Show ECONOMIZE USE OFJASOLINE ' Economical operation with a Blx cylinder car, or in fact any car. may be said to be attained when about 14 miles on one gallon of gasoline is the average over a fairly long period in the use of that car." says John F. McLain "Gasoline economy is but one of the many economics that can and should be worked lor on a car It I is possible but very seldom obtained : by the average man, no matter what car he owns. This merely indicates I that he has not the knowledge of th different things that go to make up economical use of gasoline. "In general, if one understood the combustion of fuel in the cylinder he would have all that Is necessary to unJer3tand economical operation He should know that a cr-rtain amount of fuel, and this will practically in every ev-ery cue be gasoline, requires air mixed mix-ed with il In order to have It burn and thus produce power It is necessar.. that if should have the correct amoutu of air, althcupii a little excess of air dees very little harm It Is necessary in order to have economical operation that each Cylinder have a correct mix tnre. and this problem Is one of dis tnbution. If a perfect mixture were made In the carburetor distribution would be ensy, but In general today il is a mechanical mixture of gaso line and air, and the correct distribu tici of this is nol easy." |
