of the timing of fuel injection at three different intervals of rotational speed.
