THE AMERICAN public demands that, in safety, comfort, appearance, speed, acceleration and deceleration, motorcoaches shall compare favorably with the present-day automobile, according to the author. These demands have resulted in a substantial increase in weight that has required the use of much larger engines, and this has brought about a tremendous increase in fuel consumption. Since fuel costs represent a large percentage of the total cost of operation, the possibility of decreasing these expenditures is receiving considerable attention. In addition, and apart from the increase in fuel usage resulting, taxation is causing grave concern.The author describes the fuel issue as it now exists in the United States. Data are submitted showing the tax situation, costs and refining operations, the potential saving assuming the employment of the less volatile fuels, their possible method of employment, advantages, disadvantages and the like. The data concerning prices of crudes and their derivatives were obtained from accredited sources.3After outlining the commercial situation, the author analyzes the uses of the crudes and discusses their derivatives. The cracking process is described and the determination of costs and of losses is commented upon, together with costs at the sources. The Diesel system, hot carburetion and cold carburetion, as means of employing the less volatile fuels in internal-combustion engines, are analyzed separately and compared. Statements are made concerning the use of kerosene as a fuel and the criticism is made by the author that the term kerosene does not designate a definite product and that the specifications are of too wide a range to permit determination of the suitability of any such fuels when used in connection with present-day heavy-duty motorcoach engines. After summarizing the paper, the author concludes that the available evidence concerning the crudes and their derivatives points to the fact that we have no alternative other than to continue the use of our present fuel standard, namely, gasoline, in spite of hopes to the contrary.
