Abstract: A mechanism for the remote distribution/installation of computer programs from a source to a number of target computers. The computer programs are transferred as packages identified in a package list. Attempt numbers for retrying a push mode and a pull mode distribution are pre-specified. A next package is identified in the package list and it is checked if a target computer is available. If it is available then installation of the package on the target computer is started. Otherwise, if at least one push mode attempt is left, a next push mode is resumed and rescheduled and, if no push mode attempt is left, but at least one pull mode attempt is left, a next pull mode distribution is resumed and rescheduled. The mechanism particularly proposes a queue manager that activates a request, i.e., moves the request from a request queue into an active queue, and has implemented throttling that balances the load during a software distribution/installation.

Abstract: A device and a method for controlling an internal combustion engine with an air system are described. At least one variable characterizing the air system is determined on the basis of at least one correcting variable and/or at least one measured variable characterizing the state of the ambient air, using at least one model. The model includes at least one first and one second submodel. Using a submodel, the output variables are determined on the basis of input variables. As input variables of the first submodel, besides at least one output variable of a second submodel, the correcting variable and/or the measured variable are additionally taken into account.

Abstract: The turbine of the exhaust gas turbocharger, which is located in the exhaust gas channel of the internal combustion engine, has a variable geometry. The regulation of the boost pressure is performed via an adjustment of the turbine geometry. A very rapid response of the boost pressure regulation to a variable load, with an overshoot of the specified value, which would damage the turbocharger, being avoided, is achieved by determining a manipulated variable for the turbine geometry as a function of the exhaust gas back pressure prevailing in the exhaust gas channel upstream from the turbine.

Abstract: A method and a device for controlling an internal combustion engine. An actuator serves to influence the quantity of exhaust gas recirculated. A loop controller preselects the quantity of exhaust gas to be recirculated on the basis of a setpoint and an actual value which characterizes the quantity of exhaust gas recirculated. A first measured value is determined in a first position (open) of the actuator, and a second measured value is determined in a second position (closed) of the actuator, with the actual value or a correction value being preselectable on the basis of the difference between the two measured values.

Abstract: In the method for unloading items of laundry from a spin-dryer or washer-dryer (20) which has a perforated operating drum (21) and a drum housing (22) with an end-side unloading opening (26) which can be closed by means of a door (27), after the spin-drying process is finished, the operating drum (21) is set to a speed at which the centrifugal force acting on the items of laundry is still somewhat greater than the force of gravity. The door (27) of the drum housing (22) is opened. The pipe of a suction conveying system is connected to the unloading opening (26) of the drum housing (22). The suction conveying system is activated, and on the drum housing (22) the closure member (29) of an air inlet opening, which is arranged on the peripheral wall, is opened. The method can also be used analogously in tumble-dryers. The device for carrying out the method has the device parts mentioned.

Abstract: The invention relates to a system for controlling an internal combustion engine, in particular a self-igniting internal combustion engine. First means (200) specify a first signal (MLS, US) on the basis of at least one operating parameter (QK, N). Second means (235) specify a second signal (MLI) on the basis of at least the output signal from a lambda probe (125). A third means (220) calculates a third signal on the basis of the first signal and the second signal and applies it to a final controlling element (230). Furthermore, means (515, 520, 530, 610, 235) are provided for the temporal conditioning of the first and second signal.

Abstract: A method for sensing the temperature of the air supplied to the combustion chambers of an internal combustion engine for the purpose of detecting air mass. Air temperature can be measured using an inexpensive detector having a transfer function exhibiting a delayed response. Dynamic performance is improved by applying to the detected temperature a temperature correction value that is obtained by applying a transfer function that is substantially the inverse of the transfer function of the temperature detector.

Abstract: The invention relates to a system for controlling an internal combustion engine (100), in particular a self-igniting internal combustion engine. A signal (U) for triggering a performance-determining final controlling element (105) is stored in a characteristics map (110) for each of a corresponding fuel quantity (QK) to be injected into the engine. The signal values stored in the characteristics map (110) are then corrected in dependence upon a predetermined relationship of a signal corresponding to the value for the fuel quantity (QK) to be injected and a signal corresponding to the value for the actually injected fuel quantity (QKI).

Abstract: In a device for adjusting the injection timing in a diesel engine fitted with EDC, a basic value (SBGWs) of injection timing for operation in the static or steady state is stored in a first characteristic field (20) and a basic value (SBGWd) for operation in the dynamic or unsteady state such as acceleration and deceleration is stored in a second characteristic field (22). These basic values are dependent on desired injected fuel quantity (Q) and engine speed (n). The characteristic field (20) for the static state is designed empirically or otherwise to optimize fuel consumption whereas the characteristic field (22) for the dynamic state is designed for minimum pollutant emission. A gradual changeover from one mode to the other is achieved by the gradual change of a multiplying factor (c) from 0 to 1 or vice versa responsively to dQ/dt departing significantly from zero or becoming zero.

Abstract: The invention relates to a method and arrangement for preparing a fuel-metering signal M for a diesel engine starting with measured variables such as accelerator pedal position, rotational speed, lambda, exhaust gas temperature or torque. A fuel quantity request MW is pregiven in dependence upon the position of the accelerator pedal. This quantity request MW is supplied to a minimum selector together with a second signal. The output signal M of the minimum selector, in turn, determines the metered fuel. The second signal derives from a precontrol characteristic field 50 in dependence upon the speed. The output signal of the precontrol characteristic field MV is influenced by the controller output signal MR in specific operating conditions.

Abstract: A control system for a fuel pump, particularly for a solenoid-valve-controlled fuel pump in the case of a self-ignitable internal-combustion engine, in which at least one pulse transmitter is mounted on the crankshaft and/or on the camshaft. The generated pulse sequences include at least several reference pulses for establishing the beginning of fuel injection, as well as speed pulses for detecting the average and the instantaneous rotational speeds. A trial activation takes place to detect into which cylinder the fuel must be injected. Based on the reaction of the fuel injection system and/or of the internal-combustion engine, it is detected whether fuel was injected into the proper cylinder.

Abstract: The invention is directed to a method and arrangement for controlling a self-igniting internal combustion engine. The arrangement includes at least one measured-value sensor, electronic control unit for forming a quantity signal for metering fuel, and a control unit for driving individual actuators for each cylinder. The actuators determine the quantity of fuel injected by the pump elements into the cylinders. Under specific conditions, a corrective unit is activated which determines corrective values specific to the cylinders for making the cylinders equal. The open-loop control unit applies the metering signal to the actuators in dependence upon the quantity signal and the corrective values.

Abstract: A fuel injection system, in which the injection quantity and the start of injection are controlled with solenoid valves, in view of engine-specific data and various parameters. Rotational-speed pulses are measured at the camshaft and/or at the crankshaft. Trigger times, which establish the start of injection and the injection quantity, are calculated on the basis of the rotational-speed pulses and a start-of-injection reference mark. Based upon an instantaneous rotational speed before the metering-in stage, an estimated value is determined, and based upon an instantaneous rotational speed during the metering-in stage, a control value is determined. The estimated value is compared to the control value and, if need be, the estimated value is adjusted.

Abstract: The invention is directed to a method and an arrangement for controlling the fuel injection in a high-pressure fuel pump. Magnetic valves determine the fuel quantity to be injected into the engine. The magnetic valve is controlled during the pumping phase of the pumping element in such a manner that first a preinjection and then a main injection is carried out. In specific operating conditions, the control apparatus determines the duration of the drive pulses for the magnetic valve at which a preinjection just takes place. With the duration of the drive pulses as a basis, the control apparatus forms compensating signals for the drive pulses which effect preinjection and stores the same.

Abstract: The invention relates to a method and arrangement for controlling the fuel metered to an engine and especially to a diesel engine.

The drive pulses for pump-delivery start and pump-delivery end are generated in dependence upon the analog signal of an angle sensor.
