摘要： What follows is a description of a fuel injection system for an internal combustion engine which employs exhaust gas recycling. The engine has a suction tube leading to the engine and an exhaust pipe leading from the engine, while the system includes a recycle line connecting both the exhaust pipe and the suction tube, and a control mechanism. The control mechanism can be located either in the suction tube, the exhaust line or the recycle line and controls the pressure therein in order to control the recycled exhaust gas flow rate. The system further has a regulating structure which regulates the quantity of the injected fuel in conjunction with the control mechanism.

摘要： A fuel injection system employing continuous injection into the induction manifold for varying the fuel-air ratio during the warm-up phase of the engine. A pivoting flap responds to the air flow through the induction tube and rotates a metering valve core. Openings in this valve core cooperate with openings in the valve cylinder to form a metering valve aperture of variable cross-section. The pressure differential across this aperture influences the metered fuel quantity and this pressure differential can be varied during the warm-up phase of the engine. The variation in the pressure differential is accomplished by heating a bi-metallic spring which disengages from the closure element of a diaphragm valve, increasing the closing bias thereof. The resulting increase in fuel pressure downstream of the metering aperture displaces a piston which removes the additional biasing force on another diaphragm valve, permitting the reduction of fuel pressure upstream of the metering aperture with the net effect of a reduction of the pressure differential across the metering aperture and a corresponding reduction of the metered fuel quantity, i.e., a leaning out of the fuel-air mixture.

摘要： A fuel injection system for externally ignited internal combustion engines including fuel injection nozzles, a fuel distributor unit, a fuel supply circuit, and a control pressure circuit. The distributor unit includes metering valves, pressure valves and a first throttle which separates the fuel supply circuit from the control pressure circuit. At least one of the pressure valves is embodied as a differential pressure control valve which has one chamber connected to the first throttle and the control pressure circuit. The control pressure circuit includes the above-mentioned chamber of the differential pressure control valve, a magnetic valve, a storage element and a second throttle. With the system noted, the pressure difference across the metering valves may be varied by varying the pressure difference across the first throttle by means of the magnetic valve via the storage element and the second throttle.

摘要： A control device is proposed for regulating the exhaust gas recycling rate in an internal combustion engine with self-ignition in which combustion pressure signals are adjusted directly or indirectly to nominal values dependent on operating characteristics of the engine. In one particular embodiment the combustion pressure signal is differentiated and the frequency of certain occurring amplitude values is adjusted to a nominal value. Owing to the integration of specific combustion processes into the regulation, the device is capable of operating with relatively high precision. It is particularly well suited to compensate for drift phenomena.

摘要： A fuel supply apparatus is proposed which serves to control a mixture-compressing, externally ignited internal combustion engine. The fuel supply apparatus includes at least one fuel depositing point in the air intake manifold, within which an air flow rate meter and an arbitrarily actuatable throttle valve are disposed in series and the air flow rate meter is moved against a restoring force in accordance with the air quantity flowing therethrough. The air flow rate meter, which is embodied as a flat rotary element in the shape of a circular sector, more or less widely opens an aperture which defines the cross-sectional width of the air intake manifold and is rotatably fixed about a rigid shaft extending in the direction of air flow. The intake manifold pressure upstream of the air flow rate meter acts on one side of the air flow rate meter, and the intake manifold pressure downstream of the air flow rate meter acts on the other side of the air flow rate meter. In a plane downstream of the air flow rate meter which is parallel to the aperture, there is an arbitrarily actuatable lobed element, by means of which the flow-through cross-sectional area at the aperture can be varied in accordance with the operating characteristics of the internal combustion engine.

摘要： A continuous fuel injection system for metering out fuel to the induction tube of an internal combustion engine. An air flow metering assembly in the induction tube includes a baffle plate which is set with its plane perpendicular to the air flow vector and is mounted on a shaft which slides axially in bearings. As a result of the air flow, the baffle plate is displaced axially to varying extent and this displacement is opposed by a restoring force provided by pressurized fuel and subject to adjustment on the basis of engine variables. A vaned impeller wheel, mounted on the baffle shaft, causes rotation of the shaft in the bearings, thereby eliminating static friction and preventing hysteresis effects. The centrifugal forces generated by the rotation aid in distributing the fuel and in admixing it with the incoming air.

摘要： In a fuel injection system for an internal combustion engine, a fuel metering valve is controlled by an air sensing element disposed in the air intake tube for metering fuel quantities proportionate to the intake air quantities, and by an electromagnetic valve and an associated control structure which varies the air-fuel ratio by changing the pressure difference across the fuel metering valve, as a function of engine temperature during warmup, then as a function of, for example, the oxygen content in the engine exhaust gases.

摘要： A fuel injection system for externally ignited internal combustion engines preferably has one fuel injection location in the air induction tube (manifold). The metering of fuel occurs independently of the condition of the air prevailing at the injection location, the injection location is disposed ahead of the junction of the air induction tube which leads to the individual engine cylinders. Air is brought to a high velocity by means within the induction tube and impinges, at this high velocity, immediately on the injected fuel, enveloping the same. As a result, the mixture preparation is effected without wetting of the inner wall of the induction tube and the means which bring the air to the required high velocity.

摘要： A fuel injection apparatus for internal combustion engines, in which the onset and end of injection are determined by a hydraulically actuated control slide. The injection pump of the apparatus, which is preferably combined with an injection nozzle to form a pump/nozzle unit, has a pump piston embodied as a differential piston, whose section having the larger diameter serves as an auxiliary pump piston and generates a control pressure (p.sub.S) actuating the control slide. During its compression stroke the control slide, in order to initiate the onset of injection, closes an overflow line leading out of the pump work chamber; and during its return stroke, which is effected by the pressure drop in the control line, the control slide relieves the overflow line in order to control the end of injection. The control pressure (p.sub.S) in the control line necessary for actuating the stroke movement of the control slide is controlled by the closure of this line by means of a control device and is built up during the compression stroke of the auxiliary pump piston.
