Abstract:
1. A two-stage turbocharged engine system, comprising: an internal combustion engine; a high-pressure turbocharger having a high-pressure turbine for rotating a high-pressure compressor through a connecting shaft; a low-pressure turbocharger having a low-pressure turbine for rotating a low-pressure compressor by means of a second connecting shaft; a low-pressure intake line for fluidly connecting the outlet of the low-pressure compressor to the inlet of the high-pressure compressor; a high-pressure intake line for fluidly connecting the outlet of the high-pressure compressor to an air cooler; and a bypass device for selectively fluidly connecting a first branching point located in the low-pressure intake line to a second branching point located in the high-pressure intake line to thereby bypass the high-pressure compressor, and wherein the bypass device is located closer to the low-pressure compressor than to the high-pressure compressor.
