Claims (1)
係して調整する燃料圧力調整器の操作圧力室への操作圧
力通路に、温度に応じてこの通路を選択的に吸気管ある
いは大気へ接続する温度窓・動圧力切換弁を設け、所定
値以下の燃料温度では吸気管負圧を、また所定値以上の
燃料温度では大気圧を、燃料圧力調整器の操作圧力室へ
供給することを特徴とする、燃料噴射式エンジンの燃料
圧力制御装置。Depending on the temperature, this passage is selectively connected to the intake pipe or to the atmosphere to the operating pressure passage to the operating pressure chamber of the fuel pressure regulator that regulates the pressure of the fuel supplied to the injector in relation to the intake pipe negative pressure. The fuel pressure regulator is equipped with a temperature window/dynamic pressure switching valve that supplies negative pressure to the intake pipe when the fuel temperature is below a predetermined value, and atmospheric pressure when the fuel temperature is above a predetermined value to the operating pressure chamber of the fuel pressure regulator. A fuel pressure control device for a fuel injection engine.
