THE purpose of this paper is, first, to set down the methods which have been considered in the effort to develop a gasoline-type engine which will operate satisfactorily on non-volatile fuels, such as furnace or heating oil:
Second, to describe briefly commercial examples of the use of these various methods:
Third, to analyze the possibilities of these several processes with regard to power and efficiency, comparing them-as well as the results to be expected from the use of motor gasoline-with those of an engine operating on aviation gasoline as a basic standard.
Mr. Dutcher concludes that there are cases where horsepower hours per dollar's worth of fuel can be just as-or more-important than horsepower per pound of engine.
A further conclusion is that while the method used in the Appendix calculations is simple and the correction factors may be somewhat modified in the event that more accurate data should become available, it will be seen to give results which agree rather well with test records.
