Show I DUMP WEATHER SPEEOSENGINE Conclusions Are Drawn That Feeding of Water Will Bring Smoothness Ever alncr the beginning of the pas rnKine industry optrators have ho-i ho-i i .-(I that on ilnmp days and nt nights i Kbn the air is more humid thnn dur-i dur-i ,,- the day, the engine runs better a nd .-it la more power on n given throttle ipenlng than it does on a dry day. At first son:- engineers said that the results were merely psychological . ,d that the humd I atmosphere could not cause nn Increase in power. Those r-ntltl.- doubters even offered proofs aZ the justice of their contentions, Which served to convince a good many people Mi VEX . KI B FN 1 : PITS. 5 lit the real facts arc there. Water in to the engine does increase the iO$rer. At the same time it has n jflndency to reduce carbon deposit, and under certain circumstances it Is likely iu remove a deposit of troublesome i rticles, though it cannot be said with certainty that it will remove hard c :rbon. It is common practice for operators i f kerosene engines to feed water into ifijg combustion chamber not only to -reduce the temperature because kerosene kero-sene engines are wont to heat rapidly, especially if poorly designed, but also tc get more power by permitting a nigh compression to he used. Peril.-, ps the general use of water 'n kerosene kero-sene engines led to the marketing by numerous manufacturers of devices designed to feed water or steam to : utomobilo engines In mnn eases I ; he device consists of a water tank v. :th piping to the Inlet manifold above the throttle. There Is a suitable control con-trol so that the water may bo shut qfl when desired. Any one who has used one of these devices knows immediately upon turning turn-ing on the water the engine speeds iip, though it is necessary to have the engine hot before turning on the wute: otherwise It will slow down or stop In some types then- is a line lesdln.i to the radiator flllci neck so the. moist air can be sucked into the car burctor. OX ALL TYPES. At an rate, regardless of the type of device, all of these designed to feed water or steam have a beneficial effect upon the engine, and their use Is Jus-litied Jus-litied both as a power Increaser and I carbon preventer Briefly stated the use of water results in a gain In ther-j n.al or heat efficiency by preventing the usual loss of heat through the water jacket at the beginning of the explosion stroke and giving back the1 heat later on in the stroke when the' power on the piston Is not so great. The automobile engine is a notorious) heat waster, though It is, strictly speaking, a heat engine and therefore 'should not waste any heat, or bolter,' i.F little ns possible. Yet fully one-third one-third of the heat generated (and the heat is power) is lost by being passed to the cooling water. HOLDS THE HEAT. When the water la spent into the, cylinders upon the InlaU' stroke the i unrge is naturallj cooled. On completion com-pletion it is heated .nd upon explosion explo-sion it is turned into steam, thereby inking away some of the heat which would ordlnaril) he wasted by passing through the water jacket into the water. Latei on In the power stroke- when the piston Is reduced the steam gives up Its heat in greater part and thus helps put some more power when1 u Is needed. In the explosion stroke the water prevents a heat loss by taking tak-ing some of the heat Into the mixture only to give up later when the heat is needed in the cylinder. This explanation may bo taken as being correct with the theory as to water decomposition wrong. The theory the-ory assumes that the water present during the explosion Is decomposed into its elements, oxygen and hydrogen, hydro-gen, ind that the presence Of the oxy-gen oxy-gen makes it possible for free carbon to combine with it. thus effecting per-jfect per-jfect combustion There is no proof I of this, though it may be possible that water does decompose to some extent I at high pressure and at the high tem-porature tem-porature which obtains in automobile engine cylinders. DAMP WEATHER RESULTS. However the matter Ifl explained, the fact remains that the use of the water is beneficial and the apparent magic which gives the engine more power em n damp d:i 1m something iieal. "As to the carbon removing abll-lly abll-lly of the water, there Is somethig to be said. Surely a caked deposit cannot be removed b water or steam unless by luck Many owners have said that tru use of Water Stopped prc-ii.nlti.on prc-ii.nlti.on and knocking, and verj llki I this is true, because the water may lave removed the small particles of I carbon, which became Incandescent land caused pre-lgnltion, which In turn caused the knocking It also is possi- ble for the water to prevent carbon from depositing In an quantity which lit would do under normal conditions. The owner who doubts the ability of the water to increase the power of his engine should not try to prove it by pouring a quart or so Into the car-Iburetar car-Iburetar Intake and Interfere with the rurhuretor by tcmporarll stopping the gas flow at the nozzle, but he Bhould feed It above the throttle, so that the water enters with the. mixture. nn |
