Abstract: a b s t r a c tAutoignition of an initially quiescent stratified layer of n-heptane and air is numerically studied using multistep kinetic mechanisms. The influence of the level of stratification on the ignition characteristics of the mixture is investigated. The pressure and temperature conditions selected are relevant to compression-ignited internal combustion engines. As previously reported, for uniform temperature conditions, ignition always occurs in fuel-rich regions whereas the stable flame is located …
