  • Patent number: 10975790
    Abstract: Systems and methods are provided for using an electric machine as a generator to control boost during an engine cold start. In one example, a method may include receiving a request to increase an engine load during the engine cold start, determining an available capacity of a battery, operating the electric machine as a generator to increase the engine load with an electrical load, and responsive to the available capacity of the battery being less than a charge threshold, charging the battery with the electrical load while generating an increased boost pressure with an electric boosting device by powering the electric boosting device via the battery, and coordinating an amount of the increased boost pressure to compensate the electrical load. By increasing the engine load during the engine cold start, an exhaust gas temperature may be increased to achieve catalyst light-off.

  • Patent number: 10954797
    Abstract: The present application provides a turbine rotor blade including an airfoil shape. The airfoil shape may have a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance (e.g., inches) by multiplying the Cartesian coordinate values of X, Y and Z by a height of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values may be joined smoothly with one another to form a complete airfoil shape.
