1·Modern car engines that use rolling or sliding tappets for transmitting the rapid up-down lifting motion of the spinning camshafts—to open and close the engine’s inlet and exhaust valves—seem immune.
使用滚柱挺杆或滑动挺杆来传动旋转凸轮轴做上下快速提升动作（开启和关闭发动机的进气阀和排气阀）的现代型汽车发动机似乎不会出现上述自动熄火的情况。
2·The chain drive consists of a duplex roller chain which drives both intake and exhaust camshafts.
链条驱动机构包括一条双排辊链，通过它来驱动进气和排气凸轮轴。
3·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。
4·Processing camshafts by the technique of high-speed-and-precision grinding can meet our satisfaction for high speed, efficiency and precision.
采用高速精密磨削方法和工艺加工凸轮轴可以满足高速、高效、高精度的加工要求。
5·The sedan camshafts re-melting and chilling process and production technique of shell mold camshaft castings to be re-melted and chilled were introduced.
介绍重熔淬火硬化处理凸轮轴工艺，以及供重熔淬火用的壳型凸轮轴的生产工艺。
