暖気(だんき) has two distinct uses: warm air (meteorology) and warming up an engine (automotive).

SENSE 1 — WARM AIR:
Used in weather reports and meteorology. Often paired with 寒気(かんき) (cold air).

SENSE 2 — ENGINE WARM-UP:
Running an engine at idle to bring it to operating temperature. Also written 暖機(だんき) (with the kanji for "machine").

  • 暖気(だんき)運転(うんてん): idling to warm up
  • 暖気(だんき)が終(お)わる: the warm-up is finished

Usage

Modern cars generally do not require long warm-up periods, so this sense is becoming less common in everyday conversation.
