Abstract: This disclosure is directed towards an engine component sleeve with an integrated heat transfer arrangement. The sleeve includes a wall defining a passageway, and at least heat transfer arrangement. Each heat transfer arrangement includes at least one cavity enclosed within the wall and a working fluid located within the cavity.

Abstract: A turbocharger system comprises: a turbocharger having a rotatable shaft arranged to be driven by exhaust gases from an associated engine and coupled to a turbocharger electrical machine; and a controller configured to switch the turbocharger electrical machine between a first mode in which electrical energy is drawn from the turbocharger electrical machine acting as a generator and a second mode in which energy is provided to the turbocharger electrical machine to act as a motor. The controller may be configured to switch between the first mode and the second mode based upon the power factor for the electrical energy generated by or supplied to at least one of: the turbocharger electrical machine; and an engine electrical machine coupled to the associated engine.

Abstract: A method is provided for a computer based design system. The method may include selecting a first plurality of sets of design parameters of a design model representing a design application and individually simulating the design model for each set of the first plurality of sets of the design parameters to create a respective plurality of sets of output parameters corresponding to the design parameters. The method may also include choosing at least one set of the design parameters with a corresponding set of output parameters that satisfy predetermined criteria and selecting a second plurality of sets of the design parameters based on the at least one set of the design parameters.
