ENGINE CONTROL DEVICE OF WORK MACHINE, WORK MACHINE, AND ENGINE CONTROL METHOD OF WORK MACHINE
An engine control device of a work machine controls an internal-combustion engine of the work machine including a swing body, an implement attached to the swing body, a hydraulic actuator that operates the implement, a hydraulic pump that operates the hydraulic actuator, and the internal-combustion engine that drives the hydraulic pump and of which a rotation speed is changed according to a load. The engine control device of the work machine includes: a determination unit configured to determine whether a condition not requiring work with the implement is established; and an engine control unit configured to enable control at relief time of determining a target rotation speed targeted by the internal-combustion engine based on horsepower sucked by the hydraulic pump of when a hydraulic oil ejected by the hydraulic pump is relieved when the condition is established, and disables the control at relief time when the condition is not established.
