Abstract
The exhaust gas recirculation system comprises an exhaust recirculation pipe configured to recirculate an exhaust gas from an engine into an intake pipe of the engine, an exhaust gas heat exchanger connected to the exhaust recirculation pipe and configured to perform an heat exchange between the exhaust gas and an engine cooling water used for cooling the engine, a cooling water pipe configured to circulate the engine cooling water to the exhaust gas heat exchanger, and a heat insulating member forming a heat insulating layer on a heat transfer path from the exhaust gas heat exchanger to the outside.
