Množina: sparks

1. A small but noticeable trace of some quality that might become stronger
2. A small fragment of a burning substance thrown out by burning material or by friction.

To emit or produce sparks.

Množina: spark advances

The timing of ignition relative to the position of the piston in an internal-combustion engine; SYN. lead.

Množina: spark arresters

1. A device to reduce sparking when electrical contacts are opened or closed.
2. A wire net to stop sparks from an open fireplace or smokestack.

Množina: spark catchers

Množina: spark chambers

An instrument that detects ionizing radiation from elementary particles; SYN. spark counter.
Electronic device for recording tracks of charged subatomic particles, decay products, and rays. In combination with a stack of photographic plates, a spark chamber enables the point where an interaction has taken place to be located, to within a cubic centimeter. At its simplest, it consists of two smooth threadlike electrodes that are positioned 1–2 cm/0.5–1 in apart, the space between being filled by an inert gas such as neon. Sparks jump through the gas along the ionized path created by the radiation. See particle detector.

Množina: spark coils

An induction coil used to create sparks.

Množina: spark gaps

1. A space between two high-potential terminals.
2. A unit consisting of electrodes and the space between them.

Množina: spark ignition engines

Množina: spark plugs

Fits into the cylinder head of an internal-combustion engine and ignites the gas by means of an electric spark; SYN. sparking plug, plug.
Plug that produces an electric spark in the cylinder of a gasoline engine to ignite the fuel mixture. It consists essentially of two electrodes insulated from one another. High-voltage (18,000 v) electricity is fed to a central electrode via the distributor. At the base of the electrode, inside the cylinder, the electricity jumps to another electrode earthed to the engine body, creating a spark. See also ignition coil. sparkplug

Singular of spark plugs is spark plug.

Množina: spark transmitters

An early radio transmitter using a discharge across a spark gap as the source of its power.
