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。

If the valves do not open and close at the right time or at all, air cannot get in and exhaust cannot get out, so the engine cannot run.

如阀门打开或关闭的时间不对或根本打不开或关不住，空气无法进入，废气无法排出，因此发动机不运转。

Close the clamp for the APU exhaust extension.
