摘要： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes metering valves actuatable by means of an air flow measuring device, at which valves a pressure difference can be held constant via control valves and the pressure difference is variable in accordance with operational characteristics of the engine. To this end, the control valves are located on a control pressure line in which a control throttle and an electromagnetic valve are disposed. At the same time, pressure limitation elements communicate with the control pressure line and, in the event of acceleration of the engine, reduce the extent of increase of control pressure and thus assure fuel metering corresponding with the operational state of the engine.

摘要： 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.

摘要： A fuel injection apparatus is proposed for mixture-compressing, externally ignited internal combustion engines which provides continuous injection into the intake manifold. An air flow rate member and an arbitrarily actuatable throttle valve are disposed in sequence within the intake manifold, the air flow rate member being moved against a return force in accordance with the quantity of air flowing therethrough and thereby adjusts the movable member of a metering and distribution valve assembly disposed within the fuel supply line for the purpose of apportioning a quantity of fuel which is proportional to the air quantity. The control slide of the metering valve is actuated by means of a spring which moves in a direction to open the metering valve when the engine is being turned off. Branching off from each fuel injection line there is a scavenging line which is controllable by means of a filling valve provided with a movable valve member which opens a connection from the scavenging line to the fuel tank via a throttle point when the engine is turned off. When the engine is started, the movable valve member is displaced, with a delay, against a return force in the closing direction of the filling valve by means of the pressure of the fuel being supplied, so that the connection of the scavenging lines to the fuel tank is interrupted. Thus when the engine is started, all the fuel lines in the apparatus quickly fill with fuel, and smooth starting of the internal combustion engine takes place.

摘要： A fuel injection system for continuous injection of fuel into the induction tube of an internal combustion engine. The induction tube includes adjacent convergent and divergent regions. A throttling element, composed of two conical parts with adjoining bases forms a narrow, annular aperture in cooperation with the diverging region of the induction tube. The throttling element can slide along its axis and its position determines the setting of a control slide within a fuel metering valve assembly which relates the metered out fuel quantity to the air flow through the narrow annular aperture. A bellows mechanism and a lever limit the axial excursion of the throttle element so as to maintain a minimum vacuum in the induction tube. The system also includes a gas-pedal linked cam plate which sets the location of the fulcrum for the limiting lever.

摘要： A fuel injection system for externally ignited internal combustion engines in which a fuel metering and distributing valve is controlled by an air sensing element disposed in the air suction tube of the engine and by structure which is adapted to alter the restoring force exerted on the air sensing element through the fuel metering and distributing valve. The noted structure includes a control pressure conduit, a pressure control valve connected to the control pressure conduit, a second conduit for connecting the pressure control valve to the suction tube of the engine downstream of the butterfly valve, and a third conduit for connecting the pressure control valve to the atmosphere or to the air suction tube downstream from an air filter. With this structure it is possible to alter the restoring force mentioned above so that an enriched fuel-air mixture is achieved when the butterfly valve is opened to its full load position, and so that a leaner fuel-air mixture is achieved when the butterfly valve is closed to a partial load position.

摘要： The control pressure valve assembly for a fuel injection system of an internal combustion engine provides variable fluid pressure which provides a restoring force against the fuel control plunger to alter the fuel-air ratio in dependence on engine and environmental variables. In particular, the fluid pressure is regulated by a spring loaded diaphragm valve which is also subjected to a variable closing force provided by an air pressure cell and by a first temperature sensitive element which opposes the forces of the spring and of the air pressure cell to provide decreased fluid pressure at low engine temperature and a second temperature-sensitive element to oppose the force of the air pressure cell only below a predetermined temperature.

摘要： A fuel injection system is proposed which can be triggered in such a manner that when control signals characterizing engine overrunning are present the fuel injection is interrupted. The fuel injection system includes metering valves, each of which is assigned one regulating valve, the movable valve element of which can be exposed on one side to the fuel pressure downstream of the pertinent metering valve and on the other side to the pressure in a control pressure line, which is limited on one side by a control throttle and on the other side by a control pressure valve. During engine overrunning, an electromagnetic valve which is disposed in a bypass that bypasses the control throttle or the control pressure valve or an electromagnetic valve in the control pressure line can be controlled in such a manner that the fuel pressure in the control pressure line increases and the regulating valves close, as a result of which the fuel injection is interrupted.

摘要： An apparatus is proposed which serves to regulate the idling rpm of an internal combustion engine. The apparatus includes a bypass line bypassing an arbitrarily actuatable throttle valve in the intake tube. An electromagnetically actuatable bypass valve is disposed in the bypass line for the purpose of controlling supplementary air and is triggerable in accordance with operating characteristics of the engine. In addition, a pressure-sensing adjusting element is also provided, which responds to an abrupt reduction in the intake tube pressure downstream of the throttle device. In accordance with the magnitude of the pressure reduction, this pressure-sensing adjusting element effects a time-limited increase in the supplementary air quantity to the intake tube section downstream of the throttle valve. In the event of an abrupt reduction in the intake tube pressure downstream of the throttle valve, caused by the closure of the throttle valve subsequent to a previous, slight increase in pressure on the gas pedal, the apparatus according to the invention prevents the engine from stopping.

摘要： An electromagnetically actuatable fuel injection valve which serves to supply fuel to a mixture-compressing internal combustion engine having externally supplied ignition. The fuel injection valve includes a valve housing with a mouth piece in which a valve seat body is disposed, two magnet coils two cores and one armature, which has a spherical guide section and is connected to a valve needle. The spherical guide section is slidably supported with its circumference in a guide bore of the valve seat body and in its stroke movement away from the core is limited by a tapering stop opening which adjoins the guide bore. A plastic bushing is mounted on a guide step of the valve seat body and is pressed by a spring against the core end face, thereby preventing a dirct flow of fuel to the remnant air gap on the armature, as a result of which the depositing of soil particles in the gap is avoided.
