転数域回避対策装置。 A lower limit detection means for detecting the lower limit of the rotation speed of the main engine in the torsional vibration dangerous rotation speed range, and a scavenging pressure limiter canceling solenoid valve that is energized when the lower limit detection means detects the lower limit of the rotation speed dangerous for torsional vibration. When the lower limit of the dangerous rotation speed range for torsional vibration is detected, a first timer circuit including rotation detection is activated to avoid the rise and fall of the amount of governor fuel slack caused by turning on and off the scavenging pressure limiter cancel solenoid valve. and upper limit detection means for detecting the upper limit of the dangerous rotation speed range for torsional vibration, and when the upper limit detection means detects the upper limit of the dangerous rotation speed for torsional vibration, turning on and off a solenoid valve for scavenging pressure limiter cancelling. A device for avoiding dangerous rotational speed ranges, comprising a second timer circuit for avoiding rises and falls of governor fuel rack amount that occur.
