Patent number: 10054019Abstract: A method and apparatus are disclosed for controlling the operation of an aftertreatment system for a motor vehicle having a Lean NOx Trap and a tail pipe for conveying exhaust gasses from the LNT to the external environment. Values are calculated for a NOx content in the exhaust gasses flowing in the tail pipe and the quantity of NOx stored in the LNT. A DeNOx request index is calculated as a function of these values. A raw threshold value of the DeNOx request index is calculated as a function of a LNT temperature and of an exhaust gas mass flow. A corrected threshold value of the DeNOx request index is calculated as a function of the raw threshold value of the DeNOx request index and of a correction factor. A DeNOx regeneration is initiated when the calculated value of the DeNOx request index is larger than the corrected threshold value.Type: GrantFiled: January 23, 2017Date of Patent: August 21, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Giacomo Latrofa, Giovanni Montinaro, Fabrizio Ramolivo, Luisa Cusanno, Matteo Venturini, Barbara Maisola

Patent number: 10054020Abstract: During execution of a first purification process of fluctuating a hydrocarbon concentration in exhaust gas flowing into a first catalyst with an amplitude within a prescribed range at a time interval within a prescribed range, when a switch request to a second purification process of purifying NOx in a second catalyst by adding urea water into the exhaust gas is generated, the switch to the second purification process is prohibited on the condition that a current NOx purification rate (a first purification rate R1) is higher than a purification rate (a second purification rate R2) on the assumption that the second purification process is executed, and an HC poisoning recovery stand-by process of reducing an additive amount of hydrocarbon per once in the first purification process is executed so as to reduce a slip amount of hydrocarbon into the downstream of the first catalyst.Type: GrantFiled: March 31, 2017Date of Patent: August 21, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Kohei Yoshida

Patent number: 10054021Abstract: In accordance with one aspect of the present disclosure, an accumulator is provided for an engine exhaust treatment system. The accumulator includes a container, an inlet portion for receiving exhaust treatment fluid, a conduit in communication with the inlet portion of the container to withdraw exhaust treatment fluid from the inlet portion, and an outlet portion configured to receive exhaust treatment fluid from the inlet portion and having an outlet for discharging exhaust treatment fluid. The accumulator includes a weir separating the inlet portion and the outlet portion that permits exhaust treatment fluid in the inlet portion to flow into the outlet portion.Type: GrantFiled: March 1, 2016Date of Patent: August 21, 2018Assignee: Caterpillar Inc.Inventor: Jason W. Hudgens

Patent number: 10054022Abstract: An exhaust after-treatment system for treating an exhaust produced by an engine. The exhaust after-treatment system includes an exhaust passage, at least one catalytic exhaust after-treatment component in communication with the exhaust passage for treating the exhaust, and a water-removal device in communication with the exhaust passage that receives a portion of the exhaust therein at a location positioned upstream from the catalytic exhaust after-treatment component. The water-removal device is defined by a housing that includes a water-removal membrane that separates water from the portion of the exhaust to provide a permeate that is enriched with water, and to produce a retentate that is water depleted that facilitates the treating of the exhaust by the catalytic exhaust after-treatment component.Type: GrantFiled: February 23, 2016Date of Patent: August 21, 2018Assignee: Tenneco Automotive Operating Company Inc.Inventor: Michael C.

Patent number: 10054026Abstract: There is provided an exhaust heat recovery structure that may suppress boiling of coolant in a heat exchanger. The exhaust heat recovery structure includes a first pipe, a second pipe, a valve and a thermostat. Exhaust gas from an engine flows in the first pipe. The second pipe branches from the first pipe and a heat exchanger that exchanges heat between the coolant and exhaust gas is provided at the second pipe. The valve is provided at the first pipe or the second pipe. The valve adjusts a flow amount of exhaust gas flowing into the second pipe by opening and closing. The thermostat is equipped with a heat-sensing portion that is disposed inside the heat exchanger. When the temperature of the heat-sensing portion is high, the thermostat opens or closes the valve to reduce the flow amount of exhaust gas flowing into the second pipe.Type: GrantFiled: May 10, 2016Date of Patent: August 21, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshio Murata, Tadashi Nakagawa
