International Classification:
F02D 41/30
US Classification:
701112, 123676, 60285
Abstract:
A control module comprises a thermal detection module and a protection module. The thermal detection module receives temperature data of a particulate matter filter and determines a temperature based on the temperature data. The protection module selectively reduces output of an engine when the temperature is greater than a temperature threshold. A method comprises receiving temperature data of a particulate matter filter and selectively reducing output of an engine when a temperature based on the temperature data is greater than a temperature threshold.
Regeneration Systems And Methods For Particulate Filters Using Virtual Brick Temperature Sensors

International Classification:
F01N 3/00
US Classification:
60295, 60274, 60277, 60286, 60299
Abstract:
An exhaust control system includes a temperature sensor, a temperature estimation module, and an exhaust condition adjustment module. The temperature sensor measures an outlet temperature of an exhaust gas downstream from an emission reduction device. The temperature estimation module estimates a highest temperature of the emission reduction device. The exhaust condition adjustment module controls operation of the exhaust control system based on the highest temperature of the emission reduction device.
Particulate Filter Temperature Correction System And Method

International Classification:
F01N 3/00
US Classification:
60285, 60274, 60297, 60311
Abstract:
A method and system of controlling an engine includes a control system includes an exhaust gas flow rate module generating an exhaust gas flow rate signal corresponding to a flow rate of exhaust gases. The control system further includes a temperature adjustment module that determines a temperature correction factor based on the exhaust gas flow rate and that determines a corrected temperature particulate sensor signal in response to a measured particulate temperature signal and the temperature correction factor.

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.
Particulate Filter Regeneration Interruption Systems And Methods
Jason Daniel Mullins - Howell MI, US Paul Jasinkiewicz - Northville MI, US Kyle E. Crawford - Howell MI, US Justin A. Shetney - Livonia MI, US Rebecca J. Darr - Milford MI, US
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.
System And Method For Establishing A Mass Flow Rate Of Air Entering An Engine

Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
G01M 15/04
US Classification:
7311432
Abstract:
A method of establishing a mass flow rate of air entering an engine includes establishing an input voltage by an energy supply device to energize a mass-air-flow sensor. The method also includes generating an output frequency via the mass-air-flow sensor in response to the mass flow rate of air entering the engine and determining the flow rate using the generated output frequency. The method additionally includes comparing the generated output frequency with a predetermined threshold output frequency that corresponds to the established input voltage. Additionally, the method includes selecting the determined flow rate as the established flow rate if the generated output frequency is at or below the predetermined threshold output frequency. Furthermore, the method includes selecting a predetermined alternative algorithm to generate the established flow rate if the generated output frequency is above the predetermined threshold output frequency. A system for establishing the mass flow rate is also provided.
Selective Catalytic Reduction (Scr) Catalyst Depletion Control Systems And Methods

International Classification:
F01N 3/20 F01N 3/10
US Classification:
60285, 60274, 60277, 60286, 60295, 60301, 60303
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:
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.
