摘要： The fuel supply apparatus for supplying fuel to an internal combustion engine has a fuel tank (2), a first fuel pump (6) that supplies fuel from the fuel tank to a fuel line (10), a second fuel pump (12) that supplies fuel from the fuel line (10) via a pressurized line to at least one fuel valve (16) and a fuel return line (22) that connects the fuel line (10) to the fuel tank for return of excess fuel. A shut off valve (30), which is closed at high temperatures, and a pressure regulator valve (26) are arranged hydraulically in series in the fuel return line (22). A fuel scavenger line (60) is provided, by which fuel at high temperatures is returned to the fuel tank (2). The fuel scavenger line (60) conducts the fuel back to the fuel tank (2), at least partially through the second fuel pump (12) and through a hydraulic resistance. Gas bubble formation is prevented by a high fuel supply pressure and by transfer of heat from the second fuel pump (12).

摘要： A piston pump for pumping fuel in which a risk of fuel getting into the area of a shaft seal is limited. The fuel pump includes a separation chamber which is provided between a shaft seal and a fuel chamber that contains fuel. Located in the separation chamber is for instance air as a separator means, and the separation chamber communicates with an air inlet of the engine. This assures that fuel cannot get into the area of the shaft seal or escape to the outside. The fuel pump is suitable in particular for internal combustion engines in which the fuel must be delivered at high pressure.

摘要： A throttle appliances in which induction ducts are configured off-set with respect to the pivoting region of throttle elements, such that metering walls that are provided influence the air throughput at small opening angles of the throttle element in an optimum manner. The throttle appliance is characterized by its extremely accurately matched metering walls in a range of small opening angles of the throttle butterfly in the induction duct. The metering walls are achieved by a method of displacing a rotating chip-cutting element with its center (M) on a previously calculated path (B) in the induction duct in the axial direction with a radial offset. This method permits the manufacture of varied contours of metering walls in order to achieve desired air throughput/opening angle characteristics. The throttle appliance is usually employed in internal combustion engines which are preferably used in motor vehicles.

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： 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： 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.

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.

The channel region is designed in such a way that the ratio of the flow cross-section of the central portion to the smallest cross-section of the venturi section is from 1:8 to 1:25 and the ratio of the cross-section to the cross-section of the inlet and outlet opening is in each case from 1:1 to 1:2.

摘要： An apparatus for actuating a throttle valve secured on a throttle valve shaft in internal combustion engines has an adjusting lever which is seated in a manner fixed against relative rotation on the throttle valve shaft and is actuatable by a pivot lever on the one hand, and on the other, when the pivot lever is stationary, by an electromotive throttle valve adjuster. With a pivot lever bush, the pivot lever is seated on a split taper socket secured to the throttle valve shaft. For restoring the adjusting lever, a decoupling spring is provided, which is disposed on a split guide sleeve surrounding the pivot lever bush and is braced, with its tangentially offstanding spring ends, on the pivot lever and adjusting lever. To avoid friction losses in the rotation of the adjusting lever relative to the fixed pivot lever, the split taper socket protrudes axially on the swivel lever bush, and one sleeve part of the spring guide sleeve is secured to the split taper socket in the protruding region.
