    Abstract: Systems and methods are provided for reducing surge in a boosted engine system. One method comprises adjusting an opening of a compressor recirculation valve to allow a compressor recirculation flow based on a combination of a nominal compressor recirculation flow and a filtered nominal compressor recirculation flow. The nominal compressor recirculation flow may be calculated as a difference between a desired compressor flow rate based on a surge limit of compressor and an estimated throttle mass flow rate.

    Abstract: An engine system configured to adjust an output torque generated by the engine system in response to anticipated changes in a condition of a load. The engine system includes a load predictor, an air supply system, a fuel supply system, and an electronic control unit. The electronic control unit is configured to adjust the quantity of air and/or exhaust provided to an inlet manifold of an engine and to thereafter adjust the quantity of fuel delivered to the engine for a predetermined period of time. The delivery of the quantity of fuel is delayed from the adjustment to the quantity of air and/or exhaust to provide a torque boost responsive to the anticipated changes in the condition of the load. Fuel costs are reduced and the engine operates more smoothly in response to load changes.

    Abstract: A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes first and second bearings formed between an outer bearing race element disposed within the bearing bore an inner bearing race element disposed within the outer bearing race element and between the outer bearing race element and the shaft. The inner bearing race element rotates with the shaft and forms an extension segment having an open channel that, together with an annular surface on an inner side of a back of the compressor wheel, forms a U-shaped channel into which a ring seal is disposed. The ring seal sealably engages the inner bearing race element and also slidably and sealably engages the inner bore of the bearing retainer.

    Abstract: An evacuator is disclosed, and includes a body defining a central axis, a converging motive section, a diverging discharge section, at least one suction port, and at least one Venturi gap. The Venturi gap is located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. The evacuator also includes a fin positioned within the motive section of the body. The fin extends in the direction of the central axis.
