THE SUNDAY. STAR, WASHINGTON, D.

Search for the cause of this ab- normal wear, automotive engineers reveals dirt, raw gasoline and eign atter as the principal factors. ordingly the motorist is ow being offered a wide variety of r cleaners, oil purifiers and recti- ers, gasoline strainers and various other devices for keeping the engine efficient So much effort was expended in the work of making engines run smooth 1y and perform remarkably that there was little opportunity to provide for a clean diet that would prolong life by reducing wear. But owners and engineers soon discovered that engine performance faded away after ten to twenty thousand miles of running and often could not be restored again There are still a lot of car owners who do not realize that even when they change the oil in the engine every 500 to 1,000 miles the dilution caused by raw gasoline passing the piston rings may be as high as 50 per cent.

How much of this dust remains in the cylinders to mix with the raw zaseline and stray oil to form a fine abrasive? There are various estimates, but the wise car owner appears to be taking no chances. He is astounded at the amount of air an engine breathes, and he does not have to be told that this air should be clean. This accounts for the keen interest n air-cleaners, there belng a number of different devices in use on cars or offered on the market. Some strain air just as the gasoline purifiers the fuel. Others beat out the es of dirt by the rotary method Others trick the dirt out of the air cither through centrifugal force or momentum.

Apparently it is not enough in the efficiency line to have the raw gasoline rectified from the crankcase and returned to the engine as fuel, as is done on one make. The engine of the near future must not even subject the pistons and cylinder walls to wear during those few eventful moments of start- ing. When the average engine starts there is a rush of raw gasoline to the cylinders. This is in the form of a spray and not so much trouble fol- lows if the engine happens to go off promptly. But after a stall or too and too much choking the vapor promptly condenses on the piston head and cylinder walls, leaks down past the rings and cleans off what- ever oil happens to be on the parts it This means that the next oments of the engine's life will be run off without sufficient lubri- cation. This has led to the adoption by several manufacturers of electrical pre-heating devices under various names. The theory in each case is to so vaporize this early spray that it will not readily condense when it strikes the cold cylinder walls. A double advantage is had by reason of the fact that the engine is much more likely to fire promptly on a more normal mixture. Seek Carbon Curb. Not content with cleaning the alr, straining the gasoline of impurities, rectifying the gasoline in the crank- case and purifying the oil in the crankcase, engineers have already turned their attention to the possibil- ity of automatically eliminating what- ever carbon forms in the engine. Re- gardless of the work of keeping the engine's diet free from foreign mat- ter, it is found that burning fuel means forming ashes. When gas vapor is burned carbon is the result. The less dirt there is in the engine the less opportunity there is for this residue to cling and thus to remain in the engine, but even in the clean- est of engines some of it remains. Thus there has come into use devices for feeding a little water or a little special oil to cylinders while the en- gine works. The idea is to loosen up any carbon that collects or to convert it into gas. And these devices that employ oil also aim to keep the valve stems from getting too dry or sticky, a function which does not come under the province of the oil purifier or the alr cleaner. With all of these devices and a little | intelligence in operating the car it is ! said that the average engine's life can be more than doubled. Carbon knocks vanish. There is no oil dilution, no | appreciable bearing wear, no piston | slaps, no valve grinding, no carbon cleaning, no loss of power, no difficul- ty in starting, no sticky valves, no oil pumping, cylinder réboring or piston ring replacement. Moreover, all of these devices can be added to the car for less than $100. More miles to the engine will mean more dollars in the car owner's pocket and more service from the average automobile. The opinion seems to be that the efficiency devices are going to be the rectifiers of car ownership and the custom cleaners, (Copyrisht, 1925.) Six ownership.

Silverplating the trimmings of an automobile may be done without the use of electric current, and in many cases without the removal of the part, by the use of a preparation which can easily be made. Nitrate of silver crystals are dis- solved in water until the water will dissolve no more. The solution is then changed into silver chiloride by the addition of strong salt water. The solution should be mixed in a glass vessel and on the addition of the salt water, the silver chloride will be pre- clpitated to the bottom. The silver chloride is separated by filtering through filter paper. The precipitate should be washed several e d OF VIRGINIA Hallt e Chariestg\\ r?“ 5 INCHESTER 4 Chantilly Centerville Gainesville = ROUTES TO THE SHENANDOAH VALLEY times by filtering with clear water and should then be allowed to dry thoroughly. When dry, the silver chloride is mixed with three parts (by weight) of fine salt and two parts of cream of tartar. To use, a cloth wet with water is dipped into the powder and applied to the parts to be plated. After the silver plating is formed, polishing ma: be done with chalk or whiting. An occasional application of the prepara- tion will keep the parts bright and new-looking in appearance. Autos Have Human Qualities. Automebiles are so human.

The Packard Motor Car Company believed that there was a sincere desire for Packard Now it has overwhelming proof of this desire. The average reduction of 3750 on the stand- ard Packard Six enclosed car models simply made possible the release of a vast, pent-up demand. This demand will continue to grow as more people learn the good news. * 5.Passenger Sedan, $2,585, at Detroit Delivered and Equipped, $2,880, Packard Washington Motor Car Company Open Weekday Evenings MAN WHQ , at Washington North 600 PACKARD OWNS ONE all centers of population of 5,000 Road Surfacing Speeded Up. ;e Surfacing of highways in the United | tem of approximately States is going forward at the rate of | - about 40,000 miles a year.
