International Classification:

F01N 3/00

US Classification:

60295, 60297, 60276

Abstract:

A system comprises an injection control module and a fuel film module. The injection control module controls a flow rate of fuel injected into an exhaust system to adjust a temperature of exhaust gas. The fuel film module determines an accumulation rate of fuel on a surface of the exhaust system based on the flow rate of the fuel. The fuel film module determines a release rate of fuel from the surface of the exhaust system based on a flow rate of the exhaust gas. The injection control module adjusts the flow rate of the fuel based on the accumulation rate and the release rate.

US Classification:

60286, 60295, 60299, 60300, 60311

Abstract:

A temperature control system comprises a temperature determination module, a temperature correction module, a temperature control module, and an updating module. The temperature determination module determines a desired outlet temperature for an oxidation catalyst (OC) that is located upstream of a particulate filter (PF) in an exhaust system. The temperature correction module determines a temperature correction from a plurality of temperature corrections. The temperature control module controls an outlet temperature of the OC based on the desired outlet temperature and the temperature correction. The updating module selectively updates at least one of the plurality of temperature corrections when an engine speed and an engine load are within respective predetermined ranges.

US Classification:

60286, 60274, 60287, 60295, 60297, 60298, 60301, 60303, 60311

Abstract:

A dosing control system for a vehicle includes a pump control module and an enabling/disabling module. The pump control module controls a pump that provides dosing agent to a dosing agent injector located upstream of a selective catalytic reduction (SCR) catalyst in an exhaust system. The enabling/disabling module disables the pump for a predetermined melting period after engine startup when the dosing agent is frozen and selectively activates the pump during the predetermined melting period to cool the dosing agent injector when a tip temperature of the dosing agent injector is greater than a predetermined temperature.

Abstract:

A regeneration control system for a vehicle includes a regeneration control module and a regeneration interrupt module. The regeneration control module selectively provides fuel to an oxidation catalyst for a regeneration event of a particulate filter that occurs during a predetermined melting period for frozen dosing agent. The regeneration interrupt module selectively interrupts the regeneration event and disables the provision of fuel to the oxidation catalyst before the regeneration event is complete when a temperature of a dosing agent injector that is located between the oxidation catalyst and the particulate filter is greater than a predetermined temperature.

Abstract:

A dosing control system for a vehicle includes an adaption triggering module, a dosing management module, and an adaption ending module. The adaptation triggering module triggers performance of an adaptation event when a first amount of nitrogen oxides (NOx) measured by a first NOx sensor located downstream of a selective catalytic reduction (SCR) catalyst is greater than a predicted value of the first amount of NOx. The dosing management module disables dosing agent injection during the adaptation event. The adaptation ending module selectively delays ending the adaptation event after a predetermined number of phases of the adaption event have been completed based on a comparison of the first amount of NOx with a second amount of NOx measured by a second NOx sensor located upstream of the SCR catalyst.

Abstract:

An engine control system comprises an oxygen comparison module and a regeneration control module. The oxygen comparison module compares an oxygen concentration of an exhaust gas of an engine to an oxygen threshold. A regeneration control module initiates regeneration of a particulate filter and controls regeneration based on the oxygen comparison and at least one of a particulate filter load, a particulate filter temperature, and a speed of the engine.

US Classification:

423210, 423235, 423238, 4232391

Abstract:

A dosing control system for a vehicle includes a current storage module, an adaption triggering module, and an adaption ending module. The current storage module estimates an amount of ammonia stored by a selective catalytic reduction (SCR) catalyst. The adaptation triggering module triggers a reduction of the amount of ammonia stored by the SCR catalyst to zero when a first amount of nitrogen oxides (NOx) measured by a first NOx sensor located downstream of the SCR catalyst is greater than a predicted value of the first amount of NOx. The adaptation ending module selectively ends the reduction and enables injection of dosing agent based on a comparison of the first amount of NOx with a second amount of NOx upstream of the SCR catalyst.
