PROBLEM TO BE SOLVED: To provide a marine engine rotation speed control method which enables a marine engine to perform complete combustion by curbing an excessive fuel supply.SOLUTION: In a marine engine rotation speed control method, an engine is operated in a manner that: determines presence or absence of disturbance and a characteristic thereof on the basis of magnitude of pitch of a vessel body; adjusts a rotation speed to a target rotation speed with a normal control characteristic when determining the absence of the disturbance; and manipulates a proportional gain, in a case of PID control for example, so as to keep the engine in an allowable rotation speed fluctuation range and allowable torque fluctuation range when determining the presence of cyclic disturbance.SELECTED DRAWING: Figure 1

    【課題】燃料の過剰供給を抑制し完全燃焼を行わせることができる舶用エンジンの回転数制御方法を提供する。【解決手段】船体のピッチングの大きさに基づき航行時の外乱の有無およびその性状について判断し、外乱がないと判断した場合には通常の制御特性によって回転数が目標回転数になるように制御し、外乱が周期性であると判断した場合には、例えばPID制御の場合は比例ゲインを操作し許容される回転数変動及びトルク変動の範囲でエンジンを運転する。【選択図】 図1
