n. A device that produces alternating current for distribution to the spark plugs, used in the ignition systems of some internal-combustion engines.

n. a dynamo that provides power to the spark plugs of a small internal combustion engine

n. A small electric generator with an armature rotating in a magnetic field, having a secondary winding that generates a high voltage, such as one used to generate a voltage sufficient to cause a spark to jump between the poles of a spark plug in an internal-combustion engine.

n. A magneto-electric machine: as, a magneto-motor.

n. A combining form of magnet or magnetic, often implying especially magneto-electric.

n. Specifically, the electric generator used as the source of the current in internal-combustion motors (the engines of motor-cars in particular) to cause the spark which ignites the combustible mixture.

n. a small dynamo with a secondary winding that produces a high voltage enabling a spark to jump between the poles of a spark plug in a gasoline engine
