Abstract: Control of a turbocharger of a power system is disclosed. A controller may receive a desired value for a parameter of an engine. The controller may receive an operating value of the parameter. The controller may set, based on the desired value and the operating value, a position of an intake throttle valve of the engine to control air flow through a turbocharger of the engine.

Abstract: The disclosure describes an internal combustion engine and a method for operating an internal combustion engine, in which an electronic controller is programmed to determine whether the internal combustion engine is operating within a cylinder cutout enabling region and, when the engine operates in the cylinder cutout enabling region, to cutout one or more of the engine cylinders by causing the cutout cylinder's fuel injector to cease injecting fuel into cutout cylinder, and to also cause the still-active engine cylinders to operate with an additional amount of fuel such that a steady state engine torque output remains unchanged before and after the second cylinder is cutout.

Abstract: A controller may identify a plurality of sets of potential parameters associated with operation of an engine, wherein each set of potential parameters includes a potential setting of a turbine of a variable geometry turbocharger (VGT) of the engine and a potential setting of an intake throttle valve (ITV) of the engine. The controller may determine, based on the plurality of sets of potential parameters, a plurality of sets of predicted values, wherein each set of predicted values includes a predicted outlet pressure of a compressor of the VGT and a predicted temperature of an exhaust gas of the engine. The controller may determine respective scores of the plurality of sets of predicted values, and may select, based on the respective scores, a particular set of predicted values of the plurality of sets of predicted values. The controller may thereby control the turbine of the VGT and the ITV.

Abstract: An internal combustion engine system includes a control system with a monitoring mechanism producing data of engine operating state within a BMEP/speed envelope, and an electronic control unit structured to output a control command to vary at least one of a fuel delivery property or an air delivery property in the engine based on the data. Outputting the control command switches the engine between or among combustion modes that each satisfy different calibration criteria for optimizing aftertreatment function.
