Lethbridge Herald (Newspaper) - March 30, 1918, Lethbridge, Alberta PAW TF.S rmi urrtutmtxuR tu�.v tmiuut Talk on Lubricating the Tractor (By V. E.

The !"> percent energy is then marie n-o of as follows; { 35^-loss through -~>rcloss through unburned gasses. 2.")Tr loss through frli-tiou. l-*>1r power delivered. The above figures are startling, but have been scientifically worked out , and prciven^to be correct. However | we will see if anything can be done � to reduce this S5 percent loss. j Heat is power, and we know there is a tremendous amount of heat thrown K through the radiator and circulating system of an internal combustion engine, but up to the present no invention has been made to avoid this radiation, in fact if it were nofrfor this j radiation the intense heat at the point of explosion, often as high as oOOO degrees F.. would in a very fe.w mfnutes reduce the cylinder and'piston to a mass of molten metal: so under present construction there is nothing we can do to reduce this I035. � Next we come to the 25 percent loss 1 through energy and unburned gasses. j You will find by removing the exhaust Upipe there is a tremendous amount of i power passes through the exhaust 1 valve, which with the present construc-' tion cannot be utilized and it is also � impossible to reclaim the unburned ; gasses that pass through _the-exhaust,:  jo we will have to pass tip asvjmpos-' j sible reducing this less of unburned-' 'gasses. . - We now come to the loss of 25 percent through friction. Friction is a great power destroyer and friction is' everywhere present in the moving parts of ti>e intern*! rombuMtoa et>-sin� Hat by proper l�bri�-*tloa "frie-t'.on" ti� .1 certain extent can bo re-dnet-v!. aiul the '.eagth of senrioo of your easine increa^eO. S.el u* for a few minute* consider the amount of friction of the. piston. This eusrine tl.ll.Ci is a tw>t cylinder, fevir ryel�� type with a t">lj bore S inch stroke. The piston tnnst be fitted to the cylinder very tUcht to hold the compression feet per minute. Imagine the amount of friction produced by these two surface* travelling at tha't rate of speed* To reduce this friction a film of "oil .005 of an inch thick must remain constantly between these two surfaces under conditions that are most incomprehensible; With a temperature in the combustion chamber ranging fw>m 300 to oOn* degrees F.. this film of oil not only reduces this friction but with tlir piston rinsrs must seal the compression in the explosion chamber on the compression stroke and at the titne of explosion hold the expanding passes so that the power is delivered to the crank from which it is delivered to the other parts o! the tractor. This temperature of 3000 degrees F.. is produced in the combustion chamber 150 times per minute. The greater part of this heat is carried off through radiation and the exhftust. but as iron is a good conductor of heat a portion of it is absorbed by the piston and cylinder walls; this film of oil must withstand this tremendous heat and yet retain a body sufficient to keep the surfaces of the piston and cylinder from coming in contact. .As to the composition of an oil that, will withstand this tremendous strain I will not attempt to discuss: in fact I could not if 1 so wished. But there are a few properties that an oil must have to do this work that we can consider. ' First, a gasoline or kerosene engine cylinder oil, must have a certain "viscosity" at working temperature tv Viscosity is best explained as "adhesion"' and "cohesion." Adhesion means that the oil must have certain proper-ties that will make it stick to surfaces of the piston and cylinder and-keen "them from .'coming in contact and increasing ' friction. ; ^Cohesion* that an oil most/have certain properties, that will make it stick together tc seal the explosion chamber. Remember these properties must be =0* t�!K* t�M oi\ Ia* * I c*mla �t>�Hp�i!y **� &tai �t wfc*� itvi-1 h>uc\t And b* �urv th�� �i\ yt>u bay hi* * the pr�>p*r �*ohe�Kin ,�nd �dhe�ion Alt **rMus t*mp*ratur*�. [ Sts-oact. lutvraai >-i>;�bu�:K\n wnittne i cylinder oil n�u�: hAv�\ certain' hf*t I And erajvration tests to Bi��> e(fiel�nt ] lubrlc*t:i>�, these te.��s are wh�t U | known a* "fljuh test" and "fire test." 1 "Flash �e*:" miMn.i the temperature j at which an oil will jclw oft s�sso.i I that will Ignite when the blase of a I Uper or match Is applied to the sur-} fac* of the oil. I Fir* test means that temperature at j which an oil will entirely burn up or' b�> citnsumetl. These are two very important properties a good cylinder oil must have; If an oil has a slash point below the working conditions of the engine It will flash or evaporate and leave the balance increased in viscosity, gummy etc.. will luerewse friction and require an abnormal amount of oil to keep the cylinders lubricated. "Fire test" is probably the most important test of a cylinder oil; In the movement of the piston through the cylinder backward and forward or up and down as the case may be there is a certain amount of oil that works � by the piston rings and into the com-� bustion chamber, this oiP should burn at the next explosion and leave little { or no deposit on the piston or cylinder walls; If the oil has too high fire test it will not burn ami will leave it deposit and on the intake stroko this deposit will gather and condense par-ticals of the generated gasses, which at the tline of explosion will not explode but will burn and will leave a deposit of carbon which will accuml-late at each succeeding explosion ami in time cause the engine to knock, deteriorate the generated fuel and in time necessitate the grinding of valves and a general cleaning of the cylinder and piston. 1 will not go farther into the reducing of the 25 percent loss in friction. However I believe by proper lubrication and care of an engine this loss may be reduced; if only - percent it means an addition to your 15 percent "power delivered" that will justify a careful selection of oils and taking good care of your tractor. In procuring the proper oil for the cylinder as well as the external part3 of your engine it is impossible for y3u to make these tests necessary to determining what oils is best and will meet working conditions. My advice is. not to buy your oils from the "fly in the night" salesman that comes to your place with a long story of tests, carbonless, etc.. but to get your oil from a reputable firm that have made these tests both in a laboratory and under working conditions and who you tHNtt* ���t*4 *�Jt mm* tat ***** *r�i At* rw�MM--�t*4�a �.r Mi* MM*h��- ta v-o�ct�*kMk js>�i fe*v� b��ft fitttel spwn tit prv*lav�. prvKlvv�>> m taer�*#e prvductKiu fix^JUluH.
