THIS paper is an analysis of the economic value of the use of high compression, from the viewpoints of fuel cost, carbon-removal cost and engine performance.
Charts and tables, based on ranges of fuel cost, compression ratio and cost of carbon removal, and on assumed increases in economy from the higher compression, are used to evaluate the economies that can be effected under these assumptions. The same methods can be applied with actual data to determine the economic value of a doped or improved fuel that makes high compression without detonation possible.
Methods are given also that will show the car designer what gains in power can be made by an increase in the compression. Attention is called to the fact that improvement in fuel economy under these conditions may not be so great as expected unless it is accompanied by a change in gear ratio.
In conclusion, the author argues for high compression as a means of conserving our resources of gasoline, which eventually will be exhausted in spite of unforeseen overproduction in the past.
