Abstract:
An EGR cooling apparatus includes a first EGR cooling-water passage (passage parts) to cause cooling water flowing out of an engine to an engine cooling water passage to return to the engine cooling water passage via an EGR cooler; a second EGR cooling-water passage (passage parts) to cause cooling water flowing out of a radiator to the engine cooling water passage to return to the second EGR cooling-water passage via the EGR cooler; a three-way valve for switching a flow of cooling water for the EGR cooler between a first EGR cooling-water passage and a second EGR cooling-water passage; and an electronic control unit (ECU) to control the three-way valve to switch a flow of cooling water to the EGR cooler between the first EGR cooling-water passage during warm-up of the engine and a second EGR cooling-water passage after warm-up.

Claim (Index 1):
An EGR cooling apparatus provided with an EGR cooler and configured to cause a cooling water that circulates through an engine cooling device for cooling an engine to flow to the EGR cooler to cool EGR gas flowing through the EGR cooler,\n wherein the engine cooling device includes a radiator, an engine-side water pump, and an engine cooling water passage, the engine cooling device is configured to operate the engine-side water pump to cause the cooling water to circulate through the engine cooling water passage via the engine, the radiator, and the engine-side water pump, the engine, the radiator, and the EGR cooler each include a water inlet for inflow of the cooling water and a water outlet for outflow of the cooling water, and the EGR cooling apparatus includes:\n a first EGR cooling-water passage configured to allow the cooling water flowing out from the water outlet of the engine to the engine cooling water passage to return to the engine cooling water passage via the EGR cooler; \n a second EGR cooling-water passage configured to allow the cooling water flowing out from the water outlet of the radiator to the engine cooling water passage to return to the engine cooling water passage via the EGR cooler; \n a flow switching unit configured to switch a flow of the cooling water for the EGR cooler between the first EGR cooling-water passage and the second EGR cooling-water passage; and \n a control unit configured to control the flow switching unit to switch the flow of the cooling water for the EGR cooler to the first EGR cooling-water passage when the engine is in a state during warm-up and switch the flow of the cooling water to the second EGR cooling-water passage when the engine is in a state after warm-up.
