Abstract
An exhaust gas purification device of an engine comprising a particulate filter arranged in an exhaust passage. An electric motor able to impart a vehicle drive power separate from the engine and able to generate electric power from the engine is provided. After the particulate filter finishes being warmed up, when the temperature of the particulate filter is low, the output torque of the engine is increased and the amount of increase of the output torque is consumed by the power generating action of the electric motor.
