  • Method for operating motor vehicle internal combustion engine
    Patent number: 9458799
    Abstract: A method for operating a motor vehicle internal combustion engine that has an exhaust tract with an exhaust gas purification unit acting catalytically and/or by filtration with which combustion air supplemented by exhaust gas diverging from the exhaust tract is fed to the combustion chambers of the internal combustion engine by exhaust gas branching off from the exhaust tract at a total exhaust gas recirculation rate. The total exhaust gas recirculation rate has a low-pressure proportion diverging downstream from the exhaust gas purification unit and a high-pressure proportion diverging upstream from an exhaust gas turbocharger turbine arranged in the exhaust tract. An essentially decreasing low pressure proportion is set with at least approximately the same operating points of the internal combustion engine with an increasing operating period of the exhaust gas purification unit.

    Patent number: 9447702
    Abstract: Embodiments of systems that are configured as a closed loop system with a pump, an evaporator, a power generator, and a condenser, the combination of which circulates a working fluid to generate electrical power. The embodiments are configured with a cooling system that can depress the local pressure at or near components that are the target of cooling, which in turn permits the cooling fluid to function at temperatures that can remove heat, even when the ambient temperature rises above desirable levels. In one embodiment, the system is configured with an ejector device that can use energy of the working fluid F in vapor phase to lower the pressure in a housing, or like environment, that encloses critical elements of the generator.

  • Wind generator hub assembly with hybrid sail blades
    Patent number: 9447690
    Abstract: A wind generator hub assembly with lightweight, high efficiency, hybrid airfoil/sail blades. The hub includes three to eight blade mounting surfaces each with a radially extending blade attached thereto. The blades are identical and wedge-shaped and evenly distributed radially around the hub. Gaps are created between each blade. Each blade has an airfoil profile with a curved outer skin layer. Each blade has a large curved leading edge and a flat trailing edge similar to an airfoil. The outer skin layer is secured along its leading edge and removeably attached along its trailing edge to a lightweight internal frame. Each blade includes a transversely aligned end cap with optional louvers. The blades are oriented so their outer skin layers face downwind and rotate towards their leading edges. When wind flows against the inside surface of the skin layers, the blades act as sails to produce thrust.
