Abstract

A turbocharger system includes: a high-pressure stage turbocharger including a high-pressure stage turbine disposed on an exhaust passage and driven by exhaust, and a high-pressure stage compressor disposed on an intake passage and driven by a rotational torque of the high-pressure stage turbine; and a low-pressure stage turbocharger including a low-pressure stage turbine disposed on the exhaust passage of a more downstream side than the high-pressure stage turbine and driven by exhaust, and a low-pressure stage compressor disposed on the intake passage of a more upstream side than the high-pressure stage compressor and driven by a rotational torque of the low-pressure stage turbine, wherein the high-pressure stage turbocharger includes an electric motor that assists a drive force of the high-pressure stage compressor.
