<p><P>PROBLEM TO BE SOLVED: To set engine speed with high accuracy using an input part and a display, drive an engine according to the set engine speed suitable for a work environment by just operating an on/off switch of the input part, and to prevent waste of fuel, overload of an excavator, overheat, and insufficient power during work. <P>SOLUTION: In this engine speed control system of the excavator, an operator can set engine speed. The system includes: the input part for outputting a setting process to a setting signal and outputting an on/off signal that determines the driving possibility of the engine at a set engine speed; a control part for receiving the setting signal, storing the set engine speed, receiving the setting signal and an on/off signal, outputting an output signal corresponding thereto, and controlling drive of the engine at the engine speed set by the on/off signal; and the display in which the output signal is inputted and that visually outputs the driving possibility of the engine speed that is set or in the setting process. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
