  "textContent": "An object of the present invention is to provide an EGR gas cooling system which can rapidly raise the temperature of cooling water after an engine is stated. The EGR gas cooling system of the present invention includes a main cooling water circuit (6)which circulates cooling water between an engine (3), a main radiator (7) that radiates heat of the cooling water of the engine (3) and a primary EGR cooler (1) that cools EGR gas by the cooling water and a low temperature cooling water circuit (9) which circulates the cooling water between the engine(3), a sub-radiator (10) provided integrally with or separately from the main radiator (7) to radiate heat in the cooling water and a secondary EGR cooler (2) that cools the EGR gas by the cooling water. A flow rate controller (12) which controls a flow rate of the cooling water is provided between the engine (3) and the sub-radiator (10) of the low temperature cooling water circuit (9).",
