摘要： An exhaust gas treatment system for an internal combustion engine is provided and includes an exhaust gas conduit, a hydrocarbon supply, a particulate filter (“PF”), at least one sensor, a first temperature sensor, a second temperature sensor, and a control module. The PF is in fluid communication with the exhaust gas conduit and has a filter structure for removal of particulates in the exhaust gas. The filter structure has an innermost region and an outermost region. The PF is selectively regenerated during operation of the internal combustion engine. The PF has a stratified temperature structure that causes the particulates trapped at the innermost region of the PF burn off before the particulates trapped in the outermost region of the PF during regeneration. The control module has a memory with an infinite stage temperature control curve stored thereon.

摘要： A control module for a vehicle includes a correction module that generates a correction signal based on a regeneration state of an exhaust system of the vehicle and based on a received environmental signal. The environmental signal includes at least one of an altitude value, an ambient temperature, and an air flow value. The air flow value corresponds to air flow across an external area of the exhaust system. A first post injection module generates a first post injection signal. A second post injection module adjusts the first post injection signal based on the correction signal to generate a second post injection signal.

摘要： An internal combustion engine includes an intake air compressor system and is fluidly coupled to an exhaust aftertreatment system having a particulate filter. A method for operating the internal combustion engine includes determining a total engine-out soot generation based upon a summation of a steady-state engine-out soot generation rate and an engine-out soot generation rate correction. The engine-out soot generation rate correction is either zero when the intake air compressor system is closed-loop controlled or a rate based upon a deviation between an actual boost pressure and an expected boost pressure from the intake air compressor system. The particulate filter is regenerated when the total engine-out soot generation exceeds a predetermined threshold.

摘要： A method unloads hydrocarbon emissions deposited by an exhaust gas on an after-treatment device that is employed in an exhaust system for an internal combustion engine. The method includes determining whether the engine has been operating at a preset idle speed for a predetermined amount of time. The method also includes increasing the preset idle speed by a predetermined value if the engine has been operating at a preset idle speed for a predetermined amount of time. The increasing of the engine idle speed increases a flow rate of the exhaust gas to the after-treatment device and unloads the deposited hydrocarbon emissions. A system for unloading hydrocarbon emissions deposited on an after-treatment device and a vehicle employing such a system are also disclosed.
