Last month's "How It Works" story gave you the basics of the four-stroke cycle, describing the motion of the intake and exhaust valves in relation to the piston moving up and down in the cylinder.

There's more to the world of camshafts than just up-and-down motion. While they still push valves like they did a hundred years ago, the technology of camshaft and valvetrain design has made huge ...

Cam–follower systems are integral to a myriad of engineering applications, from automotive valve trains to precision industrial machinery. The current research landscape encompasses comprehensive ...

What does a mechanical engineer need to know about control theory? More than he did ten years ago. The same is true for electrical engineers and their understanding of mechanical dynamics. More and ...
