  • Patent number: 9593597
    Abstract: A novel Rankine cycle system configured to convert waste heat into mechanical and/or electrical energy is provided. The system provided by the present invention comprises a novel configuration of the components of a conventional Rankine cycle system; conduits, ducts, heaters, expanders, heat exchangers, condensers and pumps to provide more efficient energy recovery from a waste heat source. In one aspect, the Rankine cycle system is configured such that three distinct condensed working fluid streams are employed at various stages in the waste heat recovery cycle. A first condensed working fluid stream is vaporized by an expanded first vaporized working fluid stream, a second condensed working fluid stream absorbs heat from an expanded second vaporized working fluid stream, and a third condensed working fluid stream removes heat directly from a waste heat-containing stream. The Rankine cycle system is adapted for the use of supercritical carbon dioxide as the working fluid.

    Abstract: An air gap-insulated exhaust manifold (10) for a supercharged internal combustion engine (1), preferably of a motor vehicle has an engine flange (11) fastening the exhaust manifold to an engine block (2) and a turbine flange (12) fastening the exhaust manifold to a turbine (8) of an exhaust gas turbocharger (7). Two inner pipes (13, 14) lead from an inlet opening, for exhaust gas, adjacent to the engine flange to an outlet opening (18), for exhaust gas, adjacent to the turbine flange. An outer pipe (15) envelopes the two inner pipes, forming an air gap insulation (21), and extends from the engine flange to the turbine flange. A separation partition (16) separates, in the interior space (22) of the outer pipe, two interior spaces (23, 24), in which one each of the two inner pipes is arranged. Reduced wear is achieved with the partition arranged loosely at the turbine flange.

  • Patent number: 9587597
    Abstract: In the present invention, an internal combustion engine is provided with an in-cylinder fuel injection valve and a secondary air supply device and is formed so as to make possible first catalyst warming control and second catalyst warming control that promote the raising of the temperature of an exhaust gas purification catalyst. The first catalyst warming control comprises control to inject fuel from the in-cylinder fuel injection valve during the compression stroke to form a stratified state, and control to greatly delay ignition timing. The second catalyst warming control comprises control to supply secondary air to an engine exhaust gas passage. The internal combustion engine executes the first catalyst warming control after startup and, after the first catalyst warming control is executed, carries out control (third catalyst warming control) to execute the first catalyst warming control and the second catalyst warming control simultaneously.

  • Patent number: 9587550
    Abstract: A component of an exhaust system for a combustion engine, particularly of a motor vehicle, has a hollow jacket at least partially surrounding the component. An intermediate space is surrounded by the walls of the hollow jacket and is closable in a pressure-tight manner. The intermediate space is fluidically connected to a vacuum generating device via a vacuum connection line and via a vacuum connection point of the component. With the vacuum generating device, a vacuum can be generated in the intermediate space. Through arrangement of a filler material, such as a support structure and/or of a fiber material and/or of a foam, in the intermediate space the stability of the hollow jacket can be improved.

  • Patent number: 9581145
    Abstract: A variable area fan nozzle comprising an array of hinged rigid petals and a petal actuation system in which the principle of actuation is realized by changes in shape (i.e., deformation) of the actuators rather than by movement of cooperating mechanical parts. Because these actuators have no rotating or sliding mechanical components, wear and associated maintenance are reduced. Each deformable actuator has a portion made of shape memory alloy that has been trained to change shape in a specific manner when heated to a temperature above a transition temperature. In addition, each shape memory alloy actuator is shaped to act as a fairing to reduce aerodynamic drag.
