Abstract: In a governor device of a diesel engine, a control rack of a fuel injection pump is adapted to be controllably actuated by a balance between a governor spring and an engine revolution speed responsive means. A speed control member is adapted to be manipulated for adjusting a tension force of the governor spring. A fuel limiting actuation member serves to prevent an excessive fuel flow from being injected when the speed control member is manipulated for a quick acceleration. A quick acceleration state detecting means serves to detect a quickly accelerated state of the engine so as to selectively change over the fuel limiting actuation member to a fuel limiting position and to a fuel limitation cancelling position depending on the lapse of time.

Abstract: For the sake of improving quiet operation during idling and at low partial load by lengthening the injection duration, a fuel injection pump for internal combustion engines has a relief conduit originating in a pump work chamber, the relief conduit including a throttle and being blockable at upper partial load, full load and openable by a control slide. The relief conduit is controlled by a pressure maintenance valve, the opening pressure of which can be adapted from outside to the opening pressure of injection nozzles. The control slide is controlled by a centrifugal governor in such a manner that at idling and lower partial load. The control slide is shifted by the pressure in a fuel low-pressure chamber into its operating position that uncovers the relief conduit, and at upper partial load, full load and starting, the control slide is disconnected from the low-pressure chamber, so that it can drop back into its basic position that blocks off the relief conduit.

Abstract: A liquid fuel pumping apparatus includes a centrifugal weight mechanism 14 which is coupled to a fuel control member through a lever. A spring is provided to oppose the action of the weight mechanism and this is coupled through a lever having an adjustable pivot point, to the lever through a closure member carried about an axially movable member coupled to the weight mechanism. A drilling in the member is supplied with liquid under pressure at a restricted rate. The pressure of liquid acts upon the closure member to urge the closure member relative to the member so as to uncover a groove communicating with the drilling. The pressure of liquid in the drilling is controlled so that it varies in accordance with the square of the speed and in the event that the pressure fails the closure member and the axially movable member will move relative to each other to cause a reduction in the fuel supplied by the apparatus.

Abstract: In a centrifugal governor for use with an internal combustion engine, means is provided which is adapted to bring an adjusting member into urging contact with a fuel quantity increasing lever engaging the guide lever and the floating lever only at engine full load in medium and high engine speed ranges, whereby contraction of the adaptation spring causes angular displacement of the fuel quantity increasing lever in the fuel quantity increasing direction. Stopper means may also be provided which is adapted to be in urging contact with the fuel quantity increasing lever in the medium and high engine speed ranges to prohibit angular displacement of the fuel quantity increasing lever in the fuel quantity decreasing direction which is caused by the contraction of the adaptation spring, when the adjusting member is positioned off the fuel quantity increasing lever at engine partial load.

Abstract: A start lever (56) and a tension lever (18) are rotatable about a pin (19). The tension lever (18) is connected to a fuel control sleeve (28) so that an amount of fuel pumped and injected into an engine depends on the position of the tension lever (18) and sleeve (28). Upon rotation of flyweights (13), a governor rod (52) is urged through a hole (54) in the start lever (52) toward the tension lever (18) against the force of a start spring (22). A flange (53) formed on the governor rod (52) abuts against the start lever (18) so that the force of the start spring (22) is transmitted to the flyweights (13). The end of governor rod (52) abuts against the tension lever (18) at a certain engine speed so that further movement of the governor rod (52) is opposed by a governor spring (26) connected to the tension lever (18).

Abstract: A boost compensator controls the position of a fuel injection control rack in response to the induction air pressure and a centrifugal flyweight assembly increases the fuel injection volume when the engine speed is below a predetermined value. The boost compensator is provided with a releasing spring so that the control rack can be moved by the flyweight assembly independently of the boost compensator. An engine oil pressure sensor provides a maximum fuel injection volume for starting the engine when the oil pressure is zero and automatically decreases the fuel injection volume as the engine starts and the oil pressure rises to an operating value.

Abstract: A limiting speed mechanical engine governor has a speed responsive fuel decreasing mechanism opposed by a high speed spring, the effective force of which controls the maximum governed speed of the engine. A speed adjuster, such as an air actuated piston, is arranged to act against the operative end of the high speed spring to controllably reduce its preset speed setting force and thus provide for controlled reduction of the maximum governed speed of the engine. A control system is disclosed for use on a vehicle, such as a diesel engine powered truck, to permit using the variable maximum speed capability of the governor as a road speed control for the vehicle or to provide a reduced controlled engine speed for operating engine driven accessories when the vehicle is stationary.
