噴射し、燃焼させる内燃機関において、燃料噴射
弁本体の針弁ストツパー上部に高周波振動子を埋
めこみ、その振動により燃料噴射期間中の針弁を
その摺動方向に高周波で振動させるように構成し
たことを特徴とする内燃機関の燃料噴射装置。 In internal combustion engines that directly inject fuel oil into the high-temperature, high-pressure air inside the cylinder and burn it, a high-frequency vibrator is embedded in the upper part of the needle valve stopper of the fuel injection valve body, and its vibration causes the needle valve to move during the fuel injection period. A fuel injection device for an internal combustion engine, characterized in that it is configured to vibrate at high frequency in a sliding direction.
