A vertical water space in a fire box or combustion chamber.

A four-stroke cycle for internal-combustion engines consisting of the following operations: First stroke, 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…

ce, or supply; to the end; completely; hence, in, or into, a condition of extinction, exhaustion, completion; as, the fuel, or the fire, has burned out. "Hear me out." Dryden. Deceitiful men shall not live out half their days. Ps. iv. 23. When the butt is out, we will drink water. Shak.

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

hemical properties, or those which are conditioned by affinity and composition; thus, combustion, explosion, and certain solutions are reactions occasioned by chemical properties. Chemical properties are identical when there is identity of composition and structure, and change according as the composition changes. 3. O…

body, and is attended with irregularly recurring chills, fever, profuse sweating, and exhaustion.

A kind of empyreumatic oil produced by the combustion of textures of hemp, linen, or cotton in a copper vessel, -- formerly used as a remedial agent. Dunglison.

An engine, usually an internal-combustion engine of a certain type (the radial type) having several cylinders arranged radially like the spokes of a complete wheel. The semiradial engine has radiating cylinders on only one side of the crank shaft.

An action included by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.

.), a furnace having a regenerator in which gas used for fuel, and air for supporting combustion, are heated; a Siemens furnace.

ceedings. -- Return flue, in a steam boiler, a flue which conducts flame or gases of combustion in a direction contrary to their previous movement in another flue. -- Return pipe (Steam Heating), a pipe by which water of condensation from a heater or radiator is conveyed back toward the boiler.

ted through the air by the force arising from the expansion of the gases liberated by combustion of the composition. Rockets are used as projectiles for various purposes, for signals, and also for pyrotechnic display.

The quality or state of being seedy, shabby, or worn out; a state of wretchedness or exhaustion. [Colloq.] G. Eliot. What is called seedness, after a debauch, is a plain proof that nature has been outraged. J. S. Blackie.

electricity, compressed air, a spring, or an explosive gas), attached to an internal- combustion engine, as on an automobile, and used as a means of starting the engine without cranking it by hand.

Designating an internal-combustion engine of a type resembling the Diesel engine in using as fuel heavy oil which is injected 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…

e audible respiration, especially as the result or involuntary expression of fatigue, exhaustion, grief, sorrow, or the like.

The muffler of an internal-combustion engine.

To burn and smoke without flame; to waste away by a slow and supressed combustion. The smoldering dust did round about him smoke. Spenser.

A black substance formed by combustion, or disengaged from fuel in the process of combustion, which rises in fine particles, and adheres to the sides of the chimney or pipe conveying the smoke; strictly, the fine powder, consisting chiefly of carbon, which colors smoke, and which is the result of imperfect combustion.…
