Abstract
A method for controlling an operation mode of an engine implementing cylinder deactivation (CDA) by a device for controlling an operation mode, may include determining whether a CDA operation is available by using an operation state signal of a vehicle, determining a fuel consumption prediction value or an exhaust temperature prediction value by the CDA operation when the CDA operation is available: and determining whether to enter a CDA mode by using at least one of the fuel consumption prediction value and the exhaust temperature prediction.
