The results of the test show that by using ceramic composite tappet,the wear of the tappet can remarkably be reduced and the wear of matching cam can also be recuced by two thirds.
试验结果表明，采用陶瓷复合挺柱后，不仅挺柱本身的磨损量大为下降，与其配对的凸轮的磨损也下降了三分之二。

On stripping down a damaged motor, the tappets are invariably found to be heavily pitted and bits of metal broken off the camshaft lobes.
拆解报废的发动机就会发现推杆无一例外地存在严重的麻坑及从凸轮轴凸轮脱落的金属磨屑。
Unfortunately, though flat tappets from China are cheap, their metallurgy is suspect-and the same goes for the quality of their machining, heat treatment and surface-hardening.
不幸的是尽管中国制造的平头挺杆物美价廉，但是其冶金技术遭到质疑，加工、热处理、表面硬化质量也遭质疑。
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。
