A& roads ave neither level nor straight, the eves of an ap proaching driver may occupy almost any position in the patte thrown by the lamps. hence quate lighting is possible that w at times cause glare.

On all roads where touring speeds pre safe very little light is needed or desirable on the road surface within 30 10 100 feet, hut when meeting other vehicles bright fllumination is needed in this area and on the shoul der and right-hand side of the road. This makes 11 imperative that practi cally no light should be projected above the horizontal at any time, and the driver, in self-protection, is forced to depress his own lights. thus auto matically protecting the other driver from glare The safety feature might be en hanced by arranging the system so that switching from one adjustment tn the other would be accomplished hy pressure of the left foot of the aperator. the depressed beam being the one in nse except when the driver hoids the button down. % Fine: %1045 12595 Detroit, plus revenus tax needs to | the |, low enough to avoid | 4| haust strokes. the 20,000,000 or mq No. 163—Firing Orders. “I wonder,” | cleaned the spark plu happen if these ignition { hooked up wrong."” | “Youd have a scrambled engine,” I told him How's th different says his mine, vet it’s a six, tov.” | “You can't have a different ss you also change the open. e of the "nderstand, ating that you could not run vour engine if vou happened to fire it in a different order.

In order to explain it to him it was necessary to go back to some fundamentals.

There is one eight in production that fires like twin-fours, and a twin-six that is no | longer manufactured was a_twin for You could run it on either set of viinders. If you disconnected all the ignition wires on one block of a conventional V-eight you would find that the engine wouldn't perform at all. It all depends upon timing.” Smith wanted to know whether the power of a motor was a matter of timing. “Power is due to many factors,” 1 explained. “In the old days they used from | firing | > in using | other members of the motor clan. ! to think that the size of the cylinders t, but with racing motors c-inch displacement now | doing more than a hundred miles an | hour as an average speed, every one | has a different idea about it.

This explains the popularity wf the eights, the straight elghts having the advantage of great- er simplicity than the V-type. . An- other thing that contributes to power is freedom from vibration at high en- gine speed. This brings in your tim- ing feature. “The better the engine is timed the smoother it will run and the higher speed it will attain without vibration and excessive friction losses. If you are familiar with the different firing orders vou'll understand that as yet nothing approximating an it as to what's what in tim- g. livery engineer seems to have his own ideas. Firing Orders Vary. “One popular six fives 1, 4, 2; 6, 3, 5, starting with the cylinder next to the radiator. Most of the other sixes fire 1, 5, 3, 6,2, 4 Bear in mind, of course, that these firing orders are closely linked tip with the timing of the valves, which is a matter entirely too complicated for backyard discus- sfon. “One popular four fires 1, 2, 4, 3, while another fires 1, 3, 4, 2.’ The lat- ter arrangement seems to be preferred by the manufacturers of improved four-cylinder engines. “In the eights the variation is sur- prising. Offhand I know of nine dif- | ferent methods of firing eights, and they are found on popular makes of cars at that. The order 1, 6, 2, 5, §, 3, 7, 4, seems to be the most popular th the designers of straight eights. ine makes use that order. To give you an idea of how differ- ent the orders are, let me show you this list:" Smith found one straight eight fir- ing 5, 4, 8, 7, 2, 1, while another fired 1,'3,'2.'5.'8," 6, 7. 4. The latter zives ome of the oddest-sounding hausts of any automobile. Of three popular V-eights he found as many combinations of orders. What amazed him was to think that anything appearing so haphazard could be the result of such painstak- | ing thought and precision.

WASHINGTON, 300000 CARS SEEN IN 4 YEAR iHead of Pittsburgh Experi- | ment Station Revives Prob- | lem of Saturation. Since that elephantine child of American industrial genius, the auto- mobile, was a toddling infant, it has been the pleasure of thousands of ob- servers to discuss ‘‘the saturation point.” Of late, however, this illusive “point” has been rather lost to sight in the most terrific wave of buying in the history of the industry. It has remained for Dr. A. C. Field- ner, head of the Pittsburgh Experi- ment Station of the United States Bureau of Mine, to revive the disous- slon. Fieldner assumes the satu- ration ratio of passenger cars to be one car for every four persons in the country. In a recent address in Philadelphla he declared that auto- mobile registration, on this basis, will level off {n 1932. "After that, he he- lleves, any further increase will be due to population growth. - Sees 31,000,000 Total. The total number of automobile engines in this country will reach 31,000,000 in 1930, Dr. Fieldner esti- mates, or double the number in use in 1925. Another 50 per cent will be added in the course of the next 20 years, bringing the total of 1950 up to 45,000,000 Terming-an adequate motor fuel supply a national necessity this au- thority went on to say. ““Production thus far has more than kept pace with the growing demand and recent improvements in ‘crack- ling' have made it possible to crack any type of cruce ofl to gasoline, coke and gas. Present trends in the auto- motive and petroleum industry, in our opinion, are in harmony with predic- tions that petroleum will continue to furnish the great bulk of automotive fuel during the next decade.” Utopian Promjises. Utopian promises for the future of petroleum are held out by Prof. James K. Norris, president of the American Chemical Society, who pre- dicts that the motorist of the future will come to depend on the products of petroleum for everything connected with his car except the metal frame work. For example the rubber will come from diolefine gases, obtained from the crackling of crude petroleum. Unbreakable glass for the wind- shields and windows will also come from petroleum products. To allay the fears of those whe see rapid diminution of the supply from nature, the eventual conversion of Vegetation into petroleum was pre- dicted. NEW JACKS SUPERIOR. Latest Equipment Keeps Clothes Clean From Low Cars. Careful use of the latest jack equip- ment for automobiles will prove their superiority over the old type if only in the matter of keeping the user's clothes cleaner. Balloon tires and lower hodies have brought the rotary jack with its long handle to the front in most tool equipment. g/t Performanc Within Reach of Thousa For many years, those pay top prices for motoring luxury have bought eight- cylinder cars as a matter of course.

OCTOBER 24 1926—PART 3. v, BODIES WORTHY OF THE VELIE Did you ever own an automobile that grew old before its time be- cause the body was cheaply built? You will never have that experi- ence with a Velie. Every Velie body is built compléte in the great Velie plantand is worthy, in every particular, of America’s Long- Life Car. Both wood and steel are used in Velie bodies — for no other combination of materials will give the quality that Velie must have. The frame-work is built of the finest hard wood that the mar- kets of the world afford—every inch of it cured to Velie’s exact- ing standards. All joints are fitted VELIE MOTORS Washingt to the finest limits known to the wood-workers’ craft. And overthis rigid frame is fitted an armor of sheet steel that has been especially treated for strength and finish. The frame-work of wood makes it possible to finish the interior as g;utifully and substantially as the finest hand-built furniture— and eliminates the possibility of “closed car rumble.” See the various Velie body types in the salesroom of the nearest Velie dealer. And bear in mind as you inspect them dlha; tll:e}r beauty is permanent — that their individuality will be as striking in years to come as it is today. CORP., Moline, IIL on Veile Co. NORRIS H.
