Abstract: A method of monitoring the reductant delivery performance of a selective catalytic reduction component of a vehicle exhaust system, includes operating a diesel exhaust fluid pump until a reductant delivery performance pressure setpoint is reached. Calculating an average pump duty cycle and commanding the calculated pump duty cycle to be used in the open loop control phase. Calculating an initial average pressure. Injecting a controlled diesel exhaust fluid (DEF). Calculating a final average pressure. Calculating a pressure drop ΔP and determining if the calculated pressure drop ΔP is less than an expected pressure drop calculated as a function of the average pump duty cycle.

Abstract: An exhaust gas treatment device includes a housing having a wall. The wall of the housing defines an interior chamber. A substrate is supported by the housing within the interior chamber of the housing. The substrate extends along a longitudinal axis. The substrate includes a flow through structure that allows the flow of exhaust gas to flow through the substrate. The substrate includes a catalytic composition disposed thereon for reacting with the flow of exhaust gas. The substrate includes a cavity, extending along a cavity axis, which is transverse to the longitudinal axis of the substrate. A sensor is attached to the housing. The sensor includes a probe that at least partially extends into the cavity of the substrate, for sensing a gaseous component in the flow of exhaust gas. The cavity mixes the flow of exhaust gas and directs the exhaust gas toward the probe of the sensor.

Abstract: An exhaust system for a lean-burn internal combustion engine is described, and includes an injection system for injecting reductant into an exhaust gas feedstream upstream of a selective catalytic reduction device (SCR). A control method for controlling the injection system includes determining an upstream NOx gas concentration upstream of the SCR device, determining a measured downstream NOx gas concentration based upon a signal output from a sensor configured to monitor NOx gas concentration downstream of the SCR device, and determining an estimated downstream NOx gas concentration based upon an executable model. A first correlation between the upstream NOx gas concentration and the measured downstream NOx gas concentration is determined, and a second correlation between the upstream NOx gas concentration and the estimated downstream NOx gas concentration is determined. The reductant injection is controlled based upon the first and second correlations.

Abstract: An exhaust gas treatment system includes a SCR device that stores a reductant that reacts with the NOx emissions and a reductant supply system to inject the reductant according to a reductant load model. At least one temperature sensor or model generates a temperature signal indicating an SCR temperature of the SCR device. The exhaust gas treatment system further includes a control module in electrical communication with the reductant supply system. The control module is configured to determine an amount of reductant that slips from the SCR device based on the at least one temperature signal and the rate of change of the SCR temperature. The control module further determines a correction factor based on the amount of slipped reductant to modify the reductant load model.

Abstract: A system including a flow straightener for a fuel cell cathode subsystem is provided. The system includes an intake manifold including a tube configured for providing an airflow to a compressor of the fuel cell cathode subsystem. The intake manifold includes an inlet configured for receiving the airflow into the intake manifold. The system further includes a mass air flow sensor disposed upon the intake manifold and a flow straightener disposed within the intake manifold between the inlet and the mass air flow sensor. The intake manifold includes an upstream portion between the flow straightener and the intake manifold inlet. The intake manifold further includes a downstream portion between the flow straightener and the mass air flow sensor. The flow straightener is configured for causing the airflow within the downstream portion to be less turbulent than the airflow within the upstream portion.

Abstract: A pressure-based latching switch includes a shuttle valve, a first valve and a second valve. The shuttle valve may switch a fuel through one of a first port and a second port in response to a greater pressure of the fuel at the ports. The first valve may switch a fuel to the first port while a second pressure of the fuel at the second port is less than a second threshold pressure. The second valve may switch the fuel to the second port while a first pressure of the fuel at the first port is less than a first threshold pressure. The pressure-based latching switch may change the fuel supplied to the fuel cell system automatically from a first fuel tank to a second fuel tank in response to the first pressure of the fuel falling below the first threshold pressure.

Abstract: A method for controlling an exhaust after-treatment system connected to a diesel engine via a gas passage and having a diesel oxidation catalyst (DOC) and a “diesel-exhaust-fluid” (DEF) injector arranged downstream of the DOC and upstream of a selective catalytic reduction catalyst (SCR) includes detecting a flow of exhaust gas emitted by the engine into the gas passage. The method also includes detecting a level of nitrogen oxides (NOx) in the exhaust gas downstream of the SCR. The method additionally includes activating the DEF injector for a period of time to reduce the level of NOx to a predetermined NOx value. Furthermore, the method includes regulating an injection of fuel upstream of the DOC to clean the DEF injector via a stream of superheated exhaust gas if the period of time used to reduce the level of NOx to the predetermined NOx value is greater than a predetermined threshold value.
