Unburnt Mixture Auto-Ignition Prediction

Abstract

As it is commonly assumed that knock occurs because of local auto-ignition(s) in the unburnt mixture, Sections 2.1.2 and 2.3.2 the accurate prediction of auto-ignition is the key to developing a fully predictive knock model for the 0D/1D engine simulation. This chapter aims at better understanding the chemical processes resulting in auto-ignition and developing an appropriate approach for predicting the occurrence of this phenomenon.
