Abstract:
A hybrid system working machine is, during a normal working time, operated by a normal operation mode that the output of a power generator and the accumulated power of a capacitor are used while the engine is operated over a high−efficiency range at a low output. Switching of a selector switch to a high−speed running mode position and running operation enable long−distance and high−speed running of an increase in engine output by a high−output operation mode.
