Hybrid work machine, and auto-stop control method for engine of hybrid work machine
A hybrid hydraulic shovel (1) is provided with: an engine (4); a generator motor (5); a capacitor (12); a cooling device (80) for cooling the capacitor (12); and a controller (41). The cooling device (80) is provided with: a circulation mechanism (81) for causing a coolant to circulate; and a cooler (85) which uses output of the engine (4) to cool the coolant. In cases when it is determined that the capacitor (12) is in an overheated state, the controller (41) prohibits an auto-stop operation of the engine (4).
