Patent number: 11467555Abstract: A method for determination of an effective machine use of a machine tool, as well as a machine tool that is configured for this purpose. The machine tool has multiple machine axes in order to move a workpiece and/or a tool. A rotary drive drives the workpiece or the tool in order to remove material. A control unit of the machine tool determines a use duration characteristic parameter (T) and an output power characteristic parameter (L) and determines therefrom a machine use characteristic parameter (M). The use duration characteristic parameter (T) describes a duration during which the workpiece is machined by the tool. The output power characteristic parameter (L) describes the applied or required power in order to effect the material removal. The machine use characteristic parameter (M) is determined by the control unit, such that it can be transmitted to an external unit for further evaluation or processing.Type: GrantFiled: February 14, 2020Date of Patent: October 11, 2022Assignee: GEBR.

Patent number: 10060377Abstract: A method for determining an imbalance of at least one cylinder in an arrangement of at least two cylinders in a system is provided, which includes an internal combustion engine, the imbalance of the at least one cylinder being present in relation to at least one property of an exhaust gas of the internal combustion engine and the determination of the imbalance of the at least one cylinder occurring with a sensor device for detecting at least one property of the exhaust gas of the internal combustion engine. A diagnostic threshold is ascertained through a dynamic characterization of the system with the sensor device, the dynamic characterization taking place after an excitation of the system. The diagnostic threshold makes it possible to delimit a range of potential erroneous detections which are caused due to a dispersion of an evaluating signal resulting from the imbalance of the at least one cylinder.Type: GrantFiled: May 6, 2015Date of Patent: August 28, 2018Assignee: Robert Bosch GMBHInventors: Klaus Winkler, Henrico Runge, Benjamin Sillmann, Hartwig Lehle, Eduard Weiss

Patent number: 8312709Abstract: An internal combustion engine is operated with direct fuel injection into the combustion chambers. Furthermore, the internal combustion engine is operated with sub-optimum ignition angle efficiency and an apportionment of a fuel quantity, which is to be injected before the start of a combustion, into at least two partial injections. A torque loss which results from the sub-optimum ignition angle efficiency and/or from the apportionment of the fuel to be injected is compensated by means of an increased charge of the combustion chambers. The fuel quantity and the charge are coordinated with one another in such a way that the air ratio lambda of the combustion chamber charges is greater than 1.Type: GrantFiled: December 27, 2007Date of Patent: November 20, 2012Assignee: Robert Bosch GmbHInventors: Norbert Mueller, Guido Porten, Juergen Raimann, Klaus Winkler

Publication number: 20060168943Abstract: A method for operating an internal combustion engine and a device for implementing the method may allow a catalytic converter diagnosis with a high degree of accuracy. At least one catalytic converter is positioned in the exhaust-gas region of the internal combustion engine, and a lambda sensor, which is configured as broadband lambda sensor, is positioned downstream from the catalytic converter or downstream from a section of the catalytic converter. The catalytic converter diagnosis is based on the evaluation of a measure for the oxygen storage capacity of the catalytic converter/within the catalytic converter. An at least approximately empty/filled oxygen reservoir of the catalytic converter is assumed. A change in the lambda setpoint value of the internal combustion engine to an excess air factor lambda that is greater than 1/less than 1 follows. Subsequently, a first change of the lambda signal is detected initially.Type: ApplicationFiled: January 18, 2006Publication date: August 3, 2006Inventors: Eberhard Schnaibel, Jens Wagner, Kersten Wehmeier, Klaus Winkler, Richard Hotzel

Patent number: 7051515Abstract: The invention further relates to a method and a model for modeling a discharge phase of a nitrogen oxide (NOx)-storage catalytic converter (12?) of an internal combustion engine (1). The NOx-storage catalytic converter (12?) is subdivision into an oxygen (O2)-store and a nitrogen oxide (NOx)-store and a reducing agent mass flow (msrg) is determined which charges the O2-store and the NOx-store. To model a discharge phase of the NOx-storage catalytic converter (12?), the O2-store is modeled via a first integrator for oxygen (O2) and the NOx-store via a second integrator for nitrogen oxide (NOx) and the first integrator and the second integrator are charge proportionally with the reducing agent mass flow (msrg) in accordance with an apportioning factor determined in dependence upon the O2-store content (mo2sp) and the NOx-store content (mnosp) of the NOx-storage catalytic converter (12?).Type: GrantFiled: July 20, 2001Date of Patent: May 30, 2006Assignee: Robert Bosch GmbHInventors: Eberhard Schnaibel, Klaus Winkler, Klaus Hirschmann

Patent number: 6901745Abstract: The invention relates to a method for operating a nitrogen oxide (NOx) storage catalytic converter (12?). During a first operating phase of the storage catalytic converter (12?), nitrogen oxides are stored and, during a second operating phase, stored nitrogen oxides are discharged from the converter (12?). The stored quantity of nitrogen oxides is determined during the first operating phase. In order to be able to determine start and end of the second operating phase as accurately as possible, a quantity, which characterizes the discharge quantity of nitrogen oxides, is determined during the second operating phase and compared to the stored quantity of nitrogen oxides determined during the first operating phase. With the comparison, a plausibility check and a calibration of the output signal of a nitrogen oxide (NOx) sensor (14?) can take place. The nitrogen oxide (NOx) sensor (14?) is disposed downstream of the storage catalytic converter (12?).Type: GrantFiled: July 11, 2001Date of Patent: June 7, 2005Assignee: Robert Bosch GmbHInventors: Eberhard Schnaibel, Klaus Winkler
