摘要： A system includes an internal combustion engine, an exhaust conduit fluidly coupled to the internal combustion engine and an SCR catalyst, and a reductant doser operationally coupled to the exhaust conduit at a position upstream of the SCR catalyst. The reductant doser is responsive to a reductant doser command. The system includes a controller having a number of modules functionally structured to execute operations to compensate for transient operation of the system. An NH3 target module interprets a reductant amount target that is a target amount of reductant in the exhaust conduit at a position upstream of the SCR catalyst. A transient adjustment module detects a transient event in the SCR catalyst and provides an adjusted reductant amount target in response to the transient event and the reductant amount target. A dosing control module provides the reductant doser command in response to the adjusted reductant amount target.

摘要： A system includes an engine, an exhaust conduit for the engine, a first SCR catalyst fluidly coupled to the exhaust conduit, and a second SCR catalyst fluidly coupled to the exhaust conduit at a position downstream of the first SCR catalyst. The system further includes an ammonia sensor positioned between the first and second SCR catalysts. A reductant doser is positioned upstream of the first SCR catalyst. The system includes a controller that determines an amount of NH3 present from the NH3 sensor, and computes an actuator response function from at least one operating condition of the first SCR catalyst. The actuator response function includes a reductant injector response as a function of the amount of NH3, and the actuator response function includes a response discontinuity. The controller further determines a reductant injection amount from the amount of NH3 and the actuator response function, and provides a reductant injector command.

摘要： A rigid metal housing is positioned downstream of a coating applicator. The housing supports a plurality of positionable contact elements formed of a low friction, high wear-resistant material, which extend inwardly from the housing to engage a slow speed rotating rod. At least one of the contact elements is adjustable to support the rod for stable rotation, and to retain an effective seal between the contact elements and the rod to thereby prevent leakage of clearing/lubricating fluid into the applied coating. The contact elements may be advanced inwardly as the elements and the rod wear, thereby extending the effective life of the rod holder apparatus. Screws may bear against a rear contact element through segmented backing plates allowing refinement of the coat weight along the width of the substrate. Furthermore, an air tube may be positioned between the housing and a rear fixture to adjust overall coating thickness.

摘要： A method for controlling charge flow in an internal combustion engine includes operating an engine having a VGT. The method includes determining a target and current charge flow and EGR flow. The method further includes determining an error term for the charge flow and the EGR flow, and determining an exhaust pressure feedback command in response to the error terms. The exhaust pressure feedback command is combined with an exhaust pressure feedforward command, and the VGT is controlled in response to the exhaust pressure feedback command. The method additionally includes determining the exhaust pressure feedback command in response to a current EGR valve position. The method further includes controlling an EGR flow rate with the EGR valve at relatively closed EGR valve positions, and controlling the EGR flow rate with exhaust pressure at relatively open EGR valve positions.
