ENGINE CONTROL DEVICE MOUNTED ON CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an engine control device mounted on a construction machine for changing an output when a work is started as necessary and reducing fuel consumption without generating an engine failure for a rapid increase in load of a hydraulic pump. SOLUTION: In a control of an engine mounted on a construction machine, the control is characterized by detecting a load change in a hydraulic pump when a working machine is changed from a non-operating state to an operating state and increasing output torque of idling of the engine when the load change is judged to be rapid.
