摘要： A selective catalytic reduction system control system (10) and method of its use include an ammonia (“NH3”) slip sensor (13) located within an interior space (27) of an exhaust stack (15) of a selective catalytic reactor (31), toward an inlet end (25) of the stack (15); a housing (17) located within the interior space of the exhaust stack; the housing including face panels 19; a nitrogen oxides (“NOx”) sensor (11) contained within an interior space (29) defined by the face panels of the housing, at least two of the face panels (19I, 19O) containing an oxidation catalyst; and a dosing controller (59) in communication with the NH3 and NOx sensors, the dosing controller including a microprocessor with dosing logic embedded thereon. The housing with oxidation catalyst acts as a linear box, isolating the NOx sensor from NH3 slip, linearizing the NOx sensor signal.

摘要： A diesel engine emissions catalyst which may be used to fill a niche between standard oxidation catalyst and diesel particulate filters for control of diesel particulate matter. The catalyst includes a structure (substrate) comprising one or more coated, corrugated micro-expanded metal foil layers. The coated surface may be a high surface area, stabilized, and promoted washcoat layer. The corrugated pattern may include a herringbone-style pattern that, when in use, is oriented in a longitudinal direction of the diesel engine exhaust flow. The micro-expanded metal foil provides small openings or eyes that, as the exhaust flow passes through the catalyst (transverse to the eye opening), particulates in the flow impinge on the surface and becomes trapped in the eyes. The catalyst may be used to treat a locomotive engine exhaust stream and may be used with a selective catalyst reduction system.

摘要： A system and method for non-destructive testing of a monolith catalyst element includes a a piping arrangement located above and below the element that seals against a portion of the element. A test fluid passes between the piping and therefore through the portion of the sealed catalyst section. Ports located in the piping allow for sampling of the fluid before and after the catalyst section. The catalyst element may then be repositioned for testing of a second portion of the element.

摘要： A system and method for non-destructive testing of a monolith catalyst element includes an inlet and outlet piping arrangement seal against opposing face surfaces of the catalyst element and permit at least a portion of the catalyst element to be tested. A gap between the surface on which the catalyst element rests and the inlet piping prevents or reduces heat transfer between the piping and the surface. A test fluid passes between the piping and therefore through the portion of the sealed catalyst section. Ports located in the piping allow for sampling of the fluid before and after the catalyst section. The catalyst element may then be repositioned on the surface for testing of a second portion of the element. Alternatively, the catalyst element and its housing can be placed on a pivot table so the housed catalyst element can be tested.

摘要： An exhaust system includes a muffler, an inlet pipe, and an exhaust pipe. The muffler includes an inlet hole adapted to receive the inlet pipe and an outlet hole to receive the exhaust pipe. The inlet pipe has a first and second linear portions extending from a radiused portion, the first and second linear portions being generally perpendicular to one another. The radiused portion and the first linear portion of the inlet pipe are positioned within the muffler. Portions of the inlet pipe and exhaust pipe located within the muffler may optionally include perforations and be closed off.
