Engines to Run on Heavy Oil Predicted for Near Future. The use of heavier liquid fuels for airplane and automobile engines was forecast in a paper delivered recently before the American Institute of Mining and Metallurgical Engineers by Charles J. Deegan, petroleum engineer of Ponca City, Okla. A leading automobile manufacturer bas on the verge of commercial success a Diesel engine for airplanes weighing only three pounds per horsepower, be declared. The fuel for this engine is a low gravity fuel oil, such as is now used for power purposes and heating. Mr. Deegan raised the question as t o what effect the successful use of such an engine in automobiles and airplanes would have on the demand for gasoline. On the other hand, some oil companies are introducing a light, natural gasoline selling a t a higher price than ordinary and capable of being used by both airplanes and automobiles. More fuel oil than gasoline is being used each day, despite the popular idea that gasoline is the principal product of the distillation of petroleum, Mr. Deegan pointed out. New types of internal combustion engines are likely, in his opinion, t o cause the refiners t o produce a larger number of different kinds of motor fuels in the future. Whereas only two or three grades of gasoline and one or two of Diesel oil are now manufactured, Mr. Deegan sees the future refinery output consisting of many kinds of internal combustion fuels ranging from very light gasoline t o a heavy distillate that approaches - the present fuel oil. Oil companies should spend immediately millions of dollars on chemical research for new products and new processes of refining necessary to meet future demands and provide outlets for the crude oil of future years, Mr. Deegan indicated.-Science Senice
