Abstract: A method for controlling a selective catalytic reduction device in an exhaust aftertreatment system of a vehicle includes monitoring vehicle connectivity information, and controlling ammonia storage in the selective catalytic reduction device based on the monitored vehicle connectivity information. Vehicle connectivity information is used to predict vehicle operating conditions along an estimated path of vehicle travel. The predicted vehicle operating conditions are used to predict profiles for vehicle exhaust gas parameters. Predicted profiles for exhaust gas parameters are used in determining ammonia storage setpoints for the selective catalytic reduction device. The ammonia storage setpoints are use in regulating an amount of ammonia producing dosing agent injected into the exhaust aftertreatment system, thereby controlling ammonia storage in the selective catalytic reduction device.

Abstract: A method of estimating a current soot output from an engine includes sensing a mass flow rate of a flow of exhaust gas from the engine, and defining a soot output base rate of the engine when the engine is operating at a reference state. A soot ratio for a current operating state of the engine is calculated. The mass flow rate, the soot output base rate, and the soot ratio are multiplied together to define an estimated value of the current soot output from the engine. The soot ratio is based on current engine operating parameters, including an air/fuel ratio of the engine, an exhaust gas recirculation ratio of the engine, a fuel injection pressure of the engine, and a fuel injection timing of the engine.

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: A method of estimating hydrocarbon storage in a catalytic device of an exhaust gas treatment system includes calculating an amount of hydrocarbons absorbed in the catalytic device per unit volume of exhaust gas over a period of time, calculating an amount of hydrocarbons desorbed in the catalytic device per unit volume of exhaust gas over the period of time, and calculating an amount of hydrocarbons oxidized in the catalytic device per unit volume of exhaust gas over the period of time. The amount of hydrocarbons oxidized in the catalytic device and the amount of hydrocarbons desorbed in the catalytic device are subtracted from the amount of hydrocarbons absorbed in the catalytic device to determine the amount of hydrocarbons stored in the catalytic device.

Abstract: A method of estimating a mass flow rate of nitrogen oxides in exhaust gas includes sensing a mass flow rate of a flow of exhaust gas from the engine. A nitrogen oxides base concentration for when the engine is operating at a reference state is defined, and a nitrogen oxides ratio for a current operating state of the internal combustion engine is calculated. The mass flow rate of the flow of exhaust gas, the nitrogen oxides base concentration, and the nitrogen oxides ratio for the current operating state of the engine are multiplied together to define an estimated value of the current mass flow rate of nitrogen oxides in the flow of exhaust gas from the engine. The estimated value of the mass flow rate of nitrogen oxides may be compared to the output from a nitrogen oxides sensor to determine proper functionality of the nitrogen oxides sensor.

Abstract: A system according to the present disclosure includes a model predictive control (MPC) module and an actuator module. The MPC module generates a set of possible target values for an actuator of an engine and predicts an operating parameter for the set of possible target values. The predicted operating parameter includes an emission level and/or an operating parameter of an exhaust system. The MPC module determines a cost for the set of possible target values and selects the set of possible target values from multiple sets of possible target values based on the cost. The MPC module determines whether the predicted operating parameter for the selected set satisfies a constraint and sets target values to the possible target values of the selected set when the predicted operating parameter satisfies the constraint. The actuator module controls an actuator of an engine based on at least one of the target values.

A heat release module, based on the value, determines an amount of heat released during a combustion event of the cylinder. A pressure module, based on the amount of heat released, estimates a pressure in the cylinder. A temperature module, based on the pressure, estimates a temperature in the cylinder. A concentration module, based on the pressure or the temperature, estimates nitrogen oxide concentration levels in the cylinder. An output module, based on the nitrogen oxide concentration levels, estimates an amount of nitrogen oxides. A control module, based on the amount of nitrogen oxides out of the cylinder, controls operation of the engine or an exhaust system.
