8 f " THE SUNDAY OR EGO XI AN, PORTLAND. JLVY 9, 1920 RAS-PRG IE LIKELY TO SHOW INCREASE Auto Drivers Interested in Saving Fuel Bills. RICH MIXTURE COSTLY Every Possible Caxe Should Be Taken to Insure Proper Igni-- ". tlon and Motor Repair. There is every indication that In the coming summer we are going- to have a period of high prices in the Kasoline field. Understand, there is no shortage of motor fuel; there is plenty to go around, but the producers seem to feel that they are justified in rais ing prices, and unless all signs fail they are going to do it- This being so. every car owner in America is vitally interested In saving all the fuel that he possibly can. We have been ex tremely wasteful of our fuel in the past and the wise motorist will wel come suggestions that will enable him to eliminate waste of all kinds and thereby reduce his mounting bills. Here the principal leaks take place, and these must be stopped before real fuel efficiency can be hoped for. It is rather amusing to see ambitious car owners Install certain types of devices in connection with the carburetion system, when if they only knew how to adjust the carburetor properly nothing of the sort would be neces sary. -The modern internal combustion en gine will operate on a fuel mixture ranging from eight parts of air to one of gasoline to 14 parts of air to one of gasoline. Operating conditions, however, are better when, the mixture , , . .. - . ... . . 11 1 .athpr is leaner. iaai ia iw ' 1 w . than 8 to 1. But as a general rule car owners tend to use a mixture nearer the latter than the lormer. Don't Have It Too Rich. Obviously a mixture at 8 to 1 con tains almost twice as much gas as one t 14 to 1. If the engine ran better with the richer mixture there might be some excuse for . using it, but it doesn't. Further, the richer mixture tends to produce rapid carbonization, and while the engine will assimilate it. nevertheless the action ife sluggish and lacks the snap that is present with the leaner ranges. Therefore the first thing the car wner who aims at maximum effi ciency should do is to make sure that his carburetor is properly adjusted to give the leanest mixture consistent with satisfactory running. If the car owner Is unable to make this simple adjustment himself he should certain ly have the service station do it for him. In cases where the carburetor Is an old instrument with not enough range of air volume it may be wise to install one of the devices of the auxiliary air inlet type. These are inexpensive and easily put in," place. At any rate, every car owner should give his earn est attention to-the carburetion sys tem with a view to reducing the very probable waste in' this locality. Before we leave the carburetion sys tem we may suggest that many mod ern cars will satisfactorily operate on a mixture of gasoline and kerosene. If the individual owner will try this ex periment, using, say, four gallons of gasoline to one of kerosene, he may be pleasantly surprised, at any rate it ia worth-the attempt. This is particu larly so in warm weather, when this heavier mixture vaporizes more read ily. Keep Battery Filled. Now the carburetion may be never ho good, but if the ignition is not up to the mark maximum efficiency can never be reached. Therefore it be hooves the car owner to keep the bat tery fully charged and filled with dis tilled water, as ho has been warned id often to do. The cable connections at plugs and ignition unit and coil must be kept clean and tight. It does not one atom of good to get a fine ex plosive charge in the cylinders unless there is. a good hot spark to ignite it. These two items of carburetion and ignition may be termed the major 'Offensives in the campaign to get fuel economy; there are still numbers of machine-gun nests to be cleaned up before you have reached perfection. There are many places in the fuel sys tem where leaks may develop, and a direct leak-in the fuel line is a pro digious waster of gasoline. Moreover, a small leak is hard to detect; if the car owner has noticed a sudden increase in the amount of gas oline used, this may be the cause. At a 11 J ' " Hi, 1 L a t ' I'll.

It will be remarkable hpw much better the engine runs- after the fuel line has been cleaned out to give an unobstructed flow to the gasoline. After this the muffler will probablj be the better for a little attention A , clogged muffler consumes power thai ought to be employed In driving thh car. - - ; : '. Carbon Wastes Fuel. Another fruitful source of fuel waste is carbon in the cylinders. A carbonized engine uses much more fuel than a clean one. Scrape the-. cyl inders as one-of the first skirmishes in the fuel reduction campaign. In some instances, where an engine is an excessive carbonizer. it may be well to install one of the water feed ing devices or vaporizers, of which there are scores on the market, after " the .cylinders have -been thoroughly cleaned of all carbon deposits. These devices will prevent the formation of carbon In clean -cylinders, though-. I doubt that they will remove heavy deposits without assistance. The valve system must be in excel lent working order . or heavy fuel waste may result. The valves must seat properly or they will let the fuel mixture leak out without, performing its appointed function or only partly YOUNG THOMAS AND ELIZABETH -QUITE AGREE WITH THEIR MOTHER THAT THEIR NEW KING EIGHT IS A THOROUGHGOING CAR. A - ' Sixrfy?:; : 4k Mrs. Hoy T. Bishop of 4.15 Wouro street especially likes this Kins; because: of Its nirift, sure power and the ease with which It Is handled. She has driven several cars before this one. Mrs. Bishop Is the wife of Roy T. Bishop, head of the Oregon Worsted Mill at Sellwood. Incidentally. In this Industry, Portland has the only worsted mill west of Cleveland, O. It Is running; at present ViVs hours per dny and at that Is behind In filling; tfs orders. Its worsted yarns go to many -parts of the country and bring; dollars back to Oregon. at best. Any car owner who has ex perienced the pleasure of driving im mediately after the valves have, been ground will need no advice in regard to having the valves ground 'at fre quent intervals. Have you ever stopped to realize that every waste of power is really a waste of gasoline. If gasoline is ex ploded and the power so generated is wasted or only partly used this amounts practically to waste of fuel. If lubrication is not kept up to the mark the friction between moving, parts wastes power. Therefore be par ticular to lubricate -all parts of the mechanism as indicated on the chart or in the instruction book given with the car. The clutch, while it is usually a well behaved piece of mechanism, when it develops trouble is an enormous pow er and hence fuel waster.- When the clutch slips it is letting power slip away,- not to mention the damage to the part itself and the unsatisfactory action of the car. Misaligned wheels are another trou ble that results in wasted power and fuel. When the wheels are running out of true a scraping is set up be tween the tire and the road, which not only tears the tire to pieces in a short time, but also wastes fuel. It is the only wise plan to have "the wheel alignment checked ug twice a year, and oftener if the" car has suf fered a severe bump or for any. other reason the owner suspects that the wheels are out of line. In connection with the wheels, a dragging brake will materially increase the consump tion of power. It is so easy to adjust modern , braking aystems that there is no excuse 'for letting these parts re main in a condition that ia bad for them and worse for the general oper ation of the car. Finally, the car owner can save a great deal of fuel by careful operation of his vehicle. He' should learn to coast wherever possible, shutting off the ignition on long hills, with the throttle closed. Useless idling of the engine costs many thousands of gallons of fuel in the course of the year in this country. Do not waste fuel around the garage for washing parts, etc. Kerosene does Just as welt as gasoline, for washing metal parts and it is not so valuable today as gasoline.'

High school pupils of the country are to be given an opportunity to compete for a four-year university scholarship to be awarded for th.e best essay submitted in connection with Ship by Truck - Good Roads week. May 17-22, according to an announcement made last week, which said that the essays will be read and the prizes awarded by judges to be appointed by the federal bureau of education. The contest, it is said, is for the purpose of focusing public attention on the necessity for good- roads and the feasibility of the motor truck as a short haul medium. According to plans approved by Commissioner of Education P. P. Claxton. contestants, to be eligible to compete for the national prize, first must have won one of the prizes to be awarded by various organisa tions and individuals in their re epective communities. The national prize is to be known as the H. S. Firestone Uunlverslty scholarship and will be given. in any college or uni versity chosen by the winner. All high school pupils may submit a 500 word .essay, which must be entitled "Ship by Truck and Good Roads." but if the national prize is won by any pupil other than a" senior the award will be deferred until the win ner is ready to matriculate at the institution of his choice. ; Judges who will make the national award will be named by Commis sioner Claxton before. May . 22, by which time all essays must , be sub mitted. School superintendents and principals of high schools are being acquainted this week with the terms of the contest, and, it is expected, more than 1,000.000 essays will be written upon this subject, serving to accentuate the interest and to widen- the scope of discussion to be created by Ship by Truck-Good Roads week, during which time the cara vans of motor trucks will tour every section of the country. - - Organizations whose members are lending the weight of their influ ence and- activities - toward making the week a success include the Amer ican Automobile association, the United States chamber of commerce, the -American Automobile chamber of commerce, the national, grange, the ship by truck bureau, the army, the navy, and churches and- schools gen erally." State - superintendents of ,instruc tlon are being requested to direct the contest within their commonwealth. Prizes are to be awarded in each community and will be .determined by local committees. LOSS ' OF POWER TOO GREAT Clogged MulTler AVill Reduce Effi- V.. ciency, of Auto Engine. According to a writer in the cur rent issue of American Motorist, there are a- number of causes which -con-tribute to power losses in an engine. not the least of which is a partially stopped up or clogged muffler. It is natural that the often narrow and tortuous passages of the muffler should be choked with carbon after a year's use, he says, but very often remarkable improvement in engine efficiency is secured with no greater trouble than a temporary cleaning of the muffler, which should be beaten with a wooden mallet or a piece of wood; this will loosen the worst ac cumulations, which will then be blown out through the tail pipe. If the car is equipped with a muffler cutout and there is a noticeable difference in power when the cutout is closed and open, a cleaning of the muffler.'as- in dicated, should be undertaken at once.

COLUMBIA IS GAS SAVER AUTOMATIC TIIERMOST.VjP CON TROLS EXGIXE HEAT. - Device Declared to Be as Errcctive In Summer a In Winter In -Saving or Fuel. Every motorist has heard so much about saving gasoline in '"winter., that the advisability of saving It in sum mer has been .somewhat: overlooked. Yet it is possible to save -gasoline-on even the hottest days -of-'iuramcr, es pecially in starting t he car, - - "- " "The application -of the- thermostat to the motor car makes gasoline sav ing in summer time possible," says A. M. Beaver. "The Columbia car. for instance, has- a powerful thermostat which automatically opens and closes the radiator shutters with which this car is equipped. When the engine is cold the- shutters . are closed "This cuts off the air from. 'the engine, which -in- turn -warms up - more quickly than if the radiator is with out shutters, letting the fan send back a full stream. of air. "The beauty of this feature is its effectiveness' in winter. On the cold est days expensive hood covers are unnecessary and the engine warms up quickly to the most efficient running temperature. "This efficient running temperature is about 180 degrees, considerably more than the temperature of the hot test days of summer. Suppose the temperature is 90. That of the en gine before starting would also be about 90. perhaps a little less. The engine then would have to be warmed up to 180 degrees. Ths more quickly this is done the less gasoline waste. "And with the - price of gasoline going up from time to time, every pint saved is money in the pocket of the car owner. That is just what the thermostat and shutters on the Co lumbia do."

Jay walking pedestrians, whose nervous 'feet-Impel them to take a chance with the untamed taxi and the wild motor cycle, must' observe a brand new set of traffic rules in San Francisco. Jay walking will be forbidden. But the most important rule of all is that affecting pedestrian and vehicular traffic at cross streets. Under no circumstances must a pe destrian attempt to cross even at an official crossing unless the traffic cop toots his whistle. And even after the cop toots the pedestrian must not attempt to cross the street ahead of the traffic man. The traffic cop must lead the crowd like the pled piper led the children. If a pedestrian becomes too - gay witK . the new rule and forges ahead to hang up a record for speed,- he is very apt to find himself in police court the next morning.. Here's the way the new rule works: The traffic, cop will take a long breath and wind his klaxon for traffic, afoot and awheel, to proceed north and south. Then he, the cop, will take his place at the head of the parade and move northerly with it. After depositing pedestrian traffic on the protecting curb of the opposite sidewalk, the traffic cop will return to the center of the street. Then he will take another breath, sound his horn once more and lead the pedestrian procession west to east, after which ke will return to his post. Then the traffic cop will sound his siren once again, this time signifying that traffic is to move south from north, and lead the pe destrians to the southerly curb and ,n Fine Tire Making : . . - ; The reason you are interested in the name on your tire i that it identifies the maker.
