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