An engine system may include an electric or mechanical supercharger and an LP-EGR, basically with a turbocharger, an EGR valve, a channel control valve, and a bypass valve, which control the flow rate of external air and exhaust gas, may be integrally operated, and a operation section may be divided into a turbo-lag and low torque section, a mid-load section, and mid/high-load section such that the open amount of EGR valve, channel control valve, and bypass valve may be optimally controlled, such that it may be possible to improve availability for a low-speed/high-load section with turbo-lag reduced, using supercharger and considerably increase the ratio of fuel efficiency improvement in the low-speed/high-load section, using LP-EGR operating with supercharger.
