Patent number: 10774717Abstract: Various structures for catalytic convertors are disclosed herein. The device includes an outer housing enclosing a catalytic core. The catalytic core can be formed in a myriad of ways. Flow paths through the core are constructed so that they are not straight-line paths from the inlet of the device to the outlet of the device. Zigzag conformations and stacked panel arrays are described that maximize the catalytic surface area in a given volume of housing.Type: GrantFiled: October 27, 2018Date of Patent: September 15, 2020Assignee: Imagine TF, LLCInventor: Brian Edward Richardson

Patent number: 10774719Abstract: A side feed inlet port for an injector, which makes use of stamped parts to form a compact, high strength three-piece inlet port at a significantly reduced cost. By using an inner sleeve and an outer sleeve, injector sealing is accomplished using the interior sleeve, creating a sealing point, while allowing for inlet conduit attachment to the outer sleeve at, above, or below the sealing point of the DEF injector. The construction of the inlet port is such that there is proper sealing between the inner sleeve and one or more seals, while allowing for the connection between the inlet conduit and the outer sleeve to reduce the overall height of the inlet port, and therefore, the injector. The position of the inlet conduit may be altered without affecting the sealing connection between the inner sleeve and the seal(s), such that the desirable overall height may be achieved.Type: GrantFiled: August 18, 2016Date of Patent: September 15, 2020Assignee: Vitesco Technologies USA, LLC.Inventor: Robert Wayne McFarland

Patent number: 10774720Abstract: An exhaust aftertreatment system includes a first catalytic converter, an oxidation catalyst including a storage catalyst, an air injector, and a cooling unit. The exhaust aftertreatment system is fluidly coupled to an output of a spark-ignited internal combustion engine that operates in the rich regime during acceleration and the lean regime during deceleration. In one aspect, the storage catalyst stores ammonia produced while the engine operates in the rich regime. The stored ammonia reacts with nitrogen oxide compounds produced when the engine operates in the lean regime. In another aspect, the nitrogen oxide compounds react with ammonia produced while the engine operates in the rich regime.Type: GrantFiled: November 1, 2017Date of Patent: September 15, 2020Assignee: Tecogen, Inc.Inventors: Ahmed F. Ghoniem, Jean Roy

Patent number: 10774722Abstract: Particulate filters are used to remove particulate matter such as soot and ash in the emissions control systems of vehicles, including gasoline direct injection (GDI) engines. Methods are provided to predict the long-term performance and durability of emissions control systems having particulate filters. The methods account for factors such as thermal aging, soot accumulation and regeneration, and ash loading.Type: GrantFiled: September 4, 2018Date of Patent: September 15, 2020Assignee: Afton Chemical CorporationInventors: Huifang Shao, Joseph W. Roos, Joseph E. Remias

Patent number: 10774723Abstract: In a method and a device for diagnosing a differential pressure sensor of a particle filter of an internal combustion engine, where the differential pressure sensor is connected via a first pressure line to an exhaust-gas system upstream from the particle filter and via a second pressure line to the exhaust-gas system downstream from the particle filter and upstream from a rear muffler, a diagnosis of the first or second pressure lines is performed by evaluating a comparison of a differential pressure signal from a differential pressure sensor with modeled pressure values.Type: GrantFiled: June 27, 2018Date of Patent: September 15, 2020Assignee: Robert Bosch GmbHInventors: Martin Stephani, Martin Brandt, Yunjie Lian

Patent number: 10774724Abstract: An exhaust aftertreatment system includes a first stage catalytic converter, a second stage catalytic converter, and a conduit extending from the first stage catalytic converter to the second stage catalytic converter. The conduit passes through an exhaust gas intercooler, between the first and second stage catalytic converts, that reduces the temperature of the exhaust to about 300° F. to about 500° F. Air is ejected into the exhaust conduit to increase the oxygen concentration in the exhaust before it passes through the second stage catalytic converter. The air can be ejected from an air ejection conduit that extends to an engine charger compressor or a compressed air conduit that extends from the engine charger compressor, such as a turbo charger and/or a supercharger, to the engine. A gas particulate filter can be disposed in the exhaust conduit or it can be integrated with the second stage catalytic converter, for example as a catalyzed gas particulate filter.Type: GrantFiled: April 25, 2017Date of Patent: September 15, 2020Assignee: Tecogen, Inc.Inventors: Ahmed F. Ghoniem, Robert Panora, Jean Roy, Joseph Gehret

Patent number: 10774725Abstract: Methods and systems are provided for reducing temperature of an engine or single cylinder(s) of the engine at start/stop events where the engine is stopped from combusting air and fuel, and in response to an overheating engine condition. In one example, a method comprises activating an electric air compressor to direct cooling air flow through a first single cylinder of the engine, to reduce a temperature of the first single cylinder to a desired temperature prior to a request to restart the engine. In this way, a single cylinder indicated to be overheating may be effectively cooled, without employing methodology that would otherwise cool the engine as a whole, which may thus prevent engine degradation and which may conserve power of an onboard energy storage device.Type: GrantFiled: January 3, 2018Date of Patent: September 15, 2020Assignee: Ford Global Technologies, LLCInventor: Aed M.
