1. The piston travels down on the intake stroke, up on the compression stroke, down on the power stroke and up on the exhaust stroke. 进气行程，活塞下行；压缩行程，活塞上行；做功行程，活塞下行；排气行程，活塞上行。
2. The priority encoder tests the CAM cell array to determine if the CAM cell array has errors by comparing search data with data stored in the CAM cell array. 优先编码器通过比较搜索数据与存储在CAM存储单元阵列中的数据来测试CAM存储单元阵列、以确定CAM存储单元阵列是否有错误。
3. Based on the measured data of a cam, the computer can analyze and find out the movement regularity of the cam follower lever, thus obtaining the theoretic profile of the cam. 提出了根据凸轮的测量数据，通过计算机分析处理，找出推杆从动件的运动规律，获得凸轮的理论轮廓曲线的方法。
4. YX-XK173 type CNC cam milling machine is primarily used for processing all kind of involute S type cam and arc cam of the automotive brake. XK173型数控凸轮铣床，主要用于加工汽车制动器中各种渐开线“S”型凸轮和圆弧凸轮。
