According to an embodiment of the present invention, an engine system having a turbo charger and a super charger comprises: a first suction line; a second suction line; a main suction line; an exhaust line; a turbo charger; and a super charger. The first suction line inducts external air. The second suction line is formed separately from the first suction line to induct external air. The main suction line allows the first suction line and the second suction line to be combined and is connected to a suction manifold of an engine. The exhaust line is connected to the exhaust manifold of the engine and discharges the exhaust gas of the engine to outside. The turbo charger compresses the sucked air in such a manner where a turbine is rotated by the exhaust gas passing through the exhaust line, and a compressor mounted on the first suction line is rotated by the turbine to transfer the compressed air to the main suction line. The super charger is installed on the second suction line and is selectively operated in accordance with an operation condition to compress the inducted air to be transferred to the main suction line. According to the present invention, in a state where the turbo charger and the super charger are applied, an exhaust gas recirculation (EGR) is stably provided to a suction side, and the sucked air is entirely compressed through the turbo charger. At this time, a turbo lag can be reduced through the super charger in rapid acceleration or initial acceleration. |
