Abstract: A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up. Various embodiments are presented.

Abstract: A fuel injection pump is proposed, which has a centrifugal governor disposed in the suction chamber of the fuel injection pump, the governor having a sleeve displaceable on a piston, and a pressure chamber enclosed in the interior of the governor sleeve, the latter being defined by the end face of the piston. By means of a relief line of the pressure chamber which is opened in the offset position of the governor sleeve, the restoring force on the centrifugal governor is increased during starting by the amount of the pressure difference appearing at the governor sleeve. Beyond a predetermined adjustment of the governor sleeve, the relief line is blocked, so that the governor can function unhindered within the normal operational range. The hysteresis thus resulting upon the shut-off of the increased starting quantity improves the behavior of the engine as it runs up to operational speed.

Abstract: A fuel injection pump is proposed in which the quantity adjustment member has a travel limitation device in the form of an adjustable stop, which is adjusted in accordance with the displacement of an adjusting piston in accordance with a contour formed in the jacket face thereon. The displacement of the adjusting piston is effected via rpm-dependent pressure of the suction chamber counter to the force of a restoring spring and counter to a pressure which can be established with the aid of a pressure control valve in accordance with engine operating parameters. The adjustment of the stop is thus effected with the high work capacity of the suction chamber pressure, and the limitation of the adjustment is attained with the aid of the modulated pressure diverted from the suction chamber pressure.

Abstract: The invention relates to a fuel injection system having a pump/nozzle for which the fuel is metered by one apparatus and the injection onset is determined by a second apparatus. In accordance with the invention, these apparatuses each operate with a distributor, both distributors being combined into a single structural unit. Because of this combination, structural possibilities are created which, both functionally and in terms of manufacturing cost, represent substantial improvements in the field of injection systems.

Abstract: An apparatus is described for controlling recirculated exhaust gas quantities in self-igniting internal combustion engines which have a fuel injection pump. Two parameters, the rpm (preferably via the rpm-dependent suction chamber pressure) and the position of the quantity-adjusting device, are obtained from the fuel injection pump and delivered to a performance-graph memory in which a control value for the recirculated exhaust gas quantity is stored in accordance with these parameters. A recirculated exhaust gas quantity control device is actuated in accordance with the recalled control value.

Abstract: The fuel channel leading from the pressure chamber of a fuel injection pump to the injection nozzles includes a volume containing a valve spring and formed by a cap threadedly engaging the valve body. This cap also provides an axial force which clamps internal elements of the valve mechanism into firm and sealing contact. An elastic insert, whose contours are similar to those of the cap, is located within the cap. This insert deforms under the force of the threaded cap and provides an elastic force reservoir which maintains the clamping and sealing force even when the cap is slightly loosened.
