His work transformed the cam from a simple mechanical timer into a precise control device that shapes how an engine makes power, and those early principles still define camshaft design to this day.

It's springtime! Time to start working on your project car, learn a new wrenching skill, discover what everything is under the hood (and how it works), or just spruce up your daily driver. All month, ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...
