| description | An engine cooling device including a water pump, a radiator, an exhaust heat recovery unit, and a coolant circulation circuit for circulating a coolant in these apparatuses includes a flow rate limiting means that limits the flow rate of the coolant that circulates in the exhaust heat recovery unit in the case where a temperature of a sensor element of an A/F sensor, that is disposed downstream of the exhaust heat recovery unit in an exhaust path, is below a preset activation temperature. An extent of opening of a second switching valve is made smaller in the case where the temperature of the sensor element is below the activation temperature than in the case where the temperature is equal to or higher than the activation temperature. |
