喷油器控制连杆

(1) 喷油器

(2) 左控制轴

(3) 曲拐

(4) 控制杆

(5) 齿条

(6) 操纵杆

(7) 调速器轴

(8) 右控制轴

(9) 横轴

喷油器 (1) 位于每个缸盖中。 齿条 (5) 的位置用于控制喷入到气缸中的燃油量。 将齿条从喷油器上拉出则会增加燃油量。 将齿条推入喷油器中则会减少燃油量。

齿条位置由曲拐 (3) 进行更改。 控制杆 (4) 会使曲拐发生移动。 控制杆有一个位于顶部的调整螺钉。 调整螺钉用于同步喷油器。 控制杆由弹簧进行加载。 如果一个喷油器的齿条发生卡滞,则调速器将依然可以控制其他齿条,因此发动机可以停机。

发动机右侧上的每个控制杆都由操纵杆 (6) 连接到右控制轴 (8) 上。 当可以从发动机前部看到调速器轴 (7) 并且调速器轴以顺时针方向旋转时,则调速器连杆的作用力将会使右控制轴沿逆时针方向移动。 这个逆时针方向就是 "FUEL ON"(供油)位置。

右控制轴 (8) 和左控制轴 (2) 通过横轴 (9) 彼此相连。 发动机左侧上的喷油器和左控制轴之间的连杆与右侧上的连杆相似。

如果连杆从调速器上断开,则控制连杆的重量将会使喷油器齿条移至 "SHUTOFF"(断油)位置,因此发动机将会停机。
