PURPOSE: An exhaust gas recirculation apparatus is provided to maintain the temperature of engine oil by heat-exchanging exhaust gas with oil when an engine is initially started. CONSTITUTION: An exhaust gas recirculation apparatus(100) comprises a central pipe, a bypass pipe(130), a bypass valve, and a heat exchanging unit(150). Exhaust gas, exhausted from each cylinder of an engine, flows in the central pipe. The bypass pipe is connected to the bottom of the central pipe. The bypass valve is installed inside the bypass pipe. The heat exchanging unit is selectively branched from the bypass pipe by the bypass valve. |
