Electrically heated particulate filter heater insulation |
摘要 |
A system includes a particulate matter (PM) filter that includes an upstream end for receiving exhaust gas and a downstream end. A zoned resistive heater is arranged spaced from said upstream end and includes N zones, where N is an integer greater than one, wherein each of the N zones includes M sub-zones, where M is an integer greater than or equal to one, and wherein the zoned heater includes an electrically insulating material. A control module selectively activates at least a selected one of the N zones to initiate regeneration in downstream portions of the PM filter from the one of the N zones and deactivates non-selected ones of the N zones. |
