SYSTEMS AND METHODS FOR OPERATING PASSIVE NITROGEN OXIDE ADSORBERS IN EXHAUST AFTERTREATMENT SYSTEMS
Publication number: 20240151174Abstract: A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to: while controlling the bypass valve to direct exhaust gas to the PNA, detect a torque demand that is greater than a threshold value; responsive to detecting that the torque demand is greater than the threshold value, engage a motor, coupled with a battery system, with a drive shaft of the system to meet at least a portion of the torque demand; in response to the engagement of the motor with the drive shaft not meeting all of the torque demand, engage the engine with the drive shaft to meet a remainder of the torque demand.Type: ApplicationFiled: January 3, 2024Publication date: May 9, 2024Applicant: Cummins Inc.Inventors: Jinyong Luo, Xiaobo Song, Xing Jin, David Schmidt, Lu Qiu, Lisa A.

Publication number: 20240113319Abstract: A method includes providing steam to the solid oxide fuel cell stack, splitting exhaust gas from the cell stack into two portions, a first portion directed to a superheater and a second portion directed to an ejector and to a hydrogen separator. At least part of the first portion of the exhaust gas that is directed to the superheater is subsequently boiled in a boiler and then returned to the superheater. After being returned to the superheater, this part is directed to the ejector as high pressure steam so as to drive the ejector.Type: ApplicationFiled: September 29, 2023Publication date: April 4, 2024Inventors: John Robert PENDRAY, Achyut PAUDEL, Lars Krister HENRICHSEN, Enrique GARCIA-TORRESOLA, Jinyong LUO

Systems and methods for operating passive nitrogen oxide adsorbers in exhaust aftertreatment systems
Patent number: 11898483Abstract: A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to, determine that the catalyst is operating under cold start conditions, control the bypass valve to direct exhaust gas to the PNA, determine that the catalyst is no longer operating under cold start conditions and continue to control the bypass valve to direct exhaust gas to the PNA for a predetermined duration, and after the elapse of the predetermined duration, control the bypass valve to direct exhaust gas to the catalyst bypassing the PNA. The controller is also configured to detect a high transient torque demand while the exhaust gas is provided to the PNA, and split the torque demand between the engine and an electric motor.Type: GrantFiled: May 19, 2022Date of Patent: February 13, 2024Assignee: Cummins Inc.Inventors: Jinyong Luo, Xiaobo Song, Xing Jin, David Schmidt, Lu Qiu, Lisa A.

Publication number: 20220371575Abstract: A hybrid vehicle comprises an engine, an energy storage device, and an aftertreatment system comprising a SCR catalyst configured to treat constituents of an exhaust gas. A controller is operatively coupled to the engine, the energy storage device, and the after treatment system, and configured to estimate an exhaust gas temperature and flow rate of the exhaust gas based on a set of engine operating parameters. The controller determines an exhaust gas cooling rate based on the exhaust gas temperature, flow rate, and a SCR catalyst temperature, and an ambient cooling rate based on an ambient temperature, a vehicle speed and the catalyst temperature. The controller determines a SCR catalyst temperature change rate based on the exhaust gas and ambient cooling rates, and adjusts a load distribution between the engine and the energy storage device based on the SCR catalyst temperature change rate.Type: ApplicationFiled: August 31, 2020Publication date: November 24, 2022Applicant: Cummins Emission Solutions Inc.Inventors: Matthew K.
