To operate as effectively as possible.

Meaning adapted from Wiktionary, available under CC BY-SA 4.0.


SIMPLE

“The team is firing on all cylinders today.”

“Your new marketing plan is firing on all cylinders.”

CONTEXTUAL

“After a slow start to the season, the players are finally firing on all cylinders and winning every game.”

“My brain is finally firing on all cylinders now that I have finished my second cup of coffee and started my morning tasks.”

COMPLEX

“With the new management team in place and the supply chain fully restored, the company is once again firing on all cylinders.”


The expression originates in the mechanics of the internal combustion engine, describing a state in which each cylinder contributes its spark and stroke to the machine’s output. When an engine fires on all cylinders, it achieves its maximum intended power; when it does not, the resulting imbalance is merely a mechanical failure. The phrase transitioned from technical description to a general metaphor for peak efficiency, though the date of this shift and the individuals responsible for its popularisation remain unrecorded.
