Air Cooled

Removing heat from the engine by circulating air across the cylinder block and heads.

Air Cooling

Simple method of engine cooling that relies on forced airflow over extended metal fins on the cylinder head and the block to maintain proper operating temperature.

Air Core

A method of constructing coils or transformers in which thee wire is wound on a hollow, air-filled form instead of one using magnetic material in the core.

Air Core Coil

A method of constructing coils or transformers in which the wire is wound on a hollow form instead of one using magnetic material such as soft iron.

Air Cushion Restraint System

A term used for air bag system.

Air Dam

Tubes, channels, or other tubular structures used to carry air to a specific location.

Air Filter

A filter that removes dust, dirt, and particles from the air passing through it.

Air Foil

The inverted wing of a race car designed to increase downward aerodynamic force and, with it, vehicle traction.

Air Gap

A small space between parts that are mated magnetically or electrically.

Air Hoist
