Abstract: A continuous fuel injection system for an internal combustion engine including a fuel metering valve 7 operating at a controlled pressure difference between chambers 13,14, the pressure difference being automatically adjusted by a regulating valve 17 including a diaphragm 18 separating two chambers 19,20. Chamber 20 is connected to relief 60 via a movable valve element 35 and the second chamber 19 is connected to the pressure upstream of the metering valve. The pressure difference is determined by a spring system acting on the diaphragm 18 including a stronger spring 33 which acts directly on the diaphragm and a weaker spring 34 which acts as a contact spring holding the valve body 35 lightly in contact with the diaphragm.

Abstract: An apparatus for controlling the ratio of air to fuel quantity of the operational mixture to be introduced into the combustion chambers of an internal combustion engine which includes an air flow rate meter moving under differential pressure against a constant hydraulic restoring force, which air flow rate meter adjusts a metering cross section in a supply line leading to a fuel injection pump, with the pressure drop at the metering cross section being maintained constant with the aid of a differential pressure valve. The air flow rate meter is part of a known apparatus which controls the fuel component in accordance with the quantity of aspirated air and also controls the component of exhaust gas to be fed back. The hydraulic restoring pressure for the air flow rate meter is drawn via a throttle from the supply side of a supply pump which supplies the injection pump with fuel under an rpm-dependent pressure and with a quantity of fuel intended for flushing and the pressure downstream of the throttle is maintained at a constant value by means of a pressure maintenance valve. The working chambers of the injection pump communicate only with either the injection lines or the fuel supply line controlled by the air flow rate meter, so that the control result is not adulterated by the flushing quantity or by a shutoff quantity. In this manner, the injection pump and the control device can be supplied with fuel and with pressure fluid by means of a single supply pump.

Abstract: The fuel mixture preparation system of an internal combustion engine, especially a continuous fuel injection system, is engaged during intended engine accelerations by a pressure sensor in the induction manifold which responds to increasing manifold pressure to close a switch. The switch closure affects a pressure control valve that changes the control pressure in the fuel injection system and thereby causes temporary fuel enrichment until the differential pressure in the pressure sensor has returned to equilibrium. The signal from the pressure sensor may be extended arbitrarily by interposition of an electronic timing circuit which is constructed as an integrating circuit so that its output signal, when processed by a comparator, will produce a proportionally extended actuation signal for the control valve.

Abstract: A fuel injection system for continuous fuel injection into the induction manifold of an internal combustion engine. Upstream of the main throttle, there is disposed a baffle plate on a pivoting lever which act as an air flow rate meter and displaces the slide valve of a fuel metering assembly in proportion to the air flow rate. An electromagnetic actuator, attached to the induction tube, has a movable armature on which there is disposed a spring. During engine starting at temperatures below approximately 30 degrees C., the restoring force on the air flow rate meter is so low that the force of the actuator spring is able to displace the pivoting lever and the slide valve in the direction of greater fuel delivery, thereby providing cold starting assistance. In other embodiments, the temperature dependence is increased by using a bimetallic spring on the actuator.In a further embodiment, the actuator is attached to the operating lever.

Abstract: A diaphragm valve which may serve as an equal pressure valve or as a pressure equalizing valve of a fuel metering and distributing unit for an externally ignited internal combustion engine. The valve has a flexible diaphragm having a clamped diameter and a pocket in the diaphragm supports a valve plate. The valve plate operatively cooperates with a valve seat of the valve and has an annular recess arranged to receive a spring to center the valve plate. The valve also includes a stationary thrust plate which is concentrically disposed relative to the valve seat, which defines a knife-shaped edge which lies in a common plane with the valve seat and which operatively cooperates with the valve plate. The knife-shaped edge is penetrated by a plurality of radially extending means defining openings therein.

Abstract: A fuel injection system for an internal combustion engine whose air induction tube contains an air flow rate measuring member with non-linear operating characteristics, coupled to a potentiometric transducer which produces the electric command variable for a follower control loop. A control amplifier drives a servomotor which sets the metering slide of a fuel metering valve assembly. The servomotor shaft is coupled to a second potentiometric transducer whose output is compared with the command variable in a bridge circuit connected to the input of the control amplifier. The mechanical link between the servomotor and the fuel metering slide has a non-linearity similar to that of the air flow rate measuring member.

Abstract: A fuel injection system for mixture compressing, externally ignited internal combustion engines includes a fuel distributing unit having a plurality of fuel metering valves, and a plurality of pressure valves. The pressure valves are disposed in the fuel flow path between their respective fuel metering valve and their associated fuel injection valve. Each of the pressure valves includes a space which is divided into first and second chambers by a flexible member. At least one of the pressure valves is embodied as an equal pressure valve, and at least one of the pressure valves is embodied as a differential pressure control valve. The pressure in the second chamber of the differential pressure control valve is the pressure prevailing upstream of the fuel metering valves, and the first chamber of the differential pressure control valve communicates with the second chamber of each of the equal pressure valves so that the pressures therein are equal. Fuel metering occurs at a constant pressure difference.

Abstract: A fuel injection system for an internal combustion engine in which the intake air flow is measured and a corresponding electrical signal is generated which governs a pressure control unit so as to modify the fluid pressure acting on a fuel-metering slide-valve piston, displacing it against restoring forces. The axial displacement of the slide-valve piston changes the flow aperture in adjacent metering slits and thus governs the rate of fuel flow to the injection valves of the internal combustion engine and maintains a desired fuel-air ratio.
