Abstract: An exhaust treatment system may include a burner, a flame sensor assembly and a control module. The flame sensor assembly may be at least partially disposed within the burner and may include an insulator and an electric heating element in heat transfer relation with the insulator. The control module may be in communication with the flame sensor assembly. The control module may determine whether a flame is present in a combustion chamber based on feedback from the flame sensor assembly. The control module may detect contamination on the insulator based on feedback from the flame sensor assembly. The control module may operate the heating element in a first mode in response to detection of a contamination in which the control module causes electrical power to be applied to the heating element to raise a temperature of the heating element to burn contamination off of the insulator.

Abstract: An exhaust aftertreatment system for an engine is provided that includes a burner, an air supply system and a control module. The air supply system may be in fluid communication with the burner and may include an air compressor disposed upstream from the burner. The air compressor may include a pump mechanism, a clutch assembly selectively transferring torque from the engine to the pump mechanism, and a motor selectively driving the pump mechanism. The control module may be in communication with the clutch assembly and the motor. The control module may selectively switch the air compressor between a first operating mode in which the clutch assembly transfers torque from the engine to the pump mechanism and a second operating mode in which the motor drives the pump mechanism.

Abstract: An exhaust aftertreatment system may include a first housing and a burner. The first housing may include first and second chambers. The first chamber may include an exhaust gas inlet receiving exhaust gas from an engine. The second chamber may receive exhaust gas from the first chamber and may include an exhaust gas outlet. The burner may include a second housing and a combustion chamber disposed within the second housing. The second housing may be at least partially disposed within the first chamber. The burner may supply heated gas to the second chamber. The heated gas within the burner may be fluidly isolated from exhaust gas in the first chamber. The second housing may be in a heat transfer relationship with exhaust gas in the first chamber.
