Abstract: PURPOSE: An exhaust-gas re-circulating system is provided to minimize head loss since there is little vertical movement of exhaust gas when the fluid passage of exhaust gas is switched by a valve set. CONSTITUTION: An exhaust-gas re-circulating system comprises an EGR(exhaust gas recirculation) line, an EGR cooler(150), a bypass line(160) and a 3-way valve set(170). Exhaust gas is re-circulated from an exhaust line to an intake line through the EGR line. The EGR cooler is installed on the middle of the EGR line. The bypass line bypasses the EGR cooler. The valve set is installed on the EGR line. The valve set selectively switches the flow of the exhaust gas to the EGR cooler or the bypass line.
