每缸两个喷嘴的典型示例 | |
(1) 活塞冷却喷嘴
必须检查活塞冷却喷嘴 (1) 机油流的位置。 将直径为 1.3 mm (0.05 in) 的钻杆插入节流孔内。 钻杆模拟正常工作压力下的机油流。 钻杆必须在位置 (A) 处穿过一个圆圈，圆圈直径为 5.0 mm (0.20 in)。 将钻杆放入第二个节流孔。 钻杆必须在位置 (B) 处穿过一个圆圈，圆圈直径为 13.0 mm (0.51 in)。 圆圈位于深度 (G) 处。 圆圈的位置是在距离气缸体顶部以下 50.0 mm (1.97 in) 处。
利用下列尺寸确定活塞冷却喷嘴组件的位置。
- 尺寸 (C) ... 25.9 mm (1.02 in)
- 尺寸 (D) ... 33.4 mm (1.32 in)
- 尺寸 (E) ... 26.9 mm (1.06 in)
- 尺寸 (F) ... 9.8 mm (0.39 in)
- 尺寸 (G) ... 50.0 mm (1.97 in)
- 尺寸 (D) ... 33.4 mm (1.32 in)
