ENGINE CONTROL DEVICE FOR HYBRID WORK MACHINE, HYBRID WORK MACHINE, AND METHOD FOR CONTROLLING ENGINE OF HYBRID WORK MACHINE

摘要

This engine control device for a hybrid work machine is a control device that controls an internal combustion engine installed in a hybrid work machine including a work machine that operates by a working oil supplied from a hydraulic pump, the internal combustion engine driving a power generator motor and said hydraulic pump with generated power, wherein, when the power generator motor generates electric power while the internal combustion engine is in operation, torque necessary for making the power generator motor generate electric power is increased with the lapse of time, and absorption torque absorbed by the hydraulic pump is reduced.
