Abstract
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.
