    摘要: A fuel injection system is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine. The fuel injection system includes an air flow rate member, which actuates a metering and distribution valve. A reservoir is disposed in a pressure control line which branches off from a fuel supply line, by means of which reservoir a flushing valve can be affected in such a manner that below a certain fuel pressure in the pressure control line the flushing valve is opened, as a result of which the fuel supplied to the individual injection valves can flow back through outflow lines to the fuel tank and thus closes the flushing valve above the certain fuel pressure. Above the certain fuel pressure, the electrical circuit of the starter motor is simultaneously closed. Thus, upon starting the engine, all the lines and units of the fuel injection system are filled with fuel, so that a secure start is assured.

    摘要: A throttle-valve housing of plastic has a metal insert which achieves dimensional stability in the region of the throttle valve. The throttle-valve housing is formed of plastic with a cavity bounded by an inner wall surface. In the wall there is arranged a metal insert which is covered on all sides by the plastic material and effects a stabilization of the plastic material, so that distorting, shrinking or the like is prevented and dimensional accuracy of the inner wall surface is ensured. The novel throttle-valve housing is simple to produce and has a high dimensional stability in spite of being formed from plastic material. The throttle-valve housing is suitable for internal-combustion engines of motor vehicles.

    摘要: A fuel injection system is proposed which serves to adapt the fuel-air mixture as precisely as possible to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, each of which is assigned a regulating valve whose movable valve element can be exposed on one side to the fuel pressure downstream of the respective metering valve and on the other side to a control pressure line defined on one end by a control pressure valve of the nozzle/impact plate type and on the other end by a control throttle. The control pressure valve has a permanent magnet and an electromagnet, the magnetic fluxes of which are guided via an armature in such a manner that in at least one air gap the magnetic fluxes of the permanent magnet and of the electromagnet extend in the same direction, while in at least one other air gap the magnetic fluxes of the permanent magnet and of the electromagnet extend in opposite directions. This kind of embodiment requires a substantially smaller triggering power on the part of the electromagnet. By reversing the exciter current of the electromagnet, the control pressure valve is opened widely enough that the control pressure engaging the regulating valves causes the closure of the regulating valves, and the injection of fuel is precluded.

    摘要: A throttle device having a throttle-flap connection piece which is produced from plastic. For an efficient production of the throttle-flap connection piece form plastic in the plastic injection-molding technique, it is necessary to avoid undesirable shrinkage in the pivoting region of the throttle flap and to seal off the bearing arrangements against penetrating plastic during the injection operation. The throttle device includes an annular insertion part which is arranged in the pivoting region of the throttle flap and which, connected to the bearing arrangements is embedded into the throttle-flap connection piece made form plastic, in order to protect the bearing arrangement against penetrating plastic. The injected-round insertion part is suitable for throttle devices which are made from plastic and which are provided for mixture-compressing spark-ignition or air-compressing auto-ignition internal-combustion engines.

    摘要: A diaphragm pressure regulator is proposed which serves to regulate a fluid pressure in a system having fluid flowing through it, and in particular to relate the fuel pressure in a fuel injection system. The diaphragm pressure regulator includes a valve diaphragm, which cooperates with a valve seat. The valve diaphragm separates a spring chamber having a system pressure spring from a system pressure chamber, into which the valve seat, which is axially displaceable and is supported in an axial bearing point, protrudes and which communicates with the fluid to be regulated. The end of the valve seat remote from the valve diaphragm is embodied as a valve plate and protrudes into a collection chamber, in which it opens a sealing seat toward a return flow line to a greater or lesser extent. A closing pressure spring engages the valve plate and urges the valve seat in the direction of the valve diaphragm. When the valve diaphragm is lifted up from the valve seat, fluid flows via a conduit in the valve seat into the collection chamber. A throttle gap is provided between the system pressure chamber and the collection chamber, by way of which throttle gap fluid can flow out to the collection chamber, when the fluid system is shut off, until such time as the valve plate is pressed in a sealing fashion against the sealing seat and blocks the return flow line, which takes place below a predetermined fluid pressure.

    摘要: A fuel injection system is proposed which can be triggered such that when control signals characterizing engine overrunning are present, fuel injection is interrupted. To this end a pressure relief valve is provided, which opens in the presence of control signals characterizing engine overrunning and lowers the fuel pressure upstream of the fuel metering locations and accordingly upstream of the injection valves as well to below the opening pressure of the injection valves, so that no further fuel is injected via the injection valves during engine overrunning.

    摘要: The temperature of a measuring resistor is controlled for measuring the mass flow rate of intake air entering an internal combustion engine. The operating temperature of the measuring resistor is regulated by controlling the level of electric current flowing therethrough. A voltage signal based on the level of electric current flowing through the measuring resistor is generated which is indicative of the mass flow rate of air entering the engine. The operating temperature target value of the measuring resistor is adjusted based on the value of the voltage signal, to optimize the measurement sensitivity thereof based on the level of the intake air mass flow rate.

    摘要: The device relates to a piston pump, in particular a high pressure pump for a fuel injection device of an internal combustion engine, with at least one piston that is supported so that the piston can slide in a piston guide provided in a housing. A drive shaft is supported in the housing (10) on which drive shaft a crank element is provided. A stroke ring is supported in rotary fashion on the crank element and the piston can be acted upon by the drive shaft by way of this stroke ring. In order to prevent high lateral forces on the piston, the piston is supported on the non-rotating stroke ring with a sliding surface disposed on it against an associated slide bearing surface, wherein lubrication grooves are let into the slide bearing surface, crosswise to the relative motion between the piston and the stroke ring.
