Exploring and Modeling the Chemical Effect of a Cetane Booster Additive in a Low- Octane Gasoline Fuel
Novel combustion systems such as SACI (Spark Assisted Compression Ignition), GCI (Gasoline compression combustion) or lean combustion concepts are being developed for better performances. These combustion systems share a common objective : control the reactivity in order to have a proper combustion phasing and to lower emissions. Fuel additives have been used for decades to enhance combustion properties. However, their chemical effects is not fully understood especially when considering novel combustion systems. In order to evaluate the additive use approach, this study proposes a 0D simulation regarding the reactivity effect of a widely known diesel additive : 2-ethylhexylnitrate.
