ABSTRACT:
An engine is provided with a dual cooling system having a head-side cooling water passage formed in a cylinder head, through which a cooling water can be circulated, and a block-side cooling water passage formed in a cylinder block, through which a cooling water can be circulated, in which a block-side circulation can be stopped without stopping a head-side circulation. An exhaust gas recirculation control device for such engine comprises a temperature sensor for detecting a temperature of the cooling water circulating the head-side passage (THW); and an exhaust gas recirculation (EGR) system for supplying an EGR gas to the engine. The EGR system performs the supply of the EGR gas when the cooling water temperature (THW) is higher than a predetermined temperature (THE), and stops the supply of the EGR gas when the cooling water temperature (THW) is lower than the predetermined temperature (THE). The predetermined temperature when the block-side circulation is stopped (THL) is set to be different from the predetermined temperature when the block-side circulation is performed (THH).
