"Valve Service and Maintenance includes installing new seat inserts, cleaning or replacing valve guides, servicing the camshaft and camshaft bearings, and timing the valves."
气门维修包括镶配气门座,清洁或更换气门导管,保养凸轮轴和凸轮轴轴承,气门的正时调整。
3.
As the camshaft rotates, the lobe, or high spot of the cam, pushes against parts connected to the stem of the valve.
当凸轮轴旋转时，凸轮凸起的或者高点的位置，推动气门座。
4.
As the camshaft continues to rotate, the high spot moves way from the valve mechanism.
因为凸轮轴继续旋转，凸轮轴上的凸起部分离开气门装置。

The value-opening mechanism includes a valve lifter and a cam on a camshaft.
一套气门开启机构包括一个气门挺杆和一个在凸轮轴上的凸轮。
7.
The metal shaft, called the camshaft, typically has individual cams for each valve in the engine.
那金属轴叫凸轮轴，在发动机里的每个气门一般有各自的凸轮。
8.
Sometimes the camshaft is fitted directly into the cylinder head and operates on the valves without rockers.
有时，凸轮轴直接安装在气缸盖上并且不用摇臂控制阀门工作。
9.
"The cam lobes are so positioned on the camshaft as to cause the valves to open and close in the cylinders at the proper time with respect to the actions taking place,in the cylinders."
曲轴上凸轮凸角的位置使气门在恰当的时侯开关,以便与气缸的工作顺序相一致。
10.
If chain is not satisfactory, remove camshaft sprocket attaching bolt and remove timing chain with crankshaft and camshaft sprockets.
若正时链不令人满意，则拆下凸轮轴链轮固定螺栓，并拆下曲轴和凸轮轴链轮的正时链。
11.
Install the timing chain, crankshaft sprocket and camshaft sprocket with the timing marks aligne
安装正时链、曲轴链轮和凸轮轴链轮，使正时标记对齐。

"With this arrangement, the camshaft is directly below the valve lifter, and no push rods or rocker arms are necessary. "
"在这种装置中,凸轮轴直接装在气门挺杆下,并且不必有推杆或摇臂。"

Replacing the camshaft requires about eight hours; four additional hours are required for replacing camshaft bearings.
更换凸轮轴需要8小时左右;更换凸轮轴轴承需要额外增加4小时。
17.
"After the cam lobe moves out from under the valve lifter, the valve spring forces the valve up onto its seat again."
当凸轮凸角离开气门挺杆,气门弹簧使气门重新回到气门座上。
18.
Some high-performance engines have two separate camshafts, one for each set of inlet and exhaust valves.
一些高性能发动机有两个单独的凸轮轴，分别负责开关进气门和排气门。
