    • A liquid fuel injection device for internal combustion engines provides an elongate peripheral injector housing defining a cylindrical medial chamber with a fluid plenum having a fluid inlet at a first end and plural fluid exit ports at a second end that is carried within a combustion chamber of an engine cylinder. The plural exit ports are spacedly arrayed in both circumferential and axial directions and may be angularly oriented in the injector housing. The medial chamber of the injector housing rotatably carries an atomizer casement defining an internal chamber with plural circumferentially spaced inlet orifices at a first end which communicates with the fluid plenum of the first end of the injector housing and plural spray orifices at the second end. Each spray orifice of the atomizer casement carries a pressure swirl atomizer with output orifice arrayed to communicate with at least one of the exit ports defined in the second end of the injector housing at at least one rotary position of the atomizer casement relative to the injector housing. A first species of injection device provides electrically powered mechanism for rotating the atomizer casement relative to the injector housing and a second species provides pressurized fuel powered mechanism for such rotation. Both species allow adjustment of fuel injection timing and flow rate independently of each other.
    • 用于内燃机的液体燃料喷射装置提供了一个细长的外围喷射器壳体,其限定了具有在第一端处具有流体入口的流体增压室的圆柱形中间室,以及在第二端处的多个流体出口, 发动机气缸。 多个出口端口在圆周方向和轴向方向上间隔排列,并且可以在注射器壳体中成角度地定向。 喷射器壳体的内侧腔室可转动地携带雾化器罩,该雾化器罩在第一端处限定具有多个周向间隔开的入口孔的内部腔室,该第一端部与喷射器壳体的第一端部的流体通风室和第二端部的多个喷射喷嘴连通。 雾化器平板开口的每个喷孔都带有压力涡流雾化器,其输出孔排列成与喷雾器壳体的第二端中限定的至少一个出口连通,该至少一个出口与喷雾器壳体的至少一个旋转位置 。 第一种注射装置提供用于相对于注射器壳体旋转雾化器罩的电动机构,并且第二种类为这种旋转提供加压燃料动力机构。 两种物种都可以独立于彼此调整燃料喷射正时和流量。
