An electrostatic atomization device that electrostatically atomizes condensed water and emits atomized water. The device includes a means which is intended to be actuated and which can be set in a number of different positions, and each of these positions corresponds to one of the operating states. The control device is further configured to maintain the pressurizing condition while the level of the sensed output pressure increases past the target pressure level, and to terminate the pressurizing condition in response to the sensed output pressure increasing to a level that exceeds the target pressure level by a predetermined differential value. A value for the rotation angle position is determined on the basis of the estimate, the at least one crankshaft rotation angle measured value and the transmission characteristic.
