Patent ID: 8104270

Claim:
A control system that controls regeneration of a particulate filter, comprising: a regeneration module that selectively indicates that regeneration of the particulate filter is needed; a fuel control module that delivers unburned fuel to the particulate filter in response to the regeneration module indicating that regeneration is needed and that selectively indicates that the delivery of unburned fuel to the particulate filter is complete, wherein the regeneration module controls current to a heater to initiate the regeneration in response to the fuel control module indicating that the delivery of unburned fuel to the particulate filter is complete; and a temperature control module that controls a temperature of the exhaust based on a temperature of combustion of particulate matter in the particulate filter during the regeneration and that estimates the temperature of the combustion of the particulate matter based on a flow of the exhaust, the temperature of the exhaust, a level of oxygen in the exhaust, and a temperature of the particulate filter.
