摘要:
The invention relates to a method that enables the inclination of the injection direction and the distribution of the penetration force of spray to be adjusted over a wide range, and an axially symmetrical spray shape to be obtained even when the injection hole is inclined, or the shape of the spray to be changed without inclining the injection hole. To provide a fuel passageway 203 as a swirling force adjustment means between the valve seat 201 and injection hole 101 of the fuel injector. This swirling force adjustment means adjusts the distribution of the swirling force of the fuel flowing into injection hole 101, and thus adjusts the spray shape obtained as a result.
摘要(中):
本发明涉及能够使喷射方向的倾斜和喷雾的穿透力的分布在宽范围内进行调节的方法,即使在喷射孔倾斜时也能获得轴对称的喷雾形状,或者 喷雾形状要改变而不会倾斜注射孔。 在燃料喷射器的阀座201和喷射孔101之间设置作为旋转力调节装置的燃料通路203。 这种旋转力调节装置调节流入喷射孔101的燃料的旋转力的分布,从而调节作为结果获得的喷雾形状。
