摘要： In a method and a device for controlling a brake system, the wheel brake pressure is set at the wheel brakes electrically as a function of the driver's braking input. The high-pressure supply arrangement for pressure buildup, for which at least one pump and one accumulator are provided, is monitored by comparing the change in accumulator pressure to a least one permissible limiting value. In the case of a fault in the pressure supply, it is made possible for the driver to grip through hydraulically to the wheel brakes.

摘要： A method and device for controlling a braking system of a motor vehicle in open loop, in which the wheel-brake pressure in the individual wheel brakes is adjusted via closed pressure-control loops. Different secondary braking operations are initiated depending on the fault condition. The faults are detected on the basis of a model which takes into account the prevailing operating state of the braking system.

摘要： A method for controlling an internal combustion engine having a common rail system together with individual accumulators. A rotational speed-control deviation (dn) is determined from a target rotational speed (nSL) that represents the set point for an outer control loop to control the rotational speed, as well as from an actual rotational speed (nIST). A target torque (MSL) is determined from the rotational speed-control deviation (dn) via a rotational speed controller as a master controller. A target injection duration (SD(SOLL)) is determined from the target torque (MSL). The target duration injection (SD(SOLL)) represents the set point for an inner control loop for controlling cylinder-specific injection duration. An injection duration deviation is determined from the target injection duration (SD(SOLL)) and from an actual injection duration. A correcting variable is determined from the injection duration deviation via an injection duration controller as a follow-up controller, and an injection duration is determined from the correcting variable and the target injection duration for activating the injectors.

摘要： Within an injector housing, a nozzle needle comprising a nozzle needle shaft is accommodated in a first guide boring in a longitudinally displaceable manner. A nozzle prechamber which is arranged in front of the nozzle needle shaft and which is situated on the fore-part of the first guide boring is supplied with fuel via a high pressure channel. A control valve permits a control chamber, which is coupled to the nozzle needle and which is subjected to the action of highly pressurized fuel, to be relieved from pressure by opening the nozzle needle. According to a second embodiment, a spring chamber is configured as a high-pressure chamber on the rear side of the first guide boring that guides the nozzle needle shaft. The spring chamber is separate from the control chamber and contains a readjusting spring that impinges upon the nozzle needle in a direction of closure. This configuration prevents fuel exiting the nozzle prechamber from overflowing over the guide boring which guides the nozzle needle.

摘要： For an internal combustion engine with a common rail system including individual accumulators, a process for open- and closed-loop control is proposed, in which the individual accumulator pressure (pE) is detected within a measuring interval and stored, an absolute minimum value of the stored individual accumulator pressure (pE) is interpreted as the end of the main injection, and on the basis of the end of the main injection, a mathematical function is used to calculate a virtual starting time for the main injection. In the measuring interval after the end of the main injection, the individual accumulator pressure (pE) is filtered within a time window, a local minimum value of the filtered individual accumulator pressure is interpreted as the end of a post-injection, and a mathematical function is used to calculate a virtual start of the post-injection.

摘要： A method is described for examining a solidifying and/or hardening material such as cement, concrete or the like, using ultrasound waves emitted by an ultrasound transmitter, which penetrate the solidifying and/or hardening material, are continuously measured and analyzed. During solidification and/or hardening of the material, the signal shapes of the ultrasound waves penetrating the material, are recorded. The change with time of the compression wave velocity and/or the relative energy of the ultrasound waves and/or the frequency spectra of the ultrasound waves is extracted from the ultrasound wave shapes during the entire course of solidification and/or hardening of the material. This change with time of the compression wave velocity and/or the relative energy of the ultrasound waves and/or the frequency spectra of the ultrasound waves is approximated through a compensating function, preferably the Boltzmann function. The free parameters of the compensation function are associated with material properties and permit comparison of a current measurement with reference values of these parameters to permit determination of material properties of the examined material. A receptacle and an ultrasound transmitter for carrying out the method also are described.

摘要： A method for detecting a preinjection in an internal combustion engine with a common-rail system, including individual accumulators, in which an individual accumulator pressure distribution is detected in a measurement interval and is used to determine an injection end of the main injection, in which a virtual injection start of the main injection is computed by a mathematical function as a function of the injection end, and in which the virtual injection start is set as the actual injection start of the main injection. With the preinjection activated, an actual injection delay for the main injection is determined as a function of the actual injection start, an injection delay deviation of a set injection delay from the actual injection delay is computed, and the injection delay deviation is used to determine whether a preinjection has occurred.
