(1) 左侧凸轮轴总成

(2) 右侧凸轮轴总成

(A) 新凸轮轴总成上止推垫圈槽的厚度 ... 8.75 ± 0.05 毫米 (0.344 ± 0.002 英寸)

(B) 定位销伸出凸轮轴总成的长度 ... 12.0 ± 0.5 毫米 (0.47 ± 0.02 英寸)

(C) 新止推垫圈的厚度 ... 8.50 ± 0.05 毫米 (0.335 ± 0.002 英寸)

(D) 轴颈表面尺寸

轴承轴颈直径 ... 91.88 ± 0.02 毫米 (3.617 ± 0.001 英寸)
安装后凸轮轴轴承上的孔径 ... 92.00 ± 0.06 毫米 (3.622 ± 0.002 英寸)

注: 新凸轮轴总成的轴向间隙为 0.15 到 0.35 毫米 (0.006 到 0.014 英寸)。

(E) 具体的凸轮轴凸轮升程

进气凸轮升程 ... 12.7500 毫米 (0.50197 英寸)
喷油凸轮升程 ... 13.7313 毫米 (0.54060 英寸)
排气凸轮升程 ... 13.2500 毫米 (0.52165 英寸)

请采用以下步骤来确定实际的凸轮升程:

  1. 测量凸轮轴凸轮高度 (F) 。

  1. 测量基圆 (G) 。

  1. 用凸轮轴凸轮高度 (F) 减去基圆 (G) 。 二者之差即为实际凸轮升程。
