A highly volatile mixture of fluid hydrocarbons, obtained from petroleum, as also by the distillation of bituminous coal. It is used in making air gas, and in giving illuminating power to water gas. See Carburetor.

A kind of internal-combustion engine; -- in British countries called usually petrol engine.

In gasoline-engine motor vehicles, the cooling of the cylinder by increasing its radiating surface by means of ribs or radiators, and placing it so that it is exposed to a current of air. Cf. Water cooling. -- Air"-cooled`, a.

A system (devised by Henri Pieper, a Belgian) of driving automobiles employing a gasoline engine and an auxiliary reversible dynamo. When there is an excess of power the dynamo is driven by the engine so as to charge a small storage battery; when there is a deficiency of power the dynamo reverses and acts as an auxilia…

usually propelled by internal combustion engines (using volatile inflammable liquids, as gasoline or petrol, alcohol, naphtha, etc.), steam engines, or electric motors. The power of the driving motor varies from about 4 to 50 H. P. for ordinary vehicles, ranging from the run-about to the touring car, up to as high as…

cs; -- called also petroleum spirit, petroleum benzine. Varieties or similar products are gasoline, naphtha, rhigolene, ligroin, etc.

r gas is carbureted, as by passing it through a light petroleum oil. The carburetor for a gasoline engine is usually either a surface carburetor, or a float, float-feed, or spray, carburetor. In the former air is charged by being passed over the surface of gasoline. In the latter a fine spray of gasoline is drawn from…

See Gasoline.

team- engine boiler. The gas used may be a fixed gas, or one derived from alcohol, ether, gasoline (petrol), naphtha, oil (petroleum), etc. There are three main classes: (1) gas engines proper, using fixed gases, as coal, blast-furnace, or producer gas; (2) engines using the vapor of a volatile fluid, as the typical ga…

tillate obtained in the refinement of petroleum which is intermediate between the lighter gasoline and the heavier benzine, and has a specific gravity of about 0.7, -- used as a solvent for varnishes, as a carburetant, illuminant, etc.

nd properties. It is refined by distillation, and the products include kerosene, benzine, gasoline, paraffin, etc. Petroleum spirit, a volatile liquid obtained in the distillation of crude petroleum at a temperature of 170° Fahr., or below. The term is rather loosely applied to a considerable range of products, includi…
