OF THE CARBURETOR. Practically all engines, steam, hot air, or gas, are heat engines, that is, they depend upor. the generation of heat for their power or energy. In the ateam engine the heat is generated externally, under a boiler, perhaps a great dlatanca away from the engine, the heat being carried to the engine in the steam. The gas engine, often called an Internal combustion engine, has the heat generated Inside of the engine itself. The heat in both cases is generated by the combustion, or burning, of the fuel. What is combustion, or what happen when a fuel burnsT' A chemical action takes place, or. In the case of a gaa, tha hydrogen which la In It chemically combines with tha oxygen cf the air to mak water, which is composed of two parts of hydrogen to ono of oxygen; and the carbon In the gas also combines with tha oxygen of the sir, but makes carbon dioxide. which la composed of one part of carbon to two parts of oxygen. When such a chemical action takes place heat Is generated. . In the steam engine the burning of the coal, also made up of carbon and hydrogen, is comparatively slow, but In the gas engine the combustion, or generation of heat, is instantaneous, or there is an explosion. An explosion Is an Instantaneous combustion. The speed and method of using the to the burning the due of heat power of the fuel In the gaa engln la such is that this explosion absolutely necessary In order to use the jnost of the heat generated. If the combustion were alow most of the heat would ascap without giving out Its energy or power. From the above we aee that tha fuel (In the auto engine, gasoline) must be gotten Into the cylinders of the engine in such a condition as to explode the moment It is ignited. This means two things; namely, that It must enter the cylinders in the form of gas or, at nlost, a fine mist, and that It must be mixed with the property quantity of oxygen, or. as the oxygen of the air is used, proper The function of the quantities of air. carburetor is to accomplish these two things Before studying the action of the carburetor let us see what the properties of gasoline, which can be utilized in the design of the carburetor, are: ACTION ' The liquid gasoline will change to a gaa if It la brought to a certain tempera- -ture, approximately 70 degree Fahrenhelt, when under atmospheric pressure, when just as water changes to steam brought to a temperature of 213 degrees. If the steam comes in contact with a surface of air colder than 213 degress it will condens and again form water. Likewise, if the .gasoline gas comas In contact with a cold surface It will condense and agdtn form a liquid. The pressure of the air at sea-lev- 5 'ft at an even lower temperature, ports which la used In tha design of the carburetor. Some carburetors depend entirely upon the above action, but In most carburetors the vaporising is facilitated by having lb gasoline enter the mixing chamber and Inlet manifold in tha form of a spray For this purpose a spray noszle is used In the Illustration' the noXkle la shown as B- Tha gasoline in the float cham pressure ber(A) is underC atmospheric la a partial vacuum but thw space when tha englna is running. Thus the pressure at B is less than at A and so the gasoline will be squirted or sprayed out of the nozzle, where it will change to a gas. Ax the gasoline sprays out of the nos sle air will enter at D and so mix wtth the vaporised gasoline.

Thu by adjusting the naedle E the mount of gas to air can be regulated and so tha mixture be made to be in the proper ratio for an instantaneous combustion. The speed and power of the engine Is controlled by means of the throttle R. If this be wide open a large amount of the mixture will enter the cylinders and tha explosion will be very powerful, while of it be partly dosed a limited amount of mixture will enter the cylinders and the engine will not be very powerful and will run slowly. The opening of the nozzle B should of an inch above the about level of the liquid in the float chamber A. If less tha mixture will be too weak in gasoline, while If more it will be too rich, and possibly will drop out when the engine is idle. The carburetor float and float valve will maintain this level, and they are properly set when the carburetor leaves the factory. Never tamper with thla setting. Sometimes, however, the float will leak, if of metal, or become saturated with gasoline If of cork, and so become too heavy. This will result in too high a level and possibly dripping. Tha leaky float can ba soldered, while the cork float must be dried and - coated with hellao. The float valva mechanism will sometimes stick, causing either a too high or too low level. the proportion of the Unfortunately gas to air will not ba constant for all angina speeds, the mixture becoming richer at the higher speeds. To bring tha mixture back to the proper portion, the auxiliary air valva H la furnished. This will open at the high speeds automatically If sufficient air does not enter at , As ft is practically impossible to have the tension' of the spring of thla auxiliary air valve ao as to give a correct mixture for all speeds, most carburetors have an extra regulating device for the higher speeds. This device generally Is operated by the throttle lever and acta on tha nozxla needle.

You will note that I said that the gasoline will change to a gas at about 70 degress, when under atmospheric pressure. It will change to a gas, or vaporise, at a much lowar temperature if the pressure be less than atmospheric, or if there be a Partial vacuum, which is practically the am thing. It is this property of the gasoline to vaporlx at so comparatively low a temperature, added to tha fact that the suction of the engine piston makes a vacuum in the cylinder.

His time was 5 hours 17 minutes 30.79 seconds, an average of 94 48 miles an hour, against the old record of 6 33:65 61, or 89.84 miles an hour, made by Da Palma in 1916.

Inveetlgxtlons covering a long period of years have proven that uniformity in tire eervloa is 15 per cent attributable to variations In, road conditions and 35 per cent due to manufacture. Tires vary In mileage in about tha same way that the workmen .building them do In their work. The same rules apply In the materials entering into tha tira. Rubber varies like apples To build a uniform tire that will give uniform service it is necessary to eliminate these variables and establish a positive basis from which to work. There is the tgsk of training men to be uniform workmen. Fabric must meat a certain uniform standard of quality. The cotton fibre must ba long staple. Scientific records are necessary. Thera is also constant laboratory testing. Not a single change may ba adopted without months of road testing. Cord tira sales during 1921 amounted to about 20 per cent of ail tires sold. This 7,000.000 tires of all sizes represent a remarkable proportion of tha total when one considers tha conditions that had to he encountered.
