摘要： An engine assembly comprises an exhaust gas recirculation circuit, an aftertreatment apparatus and a controller. The controller is configured to determine a desired proportion of exhaust gas to be directed to the exhaust gas recirculation circuit. The controller is further configured to determine, based on the proportion of exhaust gas to be directed to the exhaust gas recirculation circuit, a baseline value for an extent to which to open the exhaust gas recirculation valve for a clean aftertreatment apparatus. The controller is further configured to determine a compensation function based on an inferred aftertreatment flow restriction value. The controller is further configured to control the extent to which the exhaust gas recirculation valve is open based on the baseline value modified by the compensation function in order to maintain the desired proportion of exhaust gas to be directed to the exhaust gas recirculation circuit.

摘要： A process for removing an existing core from a DECD housing may comprise the steps of providing a core press station having a working platform; connecting a collection container between the working platform and the DECD housing; aligning the DECD housing over the collection container; pressings the existing core out of the DECD housing; and collecting the existing core into the collection container. A process for inserting a replacement core into a DECD housing may comprise the steps of providing a core press station having a working platform; coupling a stuffing funnel to the DECD housing; wrapping the replacement core with a matting; aligning the replacement core with the DECD housing; and pressing the replacement core through the stuffing funnel and into the DECD housing.

摘要： An apparatus for protecting a component of an exhaust system using a hinged clamp. The clamp has grouped links that are joined by hinge pins that fit within apertures in the links and the grouped links are movable relative to each other about the hinges. A closer that draws the ends of selected links together is also disclosed.

摘要： An exhaust gas treatment apparatus includes a treatment cabinet and a catalyst part. To the treatment cabinet, introduced is exhaust gas of an engine which uses gas containing methane as a fuel. The catalyst part is accommodated in the treatment cabinet and oxidizes unburned methane contained in the exhaust gas. When a temperature of the catalyst part is lower than a predetermined normal operating temperature, the catalyst part oxidizes carbon monoxide contained in the exhaust gas and uses oxidation reaction heat of carbon monoxide, to thereby raise the temperature of the catalyst part up to the normal operating temperature or higher. Even when the temperature of the exhaust gas supplied to the catalyst part is lower than the normal operating temperature, it is thereby possible to quickly raise the temperature of the catalyst part up to the normal operating temperature por higher.

摘要： An exhaust treatment system includes an engine, an exhaust line in fluid communication with the engine, a three-way catalyst downstream of the engine on the exhaust line, a particulate filter downstream of and proximate to the three-way catalyst on the exhaust line, and a sorbent unit comprising a first sorbent and a second sorbent downstream of the three-way catalyst and the particulate filter on the exhaust line. The first sorbent and the second sorbent are proximate to a tailpipe of the exhaust line. A method of treating an exhaust emission from an internal combustion engine during an engine cold-start is also described.

摘要： A controller for a hydrogen engine controls a hydrogen engine including a selective catalytic reduction (SCR) device installed in an exhaust passage and a urea addition valve that adds urea to exhaust gas flowing through a portion of the exhaust passage upstream of the SCR device. Processing circuitry of the controller executes a reduction process that causes a urea addition amount of the urea addition valve to be smaller when a urea deposition amount of the SCR device is greater than or equal to a prescribed value than when the urea deposition amount is less than the prescribed value. The processing circuitry executes a lean-burn limiting process that sets an air-fuel ratio of an air-fuel mixture to be burned in the hydrogen engine to a value less than or equal to a prescribed lean-burn limiting value while the reduction process is reducing the urea addition amount.
