る内燃機関の回転数制御装置。 The engine includes a passage that bypasses the intake throttle valve of the engine, a valve means that adjusts the opening degree of the bypass passage, and a means that detects the engine speed, so that the engine speed matches the target rotation speed when the engine is idling. In a rotation speed control device that feedback-controls the opening degree of the valve means, when the actual rotation speed exceeds the target idle rotation speed, it decreases at a constant rate, and conversely, when it falls, it decreases at a constant rate. a first means for outputting an increasing integral signal; a second means for outputting a signal proportional to the square of the deviation when the actual rotational speed is lower than the target rotational speed; third means for increasing the integral output of the first means by a value proportional to the square signal of the deviation; and A rotation speed control device for an internal combustion engine, comprising: a drive means for controlling the opening degree of the valve means based on the added output.
