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.

Abstract:

A fuel control system for a vehicle comprises a fuel control module, a heat release determination module, and a detection module. The fuel control module supplies fuel to a cylinder of a diesel engine for combustion within the cylinder. The heat release determination module determines a heat release value based on a pressure within the cylinder during the combustion. The detection module selectively indicates that the fuel is a diesel fuel alternative when the heat release value is less than a predetermined heat release value. The predetermined heat release value is less than a second predetermined heat release value associated with diesel fuel.

International Classification:

F01N 3/025

US Classification:

60286, 60295

Abstract:

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.

F01N 3/035

US Classification:

60286, 60295, 60287, 60297

Abstract:

An engine control system includes an injection determination module, a correction factor determination module, and a regeneration control module. The injection determination module determines a desired amount of hydrocarbons (HC) to inject into exhaust gas produced by an engine based a flow rate of the exhaust gas. The correction factor determination module determines a correction factor for the desired amount of HC based on engine speed and engine load. The regeneration control module controls injection of an adjusted amount of HC into the exhaust gas during regeneration of a particulate matter filter, wherein the adjusted amount of HC is based on the desired amount of HC and the correction factor.

International Classification:

F01N 3/00
F02D 43/00

US Classification:

60274, 60285

Abstract:

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.

International Classification:

F01N 11/00

US Classification:

60277

Abstract:

An exhaust gas treatment system for an internal combustion engine for determining a total amount of sulfur that is stored on at least one aftertreatment device is provided. The exhaust gas treatment system includes a control module that monitors operation of the internal combustion engine for an amount of fuel consumed and an amount of oil consumed by the internal combustion engine. The control module includes a sulfur adsorption module and a total sulfur storage module. The sulfur adsorption module determines a rate of sulfur adsorption in at least one aftertreatment device. The rate of sulfur adsorption is based on the amount of fuel consumed and the amount of oil consumed. The total sulfur storage module is in communication with the sulfur adsorption module. The total sulfur storage module determines the total amount of sulfur stored based on the rate of sulfur adsorption.
