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: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, during a cold start, a method may include adjusting a position of a first valve disposed in an exhaust gas recirculation (EGR) passage based on an engine operating condition, the EGR passage coupled between the first exhaust manifold coupled to a first set of exhaust valves and the intake passage, upstream of a compressor. As one example, the engine operating condition may include an engine temperature or a temperature of a catalyst disposed in the exhaust passage.

Abstract: A system and method is provided for controlling an electric machine rotatably coupled to a rotatable shaft of an electronically-controlled one of a turbocharger and an exhaust-driven turbo supercharger fluidly coupled to an exhaust duct of an internal combustion engine. An operating temperature of a component of the engine is determined or estimated an operating temperature of a component of the engine or coupled to the engine, which is compared to a threshold temperature. The electric machine is controlled to operate as a motor in response to the determined or estimated temperature of the component being below a threshold temperature.

Abstract: An internal combustion engine comprises a supercharger 34 having a compressor 34a and a turbine 34b and an EGR apparatus 50 having an exhaust recirculating pipe 51, an upstream EGR valve 52 and a downstream EGR valve 53. An electronic control unit 60 fully opens the upstream EGR valve 52 and controls an EGR amount by the downstream EGR valve 53 when a peak value of an exhaust pressure increases excessively. Thereby, since exhaust volume increases, the peak value of the exhaust pressure falls. Therefore, damage of parts of an exhaust system can be avoided. The electronic control unit 60 fully opens the downstream EGR valve 53 and controls the EGR amount by the upstream EGR valve 52 when the peak value of the exhaust pressure decreases excessively. Thereby, since the exhaust volume decreases, the peak value of the exhaust pressure rises. Therefore, supercharging can be continued while an EGR gas is being introduced.
