Abstract: In an external-ignition combustion engine operating with compression of the fuel mixture and continuous injection into the suction duct fuel is measured off by a valve by means of a slider actuated by a suction-responsive plate against a return force provided by fuel pressure and subject to control in dependence on operating characteristics of the engine. A pressure-control valve may be subject to a spring bias which is varied by a surface cam in response to throttle position and to pressure downstream of the throttle in the suction duct. A further control in response to engine temperature may be provided.

Abstract: A fuel injection pump wherein the fuel distributing piston moves angularly and axially in synchronism with rotational speed of the engine and cooperates with an adjusting member which determines the beginning or termination of fuel injection into the cylinders. The adjusting member forms part of a transducer which is installed directly in the housing of the fuel injection pump and further includes an electromagnet having a rotary armature which is operatively connected with the adjusting member to position the latter in dependency on the intensity of signals which energize the electromagnet and are furnished by an electronic control circuit. The intensity of such signals, and hence the position of the armature, is a function of rotational speed of the engine, position of the gas pedal, and other factors.

Abstract: A fuel injection system for externally ignited, gas internal combustion engines. The system involves the continuous injection of fuel into an induction tube section of an intake manifold. A measuring member and a randomly activatable throttle valve are arranged in series in the induction tube section upstream from the point of fuel injection. The measuring member is displaced by an operating member against a restoring force in accordance with the amount of air flowing through. In the course of its displacement, the measuring member adjusts a mobile part of a valve which is disposed in the fuel line and meters out a quantity of fuel proportional to the quantity of air, when there is constant pressure difference. The restoring force on the measuring member is produced by a pressure fluid which acts on the operating members at least indirectly. Means are provided for adjusting fuel pressure downstream from the metering valve for influencing pressure of the pressure fluid.

Abstract: In a fuel injection valve, in order to ensure that minimal or no fuel pressure is exerted in a closing direction on the valve needle when the latter is in an open position, the supply channel leading from the downstream side of the valve seat to the nozzle openings circumvents the valve needle and the latter, in said open position, hermetically engages with its base face a stationary frontal plate held in the valve.

CPC classification number: F02M45/08
Abstract: In a fuel injection valve, the initial opening motion of the valve needle (advance injection) is effected by the fuel pressure exerting a force directly on the valve needle and also on pistons connected therewith. Upon a predetermined displacement, the valve needle, by means of a control groove provided therein, cuts off the pressure supply to said pistons so that an elevated pressure level is required to cause further displacement (main injection) of the valve needle.

Abstract: In the air suction tube of a fuel injection system associated with an internal combustion engine, there is displaceably held a control member which regulates a flow passage section for the air and meters the fuel in response to the change in the flow rate of air in the suction tube. The change in the static air pressure due to the change in the flow rate is utilized as an input force to control a servocircuit whose relatively large output force is used directly to displace said control member.
