The mixture requirements of an internal combustion engine at various speeds and loads

Abstract

Valuable information on the steady-running mixture requirements of an internal combustion engine, as affected by speed and load, is contained in the report of the classic experiment conducted by Messrs, O.C. Berry and C.S. Kegerreis at the Engineering Experiment Station, Purdue University, in 1920. Since that time many advances have been made in the field of the internal combustion engine, both in engine and accessory design and in operating procedure. Gasoline fuels have been improved and considerably standardized. There is now available much more information on the nature, causes and effects of detonation than is 1920. It was therefore deemed appropriate to check the conclusion of these experiments using a modern automobile engine and possible more accurate equipment.
