| YOU WANT quiet~powerful~economical operation of your motor! A continuous supply of clean, undiluted oil assured by the KINGSTON OIL AERATOR & FILTER will give you this result DIRTY, DILUTED OIL MAIN CAUSE OF ENGINE TROUBLES:—Oil quickly becomes contaminated. Grit and sand are inhaled along with the air that enters the motor through the carburetor and crank case breather. Particles of metal, from the rubbing of moving parts, and carbon, from overheating the diluted oil, also accumulate. The oil is instantly diluted when starting by the “choking” made necessary by present day fuel. This dilution continues as long as the motor is running. Water dilution and acid, natural products of combustion, are additional agencies in destroying the motor. They cause rust. THE EFFECT:—More good motors are ruined by dirty, diluted oil than all other causes combined. This is the real reason car manufacturers demand that oil be changed every 500 miles or less. It is common knowledge that frequent changing of oil does not eliminate this destructive menace. THE REMEDY:—The Kingston Oil-Aerator and Filter performs the two important functions signified by its name—the removal of gasoline, water and acid dilution from the lubricating oil by heat treatment and aeration, and the removal of grit, sand, metal and carbon abrasives by filtration and precipitation. It operates by the suction of the motor, through a connection to the intake manifold. The device is entirely independent of the existing lubricating system and does not change the functioning of the latter in any manner. AERATION:—Gasoline, kerosene, water and sulfurous acids will evaporate when exposed to the atmosphere. If they are subjected to a strong draft of air, they evaporate many times faster—still more rapidly if they are heated to an appreciable extent. This is known as aeration or forced evaporation. In the operation of the Kingston Oil-Aerator and Filter, the dirty-diluted oil is first heated in the heating element (No. 2) to a temperature approximating 200 degrees Fahrenheit or the boiling point of water under vacuum. The oil then passes through pipe (No. 4) into the aerating chamber, where it is violently agitated by a submerged draft of cold air that vaporizes and absorbs the particles of gasoline, water and acid. The vapor-laden air is then drawn by the suction of the motor through pipe (No. 3) to the engine cylinders, where it is burned with the charge. The oil in the aerating chamber can only escape through the transfer valve and the air displacing the vacuum must enter the aerating chamber through this same opening, therefore, the outward flow of oil is violently resisted by the inrushing air. Thus, by direct contact with the air, all of the oil passing through the system (approximately three to five gallons per hour) is aerated and relieved of the destructive diluents. FILTRATION AND PRECIPITATION:—Abrasive substances such as dirt, sand, metal, carbon, etc., are heavier than oil, hence can be separated either by filtration or precipitation. Due to the varying viscosities of motor lubricants and different operating conditions, it is well known that a proper combination of both methods is more effective than either alone. This is the combination used in the Kingston Oil-Aerator and Filter and years of experience have found it to be the most efficient construction possible. After aeration, as described above, the oil is transferred to the lower or filtering chamber. Here the aerated oil flows by gravity, through the filter to the return pipe; all the grit, sand, carbon and the metal particles are separated from the oil by the filter and caused to settle to the bottom of the chamber. The foreign matter is easily drained out by opening the drain plug at the bottom of the Filter. INSTALLATION:—Anyone can easily attach the Kingston Oil Aerator & Filter within an hour’s time. Each device is furnished with complete fittings. Illustrated instructions show exact location and method of attaching each connection, as is indicated by the illustration at the left. Special fittings are furnished to facilitate installation on 28 prominent makes of cars—all other cars, trucks and tractors may be easily equipped with our general installation outfit. COST:—The price for the device complete varies from $15.00 to $20.00. The labor charge for installation averages $2.50; for this small amount, you can obtain utmost motor protection and can enjoy the comfort of knowing that your motor is at all times operating under ideal conditions. YOUR CAR DEALER will gladly attach the Kingston Oil Aerator & Filter because he knows you will be greatly benefitted by its use and thereby naturally become a greater booster for the car he sells. | ||
