    摘要: The invention is directed to a flow sensor having a heater, two temperature measuring sensors, a heater temperature sensor and a medium temperature sensor. A control circuit is provided which controls the overtemperature of the heater in dependence upon the temperature of the flowing medium. With this arrangement, the influence of the temperature dependency of the following on the sensor characteristic are compensated: viscosity, thermal conductance and thermal capacity of the medium. The relationship between the heater temperature and the temperature of the medium is adjusted in a slightly nonlinear manner by means of special evaluation circuits. In this way, a further improvement of the temperature compensation is obtained.

    摘要: When an air flow rate meter is used in the intake tube of internal combustion engines, such a meter typically having a flat substrate with at least one resistor film disposed on it, the problem arises of dirt deposits on the substrate end face facing into the flow, which cause undesirable changes in the characteristic curve compared with the calibrated new state of the air flow rate meter. The novel embodiment of the air flow rate member is intended to enable calibration based on conditions expected in practice. To produce the effect, while the air flow rate meter is new, of long-term soiling of an air flow rate meter substrate over a period of operation, a leading body, for instance shaped as a U, is disposed on the end face of the substrate facing into the flow. The leading body simulates a soiled effect while the air flow rate meter is still new, and this effect is taken into account in the calibration. The leading body may be of electrically conductive plastic or lacquer and may be connected to a ground line (15). The air flow rate meter is quite generally suitable for measuring flowing media.

    摘要: An electromagnetic valve consists of two valve housing parts, connected by crimping and axially braced, and having a magnetic pipe care therein. A flat armature is positively connected with a spherically shaped valve closing part, which extends through a central opening in a guide membrane for cooperation with a valve seat. The guide membrane rests via an outer circumference on a collar and is supported there via the axial tensioning force between the valve housing parts in assembled form. The guide membrane is welded to the collar on the outer circumference upon at least two points. Before the valve housing parts are combined, the guide membrane, abutting the collar, in concentrically guided into position by a centering body, having a slightly larger diameter than the valve closing part, on the valve seat and is welded at said points in this position. Thereupon the centering body is removed and the actual assembly of the valve is performed.

    摘要: A fuel injection system for internal combustion systems is proposed, which serves to inject fuel into the intake tube of the engine. The fuel injection system includes at least one fuel injection valve which is disposed in the interior of a holder and communicates with both a fuel supply line and a fuel drainage line. The inflow of fuel into the fuel injection valve takes place radially via an inflow region. An orifice body is secured in the holder, forming a reservoir preceding the inflow region. In the first few seconds after hot starting of the engine, only the fuel stored in the reservoir reaches the inflow region and hence is injected. Because readily volatile fuel components have evaporated beforehand, the fuel stored in the reservoir enables especially good fuel preparation.

The fuel injection valve includes a valve housing, in which a nozzle body having a valve seat is firmly held. Downstream of the valve seat, the fuel is directed via metering fuel guide bores to a preparation bore, which is continued in the form of a preparation bore in an injection sheath. The injection sheath is held on the nozzle body by means of an adapter body surrounding and engaging the nozzle body, and it has an ejection segment within which the inside diameter of the preparation bore decreases in the flow direction toward the ejection end. Teeth are also provided on the ejection segment, pointing toward the ejection end.

    摘要: An injection valve for preparing fuel injected into an intake tube of an internal combustion engine and an injection valve for performing the method are proposed. The injection valve includes a movable valve element, which cooperates with a fixed valve seat, downstream of which the fuel reaches fuel guide bores inclined relative to the valve axis and this fuel discharges into a preparation bore at a distance (a) on the bottom from the wall. The fuel flowing via the fuel guide bores at first exits freely from the discharge openings of the fuel guide bores into the preparation bore and subsequently arrives at the wall of the preparation bore, from where it flows in the form of a film, distributed over the wall, toward the open end of the preparation bore and is ejected into the aspirated air of the internal combustion engine.

    摘要: A temperature sensor is proposed which is intended in particular for measuring the temperature of the air aspirated by an internal combustion engine which operates by electronic fuel injection. The temperature sensor includes a carrier body receiving electrical connections and a temperature-dependent electrical resistor element which is surrounded by a protective sheath. The protective sheath has apertures which permit free access to the temperature-dependent electrical resistor element by the medium to be measured. The protective sheath is advantageously capable of being connected in a positively-engaged manner with a protruding catch of the carrier body. As a consequence of the free access of the medium to be measured to the temperature-dependent electrical resistor element, a very short response time on the part of the temperature sensor to changes in temperature is assured.

    摘要: A device is proposed for measuring the mass of a flowing medium, in particular for measuring the aspirated air mass in internal combustion engines, which has a temperature-dependent resistor disposed in the flow of the medium, the temperature and/or resistance of which is controlled in accordance with the mass of the medium, the control variable serving as a standard for the mass of the medium. The temperature-dependent resistor is embodied as a hot strip or hot wire guided over at least three support points. In order to improve the measurement precision of the hot strip or hot wire and reduce the deposition of dust thereon, the hot element is provided at an inclination relative to the flow direction of the medium.
