Patent number: 10746248Abstract: A valve assembly includes a first valve plate defining at least one first opening and at least one second opening. A valve element located above the first valve plate has a central portion, and at least one tab extending outwards from the central portion. The at least one tab includes a narrow portion axially aligned with the at least one first opening such that the narrow portion at least partially covers the at least one first opening. The at least one tab is selectively provided with electrical energy to melt the narrow portion to form an orifice. The orifice is fluidly coupled with the at least one first opening.Type: GrantFiled: July 25, 2018Date of Patent: August 18, 2020Assignee: Tenneco Automotive Operating Company Inc.Inventor: Perry Paielli

Patent number: 10648385Abstract: A DEF injector is configured to inject DEF into an exhaust system of a vehicle. A DEF pump includes an electric motor configured to drive a compression mechanism and pumps the DEF to the DEF injector. A pressure sensor is configured to measure a pressure of the DEF output from the DEF pump. A sampling module is configured to, based on a rotational position of an output shaft of the electric motor, selectively output samples of the pressure. A measurement module is configured to determine a measured pressure at the pressure sensor based on a present one of the samples and a last one of the samples output before the present one of the samples. A pump control module is configured to apply power from a power source to the electric motor based on a difference between the measured pressure and a target pressure.Type: GrantFiled: February 7, 2018Date of Patent: May 12, 2020Assignee: Tenneco Automotive Operating Company Inc.Inventor: Perry Paielli

Patent number: 10590823Abstract: An exhaust aftertreatment system includes a pump configured to circulate a reagent, an injector configured to deliver the reagent into an exhaust stream, a sensor configured to (i) measure an operating parameter of the aftertreatment system and (ii) output a signal that indicates a value of the measured operating parameter, and a control module configured to control the injector based on the signal outputted by the sensor. The control module includes a correction coefficient determination module configured to generate a correction coefficient based on the signal outputted by the sensor. The control module further includes an injector control module configured to receive an injector flow control signal, determine a pulse width modulation (PWM) signal based on at least the injector flow control signal, and generate an injector control signal that controls actuation of the injector based on at least the correction coefficient and the PWM signal.Type: GrantFiled: January 24, 2018Date of Patent: March 17, 2020Assignee: Tenneco Automotive Operating Company Inc.Inventor: Perry Paielli

Patent number: 10473015Abstract: A pressure sensor includes: a housing; a substrate that is fixed within the housing, that includes a first side that is in contact with a fluid of an exhaust aftertreatment system, and that flexes based on a pressure of the fluid; a first voltage divider that is connected between a first reference potential and a ground potential and that varies a first potential based on flexing of the substrate; and a second voltage divider connected in parallel with the first voltage divider between the first reference potential and the ground potential and that varies a second potential based on flexing of the substrate. A pressure control module is configured to selectively switch switches to connect and disconnect different reference potentials to and from an amplifier, to sample an output of the amplifier, and to convert samples of the output of the amplifier into corresponding digital values.Type: GrantFiled: October 9, 2017Date of Patent: November 12, 2019Assignee: Tenneco Automotive Operating Company Inc.Inventor: Perry Paielli

Patent number: 8234045Abstract: Systems and methods for mitigating failure mode effects in a steer-by-wire system. The system includes a controller configured to alter a direction of the vehicle when the controller is in a failure mode. A steering device is coupled to a detector. The detector is configured to detect a steering input from a driver and output a signal representative of the steering input. A first actuator is coupled to a first control device. The first control device is configured to generate a first control signal representative of the steering input when the controller is in the failure mode. The first actuator alters the direction of the vehicle by removing energy from the vehicle. A second actuator is coupled to a second control device. The second control device is configured to generate a second control signal representative of the steering input when the controller is in the failure mode. The second actuator alters the direction of the vehicle by adding energy to the vehicle.Type: GrantFiled: September 24, 2008Date of Patent: July 31, 2012Assignee: Robert Bosch GmbHInventors: William Spadafora, David Llewellyn, Perry Paielli, Jason Kramer
