摘要： A fuel injection device provides a heating element that heats a fuel jet, the heating element being moved temporarily into the fuel jet downstream of a spray opening of the fuel injection valve and otherwise remaining outside the fuel jet. Improved fuel atomization of the fuel jet is thereby obtained or maintained. The fuel injection device can be used, for example, in mixture-compressing, applied-ignition internal combustion engines.

摘要： In known inlet valves, condensation of the fuel, which is precipitated in the form of a wall film, occurs at the inlet valve, in particular when the internal combustion engine is in the cold state. Relatively large fuel droplets, which cause an increase in the harmful components in the exhaust gas, can break away from the wall film. The inlet valve according to the invention has a hollow shaft into which compressed air flows via at least one inlet shaft opening, the compressed air then flowing out again from at least one outlet opening which is provided on one side of the inlet valve facing away from the combustion space of the internal combustion engine. As a result of the outflowing compressed air, an air film is produced around the valve head, which air film prevents condensation of the fuel. The inlet valve is provided in particular for mixture-compressing, spark ignition internal combustion engines.

摘要： An electronic control system for internal combustion engines which has signal generator circuits for the fuel metering and for the ignition. During starting, especially in the case of cold starting, three different phases are provided for controlling the injected fuel quantity and for regulating the fuel quantity downward; furthermore, the ignition angle is adjusted in accordance with temperature and rpm. In terms of the fuel metering, the boundary between the first and second phase is dependent on the rpm or on a maximum total number of revolution cycles, and the end of the second phase is predetermined by a minimum metering signal which is dependent on temperature. In the ignition system, there is an increasing adjustment toward "early" approximately in the rpm range between 200 and 600 revolutions per minute as well as an increasing adjustment toward "late" as the temperature increases.

摘要： A fuel injection apparatus for mixture-compressing, externally ignited internal combustion engines. An air flow rate member, arranged in the air intake manifold is moved against a return force by air flowing through it to adjust a control slide of a metering and distribution assembly arranged in the fuel supply line in order to effect the apportionment of a quantity of fuel which is proportional to the air quantity. The return force is produced by a pressure fluid acting upon the control slide, the pressure of the fluid being variable in accordance with operating characteristics of the internal combustion engine. The control slide has an actuation slide contacting the air flow rate member as well as an apportionment slide, which has a projection with a smaller diameter projecting into an axial throttle bore of the actuation slide and defining a damping space in the throttle bore. The damping space is in communication with the fuel supply line via a gap between the projection and the throttle bore, and there is a bimetallic spring arranged between the apportionment slide and the actuation slide. By this means a richer fuel-air mixture is controlled at the metering and distribution assembly in accordance with the starting temperature, during starting of the engine below a predetermined temperature; the enrichment is lessened after the start in accordance with both temperature and time.

摘要： A control circuit for a fuel-injected internal combustion engine provides a substitute program for generation of fuel injection control pulses during engine starts at low temperatures. The substitute injection control pulses are made dependent on the ambient or engine temperature in the sense that, the lower the temperature, the greater is the length of the injection pulses, i.e., the larger is the quantity of initially injected fuel. The length of the injection pulses also depends on the elapsed duration of the engine starting attempt in the sense of gradually reducing the injected fuel quantity as the unsuccessful engine cranking proceeds. A fully opened throttle during engine cranking signals a flooded engine condition and completely interrupts fuel injection.

摘要： Electrical plug connectors used in humid locations are provided with sealing elements (16, 26) at their cable ends and at their plug ends, which results in an enclosed volume of air in the interior space (27) of the plug connector. If there are fluctuations in temperature and/or pressure in the surrounding space (19), the interior space (27) is at relative overpressure or underpressure; the underpressure situation leads to seepage of water into the plug connector. In accordance with the invention, this is avoided by forming the sealing elements (16,26) of an air-transmissive yet water-repellant material, preferably polytetrafluoroethylene (PTFE), so that they can also serve as pressure equalizing elements. Plug connectors according to the invention are particularly well suited for use in spaces subjected to wide-ranging temperatures and/or to water infiltration resulting from high ambient humidity.

摘要： A fuel injection system for continuous injection to an internal combustion engine has a pivoting air sensor plate with a correction lever that engages a fuel control plunger for metering out fuel in proportion to the air flow. The system also includes a bimetallic, temperature-dependent strip which exerts an opening force on the correction lever when the engine is cold. An electric heater is energized by the starter switch and begins to reduce the force due to the bimetallic strip even before the engine has actually warmed up. A second electric heater of reduced power maintains the strip in disengagement during normal engine operation.

摘要： An injection valve which serves to inject fuel into the intake manifold of a vehicle engine. The valve has a spin chamber upstream of the injection port which can be connected with a return line to the supply pump providing the pressure, for the purpose of continuous maintenance of a spinning motion of the fuel. The closing body of the valve has a projection extending into the injection port and beyond the valve seat which prevents drip formation when the valve opens.
