A Basis for Understanding Antiknock Action 570046

THIS paper analyzes ignition-delay data and knocking characteristics of fuels. An approach to the problems of fuel sensitivity and engine severity has been made by attempting to relate the properties of the fuel-air mixture as shown from ignition-delay data and the temperatures and pressures reached by the compressed gases in an engine.
The relation between octane numbers and ignition-delay characteristics of the fuels is examined.
Antiknock properties of tel are investigated. It is shown that the amount of antiknock effectiveness is related to the amount of tel decomposed.
