The Knock Severity Index – A Proposal for a Knock Classification Method

Abstract
A knock severity index has been proposed which is based on the pressure jump during knock and on the fraction of mixture charge involved. The index can be applied to compare the knock severity in different engines under various conditions without the restrictions imposed by earlier methods of classification. To determine the knock severity, the mixture properties as well as the relevant cylinder process have to be known. The cylinder process can be measured by the application of digital equipment.
