Abstract
A cooling system for an engine is provided. The cooling system includes an EGR device including an EGR passage for recirculating exhaust gas into an intake passage, an EGR valve for adjusting a flow rate of the recirculating exhaust gas, and an EGR cooler for cooling the recirculating exhaust gas, an EGR valve controller for controlling the EGR valve, coolant flow paths including a first flow path and a second flow path and where coolant circulates, a coolant pump for circulating coolant within the coolant flow paths, a flow rate control valve for adjusting a flow rate of the coolant through the second flow path, a temperature detector for detecting a coolant temperature within the first flow path, and a valve controller for adjusting a flow rate control valve opening based on the detected temperature.
