    Abstract: A vehicle propulsion system includes a controller configured to generate a control signal that dictates operation of a propulsion system of a vehicle having an engine and an electrically driven superturbocharger or a turbo-compounding turbine. Responsive to determining that the vehicle is one or more of entering into or traveling within an airflow restricting area, the controller is configured to change the operation of the propulsion system of the vehicle by reducing a power output by the engine. The controller is configured to reduce the power output by the engine to increase a power output of the electrically driven superturbocharger or the turbo-compounding turbine to propel the vehicle through the airflow restricting area.

    Abstract: Fuel injector wear compensation methodologies for use with internal combustion engines that alter the injection schedule over the life of the fuel injector(s) by using methods that conduct a primary injection of fuel in the engine (primary fuel event), per an injection schedule within an engine cycle; compare a measured engine parameter(s) to a reference value(s); and then alter the injection schedule applied to the engine, based on the comparing. Another method comprises: during injection events, inject a first fuel in a combustion chamber of the engine; measure an engine parameter(s) of the engine during operation; compare the engine parameter(s) to a reference value(s); add a post injection event of a second fuel during the injection events, based on the comparison. The methods can be applied with single or dual fuels.

    Abstract: A method for optimal fueling of an engine is disclosed. The method includes determining a quantity of exhaust residuals in each cylinder among a plurality of cylinders in the engine. Further, the method includes determining at least one of an intake and exhaust manifolds temperature, at least one of an intake and exhaust manifolds pressure, and a quantity of a first fuel being injected to each cylinder, and calculating a characteristic temperature of each cylinder based on the quantity of exhaust residuals, at least one of the intake and exhaust manifolds temperature and pressure, and the quantity of the first fuel. The method further includes determining a substitution rate of the first fuel for each cylinder based on the characteristic temperature, and controlling at least one of the quantity of the first fuel, and a quantity of a second fuel being injected to each cylinder based on the substitution rate.

    Abstract: Systems for rotating detonation combustion are provided herein. The system includes an inner wall and an outer wall each extended around a centerline axis, wherein a detonation chamber is defined between the inner wall and the outer wall, and an iterative structure positioned at one or both of the inner wall or the outer wall. The iterative structure includes a first threshold structure corresponding to a first pressure wave attenuation and a second threshold structure corresponding to a second pressure wave attenuation. The iterative structure provides for pressure wave strengthening along a first circumferential direction in the detonation chamber or pressure wave weakening along a second circumferential direction opposite of the first circumferential direction. The first circumferential direction corresponds to a desired direction of pressure wave propagation in the detonation chamber.

    Abstract: A vehicle control system examines characteristics of an upcoming segment of a trip of a hybrid vehicle. One or more locations in the upcoming segment of the trip are identified based on the characteristics as places where an engine of the vehicle is incapable of generating enough energy to power the vehicle through the locations. Operational settings of the vehicle are calculated based on the locations to operate the vehicle in a way that charges an energy storage device with energy that can be used to replace or supplement the energy provided by the engine to propel the hybrid vehicle over or through the locations. The one or more processors are configured to one or more of automatically control or generate a control signal for automated operation of the hybrid vehicle according to the one or more operational settings that are calculated.
