摘要： A fuel delivery apparatus is proposed for mixture-compressing, externally ignited internal combustion engines, which serves to meter a fuel quantity adapted to the quantity of air induced and to regulate the fuel-air mixture in accordance with operational characteristics of the internal combustion engine. The fuel delivery apparatus comprises a fuel metering system actuated by an air measuring element arranged in the air induction line of the internal combustion engine, while the air measuring element has a control body which controls the size of the air induction tube cross-sectional area, a radial vane which is pivotably fixed in a work chamber, and a damping vane fixed in a damping chamber. The radial vane separates the work chamber into partial chambers and is impacted upon by the pressure upstream and downstream of the control body in such a manner that a force engages the radial vane which is capable of moving the control body in the direction of an enlargement of the controlled induction tube cross-sectional area and which acts counter to a return force. The damping vane separates the damping chamber into a pressure chamber and a throttle chamber; the pressure chamber is connected with atmospheric pressure or with the pressure upstream of the control body, and the throttle chamber, into which the damping vane moves during an opening movement of the control body, is connected with the pressure chamber via a throttle point. The throttle chamber and/or the pressure chamber of the damping chamber are capable of being connected with the induction tube section downstream of the control body by means of contro valves in accordance with operational characteristics of the internal combustion engine, for the purpose of influencing the fuel-air mixture furnished to the internal combustion engine.

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 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： 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： An electromagnetically actuatable valve is proposed, which serves in particular to inject into the intake tube a mixture-compressing internal combustion engines with externally-supplied ignition. The valve includes a flat armature which is firmly connected with a ball arranged to cooperate with a fixed valve seat. The flat armature is pivotably supported on its end remote from the valve seat on a spring tongue preferably embodied out of a remnant air disc. A tubular inflow stub is disposed concentrically to the valve axis, communicating on one end with a fuel distributor line and on the other end protruding as deeply as possible into the valve. A tubular outlet stub leading away from the valve seat is concentrically guided in the inlet stub, and arranged to have its end remote from the valve seat discharge into a fuel return flow line. As a result, a cooling of the valve and the return of heated fuel which contains vapor bubbles to its supply source is assured.

摘要： An internal combustion engine is proposed which operates on a lean fuel-air mixture. The engine comprises an inlet channel which leads to the cylinder with a piston and which opens into the cylinder via an inlet valve. A flap element pivotably mounted about a pivot axis which is seated on one side is disposed in a section of the inlet channel; said section having a rectangular cross-section. The flap also has a rectangular cross-section and is used to produce a rotating flow in the cylinder in operating states other than full load. Displacement of the flap can be effected against the force of a spring by the suction air or by a servomotor controlled by an electronic control device as a function of the operating parameters of the internal combustion engine such as rpm flap position and temperature. The fuel is injected by means of an injection valve downstream of the flap such that when the inlet valve is open there will be formed in a depression in the piston firstly a horizontal layer of a rich fuel-air mixture which can be ignited by a spark plug and above it leaner mixture layers.

摘要： A fuel injection apparatus for mixture-compressing, externally ignited internal combustion engines with continuous injection into the air induction line adapted to apportion a quantity of fuel proportional to the quantity of induced air and to accomplish good preparation of the fuel-air mixture. The fuel injection apparatus comprises an air flow rate meter arranged in the air induction tube, which moves in accordance with the quantity of air flowing through it against a return force and thereby actuates a fuel apportionment valve. Accordingly, the apportioned fuel flows into a fuel feed line downstream from the fuel apportionment point, which fuel feed line empties on the one side into the air induction line and is connected on the other with a source of air. The pressure differential at the fuel apportionment point is capable of being maintained constant by means of a differential pressure valve, whose movable valve part is acted upon on the one side by the fuel pressure upstream of the fuel apportionment point and on the other side by air pressure in the fuel feed line at the fuel apportionment point. In order to enrich the fuel-air mixture during acceleration, the pressure in the fuel feed line can be expeditiously increased, so that a sufficient pressure differential is available for the injection of the fuel-air mixture at the opening of the fuel feed line into the air induction line.
