Camshaft - a cylindrical rod with concentric, yet oblong, lobes arranged along the shaft. Designed to activate valve stems or similar mechanical linkage of an archetypical internal combustion engine in a specific order, this is accomplished by the lobe protrusion outside the diameter of the main shaft directly contacting the valve stem, or other mechanical interface which is connected to the valve stem. Compressing the valve spring as the shaft rotates, the height of the lobe protrusions will be directly proportional to the distance a valve opens. The curvature of the lobe and the speed of the camshaft will determine how long the valve is "open". Being a static part with no moving parts internal to the camshaft, it can easily be strengthened and is a common part to replace when a different behavior of the valves is desired for performance or efficiency purposes.

Damn, you're good at remembering your definitions. I wish I could do half as well.
Your word means small, of little significance. Often this word is used pejoratively.
