    • PURPOSE: To improve the rate of air utilization to the sprayed fuel, by a method wherein a plurality of nozzle holes are opened to end-walls along a plurality of concentric peripheries around the center line of sprayed fuel, and the angle of spray from each periphery to the center line is made different in accordance with the distance from the center line.
      CONSTITUTION: The fuel is injected, cylindrically, from a fuel injection hole 2, colliding against the recess 11 of an end-wall 4, spreading in a disk-shaped filmy form. On the other hand, the air or the vapor coming from a passge 6, is injected to the outside in high velocity from nozzle holes 12, at the same time, the above- mentioned film in the shape of a disk is injected from injection holes 12 to a combustion chamber 9, too. When the quantity of fuel is increased, the disk shaped film is spread out to an end-wall 4a, too, and is injected from a nozzle 8 together with the air and so forth. With the condition being as such, the sprayed fuel from nozzle holes 12 and 8, of which angle of spray are different to each other, are caused to collide against each other, mixed and stirred up, thus the rate of air utilization by the sprayed fuel can be increasd, regardless of the combustion load.

    • 目的:为了提高喷涂燃料的空气利用率,通过以喷射燃料的中心线为中心的沿着多个同心圆周向端壁敞开多个喷嘴孔的方法,以及喷射燃料的喷射角度 根据距离中心线的距离使得与中心线的周边不同。 构成:燃料从燃料喷射孔2以圆柱形方式喷射,与端壁4的凹部11碰撞,以圆盘形的薄膜形式展开。 另一方面,来自密封件6的空气或蒸气从喷嘴孔12以高速喷射到外部,同时,上述的盘状的膜从注射孔 12也到达燃烧室9。 当燃料量增加时,盘状膜也被扩展到端壁4a,并且与空气等一起从喷嘴8喷射。 在这样的条件下,使喷雾孔12,8喷射的喷射燃料彼此不同的喷射燃料彼此碰撞,混合搅拌,由此喷射的空气利用率 燃料可以增加,而不管燃烧负荷如何。
