Meaning and Usage

The term "lobe of cam" typically refers to a part of a camshaft, which is an essential component in internal combustion engines. It describes the protruding section of the cam around which the follower rotates as the camshaft turns. The lobe's shape allows it to convert rotational motion into linear motion, playing a crucial role in the timing of valve openings and closings in an engine.

This term is mostly used in technical and mechanical contexts, specifically among automotive engineers and mechanics. Its usage is more prevalent in written contexts, such as manuals, technical documents, and engineering textbooks.
