Glossary of Auto Terms

DriverSide's Car Dictionary has the most comprehensive definitions of automotive terms. This auto glossary can help you decipher what your mechanic is fixing and what the purpose or function of the particular auto part or accessory is for. We have taken the mystery out of automotive service jargon, so that you don't have to.

Fuel/Air Mixture

A mist-like vapor of gasoline and air. Like with pepper and exercise, the right amount is good, but too much of one can ruin things in a hurry. (Recall our definitions: Lean means too much air, Rich means too much fuel. This stuff has to be precise or fuel efficiency and performance suffer!)
