主权项

1. An engine system including a turbocharger and a supercharger, comprising:
a first intake line for drawing external air; a second intake line for drawing external air formed separately from the first intake line; a main intake line to which the first intake line and the second intake line are joined, and the main intake line connected to an intake manifold of an engine; an exhaust line connected to an exhaust manifold of the engine, and the exhaust line discharging exhaust gasses of the engine to the outside; a turbocharger including a turbine rotated by exhaust gasses passing through the exhaust line and a compressor disposed at the first intake line, wherein the compressor is rotated by the turbine, compresses intake air, and transmits the intake air to the main intake line; and a supercharger disposed at the second intake line, wherein the supercharger compresses intake air, transmits the intake air to the main intake line, and is selectively operated according to a driving condition.
