Abstract: A system for coordinated control of an engine and associated components over various engine-modes of operation. The system may include an engine, one or more components controllable to adjust operation of the diesel engine, and a system controller. The system controller may be connected to the engine and the one or more components. The system controller may include a supervisory controller and one or more component controllers. The supervisory controller may receive system control variable set points and coordinate component control variable set points for the components to achieve the system control variable set points. The component controllers may control operation of the components to achieve the control variable set points for the components by setting manipulated variable set points for the components based on the component control variable set points and a model based non-linear dynamic inversion.

Abstract: A control apparatus for an engine includes a rotation detector, a fuel injection device, and an output controller. The output controller calculates an emission amount of the pollutant and calculates an accumulated emission amount of a pollutant for a period of time. The output controller calculates a maximum allowable emission amount of the pollutant for a period of time. The output controller calculates a difference between the accumulated emission amount of pollutant and the maximum allowable emission amount of the pollutant. The output controller calculates a first output index by dividing the difference by the period of time. The output controller sets the allowable range for the output of the engine so that the emission amount of pollutant becomes equal to or less than the first output index.

Abstract: A method includes operating a spark ignition engine and flowing low pressure exhaust gas recirculation (EGR) from an exhaust to an inlet of the spark ignition engine. The method includes interpreting a parameter affecting an operation of the spark ignition engine, and determining a knock index value in response to the parameter. The method further includes reducing a likelihood of engine knock in response to the knock index value exceeding a knock threshold value.
