摘要： An electromagnetically actuatable valve, especially an injection valve for fuel injection systems which supply internal combustion engines with fuel, is proposed in which the fuel injection valve encompasses a valve chamber and a core upon which a magnetic coil is mounted by means of a carrier body. Fuel supply openings discharge into a flow passage provided around the magnetic coil. Vapor bubbles dissolved in the fuel may be flushed out of the flow passage via a first restriction into fuel return openings which communicate with a fuel return line. On the other hand, the fuel may flow from the flow passage into the collecting chamber which houses a valve component and a valve seat. Vapor bubbles which may appear near the valve component may be flushed out via a second restriction which is provided in the interior of a core to reach the fuel return openings. Thus, disturbances with fuel injection, especially during the "hot start" of the internal combustion engine, are avoided.

摘要： A fuel injection system for internal combustion engines is proposed which serves the purpose of fuel injection into the air intake tube of the engine. The fuel injection system includes a fuel injection valve, which is supported upstream of a throttle valve in a holder body disposed coaxially in the air intake tube. A fuel supply line leads to the fuel injection valve, extending in a downwardly directed manner toward the fuel injection valve and away from a deaeration chamber. A fuel return line leads away from the fuel injection valve, extending in an upwardly inclined direction to discharge into the regulating chamber, disposed at a higher level, of a pressure regulating valve. A fuel feed line originating at a fuel supply pump terminates in an upwardly directed manner into the dearation chamber, which communicates via a dearation nozzle with the regulating chamber, so that vapor bubbles can escape upstream of the injection valve into the return side of the injection valve.

摘要： A fuel injection system is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine in accordance with operational parameters of the engine. The fuel injection system includes a metallic fuel distributor tube, which communicates via at least one branch line with at least one fuel injection valve, wherein the branch line is embodied as a metal tube and is connected with the fuel injection valve by means of a threaded assembly. The material used for the branch line is easily bendable metal. Between the threaded assembly at the branch line and the fuel injection valve, a thin-walled metallic bellows is provided, by means of which a lateral displacement between the attachment point of the branch line at the fuel distributor tube and the installation point of the fuel injection valve is compensated for, and the noise of operation produced by the fuel injection valve is damped.

摘要： A method for mixture formation for mixture-compressing internal combustion engines having a turbocharger and a fuel supply system for performing the method. The fuel supply system serves to regulate the fuel-air mixture in accordance with operating parameters of the engine and includes a first fuel supply element disposed upstream of a throttle valve and a second fuel supply element disposed upstream of a compressor. Below the operating temperature of the engine, fuel is fed only via the first fuel supply element. Above the operating temperature of the engine, the feeding of fuel is effected via the first fuel supply element until such time as the charging range begins, at a predetermined intake manifold pressure (p.sub.um), and above this pressure only via the second fuel supply element. The transition from one fuel supply element to the other takes place in accordance with a predetermined timed function. As a result, good fuel preparation and good cylinder filling are attained.

摘要： A fuel injection valve is proposed which, especially in low-fuel-pressure systems, serves to inject fuel into the intake tube of a mixture-compressing internal combustion engine with externally supplied ignition. The fuel injection valve includes a fixed valve seat cooperating with a movable valve element, downstream of which the fuel to be injected is carried into a mixture guidance channel of a mixture guidance tube and surrounded on all sides with air or exhaust gas for preparation immediately upon its entrance into the mixture guidance channel and injected via an injection opening into the intake tube. The mixture guidance channel may be embodied as tapering in conical fashion toward the injection opening. For the purpose of preliminary preparation of the fuel, secondary air or exhaust gas can already be delivered to the fuel before its entrance into the mixture guidance channel. The fuel injection valve embodied according to the invention assures optimal preparation of the fuel to be injected, even at low fuel pressures, and good running behavior of the engine in the event of abrupt changes in load.

摘要： A fuel injection system is proposed for internal combustion engines having a plurality of injection valves for supplying fuel to the engine. Each injection valve is connected by a yieldable support bracket with a rigid fuel distributor line. The bracket is mounted pivotally with an annular coller secured to the injection valve. The fuel distributor line is arranged to engage rib-like carrier members connected with the internal combustion engine and is held against the carrier member by yielding clamp elements. After the valves are engaged in the sockets of the fuel distributor line and the bore of the cylinder head, then the support brackets are swung upwardly to tension the seal elements that are disposed in proximity to the opposite ends of the valve. As a result, not only a more secure connection between the fuel distributor line and the injection valves is obtained, but also rapid assembly or disassembly of the fuel injection system.

The device has a platelike sensor element which is accommodated in a recess of a sensor carrier, and which with a sensor region that has at least one measuring resistor is exposed to the flowing medium in order to measure its mass. The sensor element is accommodated essentially flush in the recess and is retained in the recess by being glued to a bottom face in the recess. The bottom face of the recess of the sensor carrier has a troughlike indentation, which extends at least partially along the circumference of the sensor element outside the sensor region that has the at least one measuring resistor. The device according to the invention is intended to measure the mass of a flowing medium, in particular for measuring the mass of air aspirated by internal combustion engines.

摘要： A gas flow determination method and a corresponding gas flow determination device. A sensor device including a diaphragm and a frame enclosing it is provided; a predetermined temperature profile is created on the diaphragm; the gas flow to be determined is directed over the diaphragm in a predetermined direction of flow; the change in the temperature profile caused by the gas flow is detected; and the gas flow is determined on the basis of the change thus detected. The temperature at a third location on the diaphragm upstream from the first location and optionally at a fourth location downstream from the second location is regulated at a value corresponding to the local value of the predetermined temperature profile. In this manner, the effect of soiling on the diaphragm may be minimized effectively.

摘要： In a method for reducing the fuel supply for one cylinder of a multi-cylinder internal combustion engine with centralized injection, the procedure is that the cylinder located in the intake cycle sequence in front of the cylinder whose mixture is to be made much leaner, for example because of unreliable combustion, is already supplied with less fuel than is the case when all cylinders are operable. In addition, the intake cycle for the failed cylinder itself is supplied with as little fuel as possible. Using this method, it is possible to set a very lean mixture in the failed cylinder but a mixture having a lambda value close to 1 in the remaining cylinders. This ensures that the motor vehicle in which the internal combustion engine with the failed cylinder is operating can still be reliably operated and, at the same time, there is no risk of overheating of the catalytic converter.
