摘要： A fuel injection pump is proposed, based on a fuel injection pump of a known type, which has an adjusting member for determining the injection duration and is provided with a throttle device for determining the effective supply stroke of the pump piston. In accordance with the invention it is proposed that the position of the throttle device be varied by means of a pressure control device, which is controllable by signals of an rpm-dependent electronic control unit. The position of the adjusting member determining the duration of injection remains as constant as possible, while the throttle device adjusts the flowthrough cross section of a connecting line leading from the pump work chamber to a fuel withdrawal chamber in accordance with rpm. Thus it is possible, in particular given the small injection quantities required during idling, to effect a uniformly small injection quantity per unit of time during a relatively long injection duration; this results in a substantial reduction in noise.

摘要： A fuel injection apparatus is proposed for mixture-compressing, externally ignited internal combustion engines which serves to apportion a quantity of fuel corresponding to the aspirated air quantity and to effect good preparation of the fuel-air mixture. The fuel injection apparatus comprises a fuel apportionment valve which is actuatable by means of an air flow rate meter arranged in the air induction tube of the internal combustion engine and an arbitrarily actuatable throttle valve arranged downstream of the air flow rate meter. The air flow rate meter has a circular control body, which is rotatably arranged on a bearing shaft with its outer circumference facing in the opposite direction to the air flow and, being transversely arranged with respect to the air induction tube, opens to a greater or lesser degree an aperture which defines the air induction tube cross-sectional area. The air flow rate meter is moved against a return force in accordance with the air quantity flowing therethrough.

The pressure difference prevailing at these valves can be changed by a second, electromagnetic, differential pressure diaphragm valve. The first and second differential pressure valves share a common diaphragm and the pretension of the closing spring in the second diaphragm valve can be adjusted from outside the housing of the fuel metering mechanism.

摘要： A fuel metering system for an internal combustion engine has an arbitrarily settable throttle plate which controls the air flow through the induction tube and an air flow responsive valve element, shaped somewhat like a cylindrical sector, which is pivoted inside the induction tube upstream of the throttle plate. The pivoting valve element has a shaft which is surrounded by a bushing. An opening in the bushing is uncovered to varying extent by a control edge on the pivotal shaft so as to meter out fuel in proportion to the angular excursion of the pivoting valve element. The fuel is delivered to the induction tube directly downstream of the pivoting valve element.

摘要： A fuel injection system for substantially continuous injection into a suction tube of a mixture-compressing, spark plug-ignited internal combustion engine includes a fuel line and a fuel pump. A measuring member and an arbitrarily actuatable throttle flap are disposed, one behind the other, in the suction tube. The measuring member is displaceable in proportion to air quantity and against a resetting force which is normally constant but which is changeable in dependence on engine parameters. A metering valve having a movable part is disposed in the fuel line and coupled to the measuring member. The measuring member actuates the movable part for metering fuel quantity in desired proportion with respect to air quantity. A regulating mechanism, which includes a piston, is actuated in dependence on fuel pressure prevailing downstream from the fuel pump. The piston acts against the force of a spring.

摘要： The air flow rate meter in the induction tube of an internal combustion engine is a pivoting sector which has axial valve elements which cooperate with similar elements in the pivotal shaft to provide fuel metering in proportion to the excursion of the air flow rate meter due to the air flow. Parasitic leakage flow of air past the side walls of the pivoting sector is reduced by providing surface features, such as raised strips or fences, bored depressions, indentations and the like which cooperate with the induction tube wall which may have similar features to induce flow impedance and prevent unwanted air flow past the meter.
