    摘要: A system and method for monitoring at least one operating parameter indicative of an operating condition of an engine and controlling a turbocharger assist device to maintain desired operating conditions of the engine equipped with a turbocharger. In one embodiment, a controller is provided to control operation of a turbocharger assist device in an engine for generating electric power when an excess of energy exists in the exhaust of the engine to subtract work from a turbocharger drive shaft.

    摘要: Methods and systems are provided for operating a turbocharged engine. An engine system comprises a turbocharger, a bypass path, and a turbo-compound unit. The turbocharger may include a turbine mechanically coupled to a compressor. The turbo-compound unit may include a turbine mechanically coupled to a load, such as a generator. The turbo-compound unit may be coupled in a bypass path around the turbocharger turbine. In this manner, thermodynamic energy flowing through the bypass path may be harvested to increase the engine-operating efficiency. Further, gas flow through the bypass path may be adjusted to potentially improve the transient response of the turbocharger.

    摘要: A diffuser (30) for a centrifugal compressor (60) having a flow slot (34) formed between the leading edge portion (36) of a diffuser vane (32) and an adjoining diffuser wall (70) for the passage of working fluid (67) over the vane from the pressure side ((40) to the suction side (42) of the vane. The portion (38) of the working fluid passing over the vane is injected into the flow boundary region (43), thereby minimizing the growth of a flow separation zone (58) along the suction side.
