    Abstract: An internal combustion engine includes an engine block, a combustion cylinder including a cylinder wall, engine oil and engine coolant. Control of the internal combustion engine includes estimating the cylinder wall temperature in a temperature state estimator, comparing the estimated cylinder wall temperature to a predetermined temperature threshold, and circulating the engine coolant in the engine when the estimated cylinder wall temperature exceeds the predetermined temperature threshold.

    Abstract: Systems and methods are provided for management of a thermal system. A system for thermal management includes a thermal system with fluid conduits. A sensor is disposed to monitor an input parameter state of the thermal system. An actuator is configured to vary a flow in the fluid conduits. A controller is configured to receive a signal representative of the input parameter state; process an actuator state through a flow model of the thermal system to obtain an existing flow in the fluid conduits; process the existing flow through a thermal model of the thermal system to determine an input that reduces an error between a desired parameter state and the input parameter state; process the input through an inverse flow model to convert the input to a desired actuator state; and position the actuator in the desired actuator state.

    Abstract: A method of estimating soot loading in a diesel particulate filter (DPF) in a vehicle exhaust system includes estimating an engine-out soot rate using a first neural network that has a first set of vehicle operating conditions as inputs. The method further includes estimating DPF soot loading using a second neural network that has the estimated engine-out soot rate from the first neural network and a second set of vehicle operating conditions as inputs. Estimating the engine-out soot rate and estimating the DPF soot loading are performed by an electronic controller that executes the first and the second neural networks. The method also provides for training the first and second neural networks both offline (for initial settings of the neural networks in the vehicle), and online (when the vehicle is being used by a vehicle operator). An exhaust system has a controller that implements the method.

    Abstract: An engine assembly includes an exhaust system having a first SCR catalyst, a second SCR catalyst in fluid communication with the first SCR catalyst, and an injector configured to inject reductant into the exhaust system. A controller is configured to estimate a first amount of ammonia stored in the first SCR catalyst and to estimate a second amount of ammonia stored in the second SCR catalyst. The controller is operatively connected to the injector and configured to control the amount of reductant injected by the injector. The controller controls the injector based on the first amount, the second amount, and a temperature of a substrate disposed in the second SCR catalyst.

    Abstract: An automotive vehicle includes an internal combustion engine that combusts an air/fuel mixture thereby generating exhaust gas containing particulate matter, and an exhaust after-treatment component that collects the particulate matter. A regeneration system burns off the collected particulate matter thereby regenerating the exhaust after-treatment component. A controller obtains a model of the combustion that is based on a kinetic controlled combustion phase and a mixing controlled combustion phase, and determines a point on the model with respect to current engine conditions that indicates an amount of the particulate matter in the exhaust gas.
