Content
IN this investigation some of the underlying principles affecting the knocking characteristics of motor fuels in service have been studied. Briefly, the experiments indicate that the relative knocking characteristics of certain cracked gasolines with respect to straight-run gasolines may be affected by the relationship among spark timing, engine speed, and mixture ratio. From the standpoint of engine design the most advantageous combination of these variables in a given engine varies according to the nature of the fuel used.
It is suggested that some of the anomalous characteristics of benzol blends are the result of vaporization phenomena in the induction system, as also are certain “depreciation” effects which occasionally have been observed among straight-run gasolines containing tetraethyl lead.
