Patent number: 10866207Abstract: An exhaust gas sensor for detecting a measurement gas component, having a ceramic sensor element fixed in a housing, and a double-walled protective pipe having outer and inner protective sleeves, the inner sleeve enclosing a gas chamber into which the sensor element extends with a segment at the measurement gas side, in the direction of a longitudinal axis of the sensor, and an annular chamber being formed between the outer and inner protective sleeves. The outer sleeve has a cladding surface having at least one opening configured as a swirling element, through which measurement gas can move into the annular chamber with rotation about a longitudinal axis of the sensor, and the inner sleeve has at least one opening that is adjusted and/or functionally optimized, as to a sensitive region of the sensor element, through which opening the measurement gas can move from the annular chamber into the gas chamber.Type: GrantFiled: November 15, 2016Date of Patent: December 15, 2020Assignee: Robert Bosch GmbHInventors: Johannes Weber, Benjamin Sillmann, Christoph Gmelin, Christopher Holzknecht, Karel Vacha, Katerina Lieblova, Milan Kotynek, Rafael Gitzmann, Sebastian Schulte Am Huelse, Simon Rentschler, Stefan Buehler

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: 9347903Abstract: Methods for detecting the type of lambda probes having at least two electrodes disposed on and/or in a solid electrolyte, of which at least one electrode is separated from a gas mixture by a diffusion barrier, and a pump current Ip being applied to at least one of the electrodes. Either the internal resistance of the lambda probe between the electrodes is determined and the type of probe is inferred on the basis of this resistance, or currents are impressed between the electrodes and the type of probe is inferred based on the voltages or resistance ratios thereby resulting.Type: GrantFiled: May 18, 2011Date of Patent: May 24, 2016Assignee: ROBERT BOSCH GMBHInventors: Claudius Bevot, Rolf Reischl, Thomas Classen, Benjamin Sillmann

Patent number: 9222911Abstract: A method for detecting at least one property of a gas in a measuring gas chamber, in particular for detecting at least one gas component of the gas. The at least one property is determined using at least one electrochemical measuring cell of a sensor element. Temperatures are detected at at least two different locations of the sensor element and used in determining the at least one property.Type: GrantFiled: July 20, 2011Date of Patent: December 29, 2015Assignee: ROBERT BOSCH GMBHInventors: Dirk Liemersdorf, Benjamin Sillmann

Patent number: 8940144Abstract: A sensor element of a gas sensor for determining gas components in gas mixtures, having at least one electrochemical measuring cell which is formed by a ceramic substrate and electrodes placed thereon. The sensor element includes at least one interior chamber which is sealed in a gas-tight manner, in which at least one first internal electrode is positioned, which forms an electrochemical cell with each of a second and an additional electrode of the sensor element, one of the electrochemical cells being an electrochemical pump cell, and the second or other electrode being exposed to the measuring gas.Type: GrantFiled: June 25, 2009Date of Patent: January 27, 2015Assignee: Robert Bosch GmbHInventors: Dirk Liemersdorf, Thomas Classen, Benjamin Sillmann

Patent number: 8858779Abstract: A method for detecting a proportion of at least one gas species in a measurement gas space. A sensor element is used, having an oxygen reduction pumping cell for concentration of the gas species, a pumping cell connected downstream of the oxygen reduction pumping cell having pumping electrodes, and a gas-tight chamber. A pumping electrode may be exposed to gas from the measurement gas space which has been concentrated by the oxygen reduction pumping cell. A further pumping electrode is disposed in the gas-tight chamber. At least one measuring electrode is further disposed in the gas-tight chamber. The oxygen reduction pumping cell and the pumping cell are galvanically isolated. The method includes an initialization phase, and an accumulation phase.Type: GrantFiled: October 21, 2010Date of Patent: October 14, 2014Assignee: Robert Bosch GmbHInventors: Dirk Liemersdorf, Benjamin Sillmann, Berndt Cramer
