    Abstract: A variable geometry turbocharger includes a vane pack having rotatable vanes constrained by a pair of vane rings held together by a plurality of pins. A first end of each pin can be configured with a head. Each pin is received in a pair of aligned apertures in the vane rings such that the head of each pin engages one of the vane rings. A second end of each pin is deformed (e.g., by orbital riveting) such that it engages the other vane ring. Thus, a clamp load is applied to the vane rings, which can control the parallelism and distance between the vane rings so that the vanes can rotate with a minimum clearance without jamming. Also, the pins can maintain vane axle apertures in the vane rings in the correct angular position relative to each other. Such a vane pack configuration can reduce process time and cost.

    Abstract: An exhaust system with post-operation cooling for a vehicle is provided. The vehicle generally has a heat generating device that generates exhaust gas. The exhaust system includes an exhaust gas conduit through which at least a portion of the exhaust gas is flowable and dischargeable, and at least one exhaust gas component in fluid communication with the exhaust gas conduit. The exhaust system also includes an air intake conduit through which outside air is flowable, and an air pump in fluid communication with the air intake conduit. The air intake conduit is in fluid communication with the exhaust gas conduit upstream of the at least one exhaust gas component. The air pump is configured to draw the outside air into the air intake conduit such that the outside air is supplied to the exhaust gas conduit to cool the at least one exhaust gas component.

  • Patent number: 9010116
    Abstract: A vacuum source arbitration system is disclosed. In one example, vacuum is supplied to a vacuum reservoir via an ejector during a first condition, and vacuum is supplied to the vacuum reservoir via an engine intake manifold during a second condition. The approach may provide a desired level of vacuum in a reservoir while reducing engine fuel consumption.

  • Patent number: 8997462
    Abstract: An engine system comprising: an exhaust gas system for removing exhaust gas from the engine; a turbocharger comprising a compressor for inducing air towards the engine and a turbine provided along the exhaust gas system and driven by removed exhaust gas for powering the compressor; a hydrogen delivery apparatus adapted to deliver hydrogen to the exhaust gas system such that the hydrogen can combust and expand, thereby increasing the speed of the turbine. The increased speed of the turbine operation decreases turbo lag and increases engine responsiveness.

  • Patent number: 8997488
    Abstract: The present invention relates to a turbocharged reciprocating piston engine, and to a method for operating said engine. The combustion chamber includes at least one inlet valve (10), one outlet valve (13) and at least one additional charging valve (11), for the additional feed of compressed air to bridge the turbo lag, that are each operatively connected to the crankshaft via a camshaft and the operative connection of the charging valves to the crankshaft can be deactivated, with the result that the at least one charging valve (11) remains closed. An approximately stoichiometric combustion mixture is achieved by a turbocharger (4) and a throttle valve (8). By displacement of the opening instant of the charging valves (11), air can be pumped from the cylindrical combustion chambers into the compressed air tank (14). An additional compressor (24) can likewise deliver air into the compressed air tank (14).
