Abstract: A wind power plant has at least one rotor. The rotor has at least two rotor blades and each rotor blade is rotatable about a substantially radially aligned adjustment axis. At least one angle adjustment device is provided for adjustment of the rotor blades. The angle adjustment device has a control disk and at least two cam disks interacting with the control disk. Each cam disk is rotatably mounted about a rotation axis. The rotation axis of the respective cam disk coincides, and is in particular superimposed, together with the respective adjustment axis of the respective rotor blade. The noise development, the maintenance expense, and/or costs of a wind power plant are reduced in that the cam disks are functionally effectively permanently coupled via at least one coupling element.

Abstract: A method and apparatus for injecting fuel into combustion chambers of an internal combustion engine, in which the total injection quantity for the engine is split into a main injection quantity and a small postinjection quantity, the latter being closely coupled to the end of the main injection quantity and being injected with the same fuel pressure as the main injection quantity. This reduces soot emissions at otherwise identical engine operating parameters. Because of the interaction among soot emissions, NO.sub.x emissions and specific consumption, the postinjection, while soot and NO.sub.x emissions are kept the same, can also be employed to lower the specific consumption of the engine.

Abstract: A fuel injection pump for internal combustion engines which has a supply volume adjusting mechanism, being adjustable via a starting lever, an adjusting lever, and a tensioning lever. The starting lever is supported on the tensioning lever via a starting spring, and at non-operation of the engine, the starting spring is supported on a lever stop. To set the optimum amount of fuel to be injected at starting of the engine, which must be reduced at hot start, as opposed to a cold start, the lever stop is forcibly coupled with the adjusting lever such that the lever stop is moved by a swivel movement of the adjusting lever from a first end position to a second end position with the end positions being arranged so that the lever stop forces a starting lever position which in the first end position sets an amount of fuel on the supply volume adjusting mechanism as required for the hot start, and in the second end position, the lever stop sets an amount of fuel as required for the cold start.

Abstract: A fuel injection pump having a speed governor which is housed in a pump body under a control pressure and which actuates an injection quantity control element, and a hydraulic injection timing mechanism which is connected with the pump body and which adjusts the start of injection (SB) to "early" with increasing pressure in the pump body, and to "late" with decreasing pressure. For the implementation of a load-dependent start of delivery (LFB), a governor sleeve of the speed governor governs in a load dependent manner, a relief throttle in the pump body, which, depending on the displacement setting of the governor sleeve, uncovers a varying cross-sectional throttle area to an outlet bore.

Abstract: The apparatus has a fuel injection pump with two partial suction chambers separate from one another. Fuel is delivered to the first partial suction chamber by a second feed pump. A feed pump is associated with the second partial suction chamber, and a reversing valve is disposed between the feed pump and the second partial suction chamber. To inactivate the cylinders of the engine that are associated with the second partial suction chamber, the reversing valve is reversible into a deactivation position, in which the intake side of the feed pump communicates with the second partial suction chamber and the pressure side communicates with the fuel supply tank. Fuel is thus evacuated from the second partial suction chamber by the second feed pump, so that fast inactivation of the associated cylinders is attained.

Abstract: A distributor-type fuel injection pump comprising a mechanical speed regulator in which a tension lever and a starting lever interact as a regulating lever system in such a manner that they act in combination above the idling speed. In such an arrangement a quantity control element is connected to the starting lever and, in addition, this starting lever is engaged by an idling spring. A pretension of the spring can be changed, in dependence on operating characteristics in order to obtain a corresponding change in the delivery quantity during idling, for example with idling overload.

Abstract: An arrangement for controlling fuel flow to an internal combustion engine includes a fuel-injection pump, a fuel tank, and a mechanically driven pre-supply pump for supplying fuel from the fuel tank to the suction space of the fuel injection pump. An electromagnetic control valve located downstream of the pre-supply pump and upstream of the suction space of the fuel injection pump moves between a supply position in which fuel flows from the pre-supply pump into the suction space, and a disconnect position. A mechanically driven additional suction supply pump communicates the suction space with the fuel tank in the disconnect position of the electromagnetic control valve. The electromagnetic control valve has throttle means for communicating the suction space of the fuel injection pump with the inlet of the additional suction supply pump in the disconnect position of the electromagnetic control valve.

Abstract: When motor vehicles are driven, discontinuities that lead to load spikes arise between overrunning and running under load. The load spikes are avoided by means of a discontinuous increase in fuel quantity, which makes it possible for the engine to come gently to rest in its suspension, to bypass the drive play, and to convert the changes in increased fuel quantity without bucking. By incorporating drag elements into the connection between the arbitrary actuation of an intermediate lever, which affects the fuel injection quantity, and an idling stop, a discontinuous adjustment of the intermediate lever is attained.

Abstract: An exhaust-gas recirculating system for internal-combustion engines includes a fuel-injection system which generates a hydraulic back pressure during control of the load- and speed-dependent variation of the beginning of delivery within a given set of load and speed characteristics. An hydraulic back pressure is used directly to control a pneumatic directional valve by means of an hydraulic servomotor. This directional valve, in turn, controls a vacuum-operated exhaust-gas recirculation valve. The hydraulic back pressure is also controlled by means of a pressure-holding valve and a constricting throttle.

Abstract: In a fuel injection pump for internal combustion engines for motor vehicles, a damping device is provided to eliminate so-called vehicle bucking. The device allows rapid adjusting movements of an rpm adjusting lever, which is connected to the driving lever, to affect the supply quantity setting of the fuel injection pump only with a delay. To this end, the damping device has a damping chamber defined by a damping cylinder and a damping piston displaceable therein. The damping chamber communicates with the pump interior via two parallel throttles and via counter-parallel check valves located in series with the parallel throttles. The damping piston is connected to a damper lever on which the rpm adjusting lever is supported via a pre-stressed drag spring.

Abstract: A fuel injection pump, for use with a supercharged internal combustion engine, is provided with a full-load stop that is adjustable by means of a stepper motor in dependence upon operating parameters such as engine speed and manifold pressure. An electrical control device for the stepper motor is housed in a casing which is flange-mounted on the fuel injection pump and cooled by fuel. Electrical transducers for engine speed and manifold pressure are also mounted on the fuel injection pump.

Abstract: An apparatus is proposed for controlling an exhaust recirculation device in internal combustion engines, in which a throttle device in an exhaust recirculation line is opened on the condition that the position of the load-adjusting lever of a fuel injection pump associated with the engine falls below a maximum load position and that the adjusting member of an rpm governor of the fuel injection pump is below a predetermined deflection position and/or is operated above a lower rpm value. With an embodiment of this kind, the control of exhaust recirculation quantities can be performed in a simple and functionally reliable manner for the various operational points of the engine with the greatest possible approximation of the permissible values.

Abstract: An apparatus is proposed for controlling the composition of the operating mixture in internal combustion engines. In this apparatus, a control of the air quantity is effected in accordance with the arbitrarily adjustable fuel quantity by throttling the air intake cross section and by remnant filling of the combustion chambers of the engine by means of recirculated exhaust gas. On the basis of the comparison of the aspirated air quantity with the injected fuel quantity by means of a differential pressure valve, a control pressure building up at a fixed throttle in a discharge line controlled by the differential pressure valve is generated as a control variable for an actuation device of the air throttle valve or for the exhaust recirculation valve in an exhaust recirculation line.

Abstract: An apparatus is proposed which serves the purpose of load-dependent actuation of an adjustment device, wherein the cross section and/or the pressure drop of an exhaust recirculation line in an internal combustion engine can be varied in accordance with load. An injection pump of conventional design is associated with the internal combustion engine and further includes a quantity adjustment device, the position of which acts as a control variable for the load. With this control variable, a booster apparatus is controlled via a comparison apparatus; the output variable of the booster apparatus in turn is the control variable for the actuation of an adjustment device which acts on an exhaust recirculation control apparatus. When a threshold value for load is exceeded, the exhaust recirculation is precluded. The control variable is preferably formed as a fuel pressure signal with the fuel withdrawn from the suction chamber of the injection pump.
