    Abstract: A method of treating an exhaust gas produced by a vehicle internal combustion engine includes conveying the gas through a first reactor including a non-thermal plasma. The gas includes nitric oxide and is transitionable between a first condition in which the gas has a cold-start temperature that is less than or equal to about 150° C., and a second condition in which the gas has an operating temperature that is greater than about 150° C. During the first condition, the method includes contacting the gas and plasma to oxidize the nitric oxide to nitrogen dioxide and form an effluent that includes nitrogen dioxide. The method includes concurrently conveying the effluent through a second reactor including a diesel oxidation catalyst, and storing the nitrogen dioxide within the second reactor during only the first condition. The method includes, after storing, releasing nitrogen dioxide from the second reactor during only the second condition.

    Abstract: In one embodiment, a method for controlling nitrogen oxides in an exhaust gas received by an exhaust system, the exhaust system including a first selective catalytic reduction device, an exhaust gas heat recovery device and a second selective catalytic reduction device is provided. The method includes flowing the exhaust gas from an internal combustion engine into the first selective catalytic reduction device, receiving the exhaust gas from the first selective catalytic reduction device into the exhaust gas heat recovery device and directing the exhaust gas to a heat exchanger in the exhaust gas heat recovery device based on a temperature of the internal combustion engine proximate moving engine components. The method includes adsorbing nitrogen oxides from the exhaust gas via a nitrogen oxide adsorbing catalyst disposed in the heat exchanger and flowing the exhaust gas from the exhaust gas heat recovery device into the second selective catalytic reduction device.

    Abstract: A strategy for controlling an electric pump and control valve in an internal combustion engine cooling system compensates for backpressure variations and maintains system operation within design parameters. The method comprises the steps of measuring the coolant temperature, measuring the electrical current and voltage to the pump motor, determining the pump speed and coolant flow, determining the desired coolant flow, determining a negative correction to the flow control valve and pump if desired flow is less than present coolant flow and determining a positive correction to the flow control valve and pump if desired flow is more than present coolant flow and undertaking this correction to coolant flow. Thus, based upon inferred back pressure in the engine coolant system from the data relating to the pump energy input, proper coolant flow, heat rejection and engine operating temperature can be maintained in spite of variations in system flow restrictions and backpressure.

    Abstract: A method for implementing particulate filter regeneration management is provided. The method includes determining a presumptive deviation between a particulate model and actual particulate level conditions of the particulate filter. The presumptive deviation is determined from identification of an occurrence of extended parking, a passive regeneration, residual particulates, and a pressure signal. Each of the extended parking, passive regeneration, residual particulate, and pressure signal is specified by a respective particulate model deviation type. The method also includes selectively controlling current to at least one zone of a plurality of zones of an electric heater to initiate a regeneration event based on the presumptive deviation, and estimating the particulate level in the particulate filter once the regeneration event is complete.
