下回る時に燃料供給を再開する燃料供給再開手段
とを備えた内燃機関の燃料供給制御装置において
、車速が第１の設定値を上回つた直後及び第２の
設定値を下回つた直後は車体の固有振動数の周期
に合わせて燃料の供給と供給停止とを断続させる
よう燃料供給停止手段及び燃料供給再開手段を制
御する燃料供給断続制御手段を設けたことを特徴
とする内燃機関の燃料供給制御装置。 fuel supply stop means for stopping the fuel supply to the engine when the vehicle speed detected by the vehicle speed detection means is high vehicle speed exceeding a first set value; and the vehicle speed after the fuel supply is stopped is smaller than the first set value. In the fuel supply control device for an internal combustion engine, the fuel supply control device includes a fuel supply restart means for restarting the fuel supply when the vehicle speed becomes lower than a second set value. The fuel supply intermittent control means is provided for controlling the fuel supply stop means and the fuel supply restart means so that the fuel supply and supply stop are intermittent in accordance with the cycle of the natural frequency of the vehicle body immediately after the vehicle body has fallen below the natural frequency. Fuel supply control device for internal combustion engines.
