Title

Hcci Engine Modeling Of Diisopropyl Ketone, A Prototypical Biofuel

Abstract

In the current study, modeling of diisopropyl ketone (DIPK) HCCI engine experiments from Sandia [1] is conducted with single-zone engine model using CHEMKIN PRO[2]. The adiabatic single-zone HCCI model is explored. In this manner, the single-zone model gives accurate compressed-gas pressures and temperatures, allowing the ability of the kinetic model to predict autoignition timing to be well evaluated. Although ignition timing can be investigated using the single-zone model, the heat release rate in HCCI engines is largely controlled by charge non-uniformities. Since the charge in the Sandia HCCI engine was well premixed for these experiments, the heat-release rate is mainly affected by temperature non-uniformities resulting from heat transfer and turbulent convection. Discussion is provided on the validity of the DIPK model in comparison with the parametric engine data over a range of temperature, pressure, equivalence ratio and engine speed.
