The act of igniting, kindling, or setting on fire.

Ignition in an internal-combustion engine while the inlet valve is open or before compression is completed.

The act of kindling or the state of being kindled; ignition. Locke.

ameless; as, an aphlogistic lamp, in which a coil of wire is kept in a state of continued ignition by alcohol, without flame.

arge which bursts a shell, etc. (b (Mining) A small quantity of fine powder to secure the ignition of a charge of coarse powder in blasting. -- Charge and discharge (Equity Practice), the old mode or form of taking an account before a master in chancery. -- Charge sheet, the paper on which are entered at a police sta…

two volumes of hydrogen with one volume of oxygen, which explodes with a loud report upon ignition. -- Detonating powder, any powder or solid substance, as fulminate of mercury, which when struck, explodes with violence and a loud report. -- Detonating primer, a primer exploded by a fuse; -- used to explode gun cotto…

turning two streams of gas, one oxygen and the other hydrogen, or coal gas, in a state of ignition, upon a ball of lime; or a stream of oxygen gas through a flame of alcohol upon a ball or disk of lime; -- called also oxycalcium light, or lime light.

The evolution of light and heat in the combustion of bodies; combustion; state of ignition.

hich is ignited by the heat evolved by friction. -- Percussion fuze, a fuze in which the ignition is produced by a blow on some fulminating compound. -- Time fuze, a fuze adapted, either by its length or by the character of its composition, to burn a certain time before producing an explosion.

One who, or that which, produces ignition; especially, a contrivance for igniting the powder in a torpedo or the like. [Written also igniter.]

e charge is composed in the cylinder and is then exploded either by a flame of gas (flame ignition -- now little used), by a hot tube (tube ignition) or the like, by an electric spark (electric ignition, the usual method is gasoline engines, or by the heat of compression, as in the Diesel engine. Gas and oil engines ar…

einer's lamp, an apparatus for the instantaneous production of a flame by the spontaneous ignition of a jet of hydrogen on being led over platinum sponge; -- named after the German chemist Döbereiner, who invented it. Called also philosopher's lamp. -- Flameless lamp, an aphlogistic lamp. -- Lamp burner, the part of…

Being in a state of ignition; burning; having active properties; as, a live coal; live embers. " The live ether." Thomson.

suction into cylinder of explosive charge, as of gas and air; second stroke, compression, ignition, and explosion of this charge; third stroke (the working stroke), expansion of the gases; fourth stroke, expulsion of the products of combustion from the cylinder. This is the cycle invented by Beau de Rochas in 1862 and…

An apparatus for automatic ignition.

in a spray just before the end of the compression stroke and is fired without electrical ignition. The fuel is sprayed into an iron box (called a hot bulb or hot pot) opening into the combustion chamber, and heated for ignition by a blast-lamp until the engine is running, when it is, ordinarily, kept red hot by the he…

In internal-combustion engines with electric ignition, a plug, screwed into the cylinder head, having through it an insulated wire which is connected with the induction coil or magneto circuit on the outside, and forms, with another terminal on the base of the plug, a spark gap inside the cylinder.

The science which treats of poisons, their effects, antidotes, and recignition; also, a discourse or treatise on the science.
