Abstract: Multi-electrode ablation systems, methods, and controllers are described. In one example, a multi-electrode ablation system generally includes a power supply and a controller. The power supply is configured to be coupled to a plurality of electrodes for delivering power to the electrodes. The controller is operable to compare a measured temperature at each electrode to a desired temperature to thereby define a temperature difference for each electrode. The controller is operable to determine, based on the temperature difference, a desired power for each electrode, compare the desired power of one of the electrodes to an actual power delivered to the one of the electrodes to define a power difference, and adjust the actual power delivered by the power supply to the one of the electrodes based on the power difference.

Abstract: A mixing system for an exhaust aftertreatment system includes a first mixing device having a plurality of first auger blades and an inlet having a first cross-sectional area. A second mixing device is separate and downstream from the first mixing device and includes a second auger blade. The second mixing device includes an inlet having a second cross-sectional area greater than the first cross-sectional area. A plurality of flow paths created by the first mixing device are recombined into a single flow path between the first and second mixing devices. A longitudinal center line of the first mixing device is offset from a longitudinal center line of the second mixing device.

Abstract: An exhaust aftertreatment system may include an exhaust gas passageway and a mixer assembly. The exhaust gas passageway may receive exhaust gas output from a combustion engine. The mixer assembly may be disposed along the exhaust gas passageway and may receive the exhaust gas. The mixer assembly may include a mixer housing, a mixing bowl and an injector housing. The mixing bowl may be disposed within the mixer housing and may include an outer diametrical surface that engages an inner diametrical surface of a wall of the mixer housing. The injector housing may extend through the wall and into an aperture in the mixing bowl. The aperture may define a flow path through which at least a majority of the exhaust gas entering the mixer assembly flows. The mixing bowl may include an upstream end portion having contours directing the exhaust gas toward the injector housing.
