rev

One crankshaft turn

Rev is short for revolution, specifically of an engine—the number of times the crankshaft rotates per minute.

A tachometer measures revs.

To rev an engine is to increase its speed, especially while stationary: He revved the motorcycle at the stoplight.

Figuratively, to rev up is to energize or prepare for action: The team was revving up for the finals.

Rev also appears as an abbreviation for Reverend.
