The present disclosure relates to an engine control device for hybrid construction machinery, and more particularly, and an object of the present disclosure is to, in a hybrid excavator, in which a swing apparatus is electrically driven by being separated from a hydraulic power train system in the related art, satisfy a minimum rotational speed of an engine auxiliary motor which is necessary to satisfy a target charging amount required for an energy storage device, and improve fuel efficiency by removing unnecessary energy loss at low loads by controlling a rotational speed of an engine to be lower than a rotational speed of an engine determined based on a dial input and a mode input in the related art, in a case where a target power generation amount of the engine auxiliary motor is small in a low-load work situation.
