Laminar Burning Velocity Model and Combustion Simulation of Dimethyl Carbonate / Iso-octane Mixture

Abstract

Carbon-neutral fuels have been studied in order to reduce the Well to Wheel CO₂ emissions from vehicles equipped with ICEs. In order to apply carbon-neutral fuels to existing engines, it is necessary to control the combustion pattern of carbon-neutral fuels. In this study, a detailed chemical reaction model of dimethyl carbonate (DMC), one of the carbon-neutral fuels, was developed. We obtained a laminar burning velocity model which can simulate the combustion characteristics in the initial stage of combustion in an engine cylinder. This combustion model was introduced into a three-dimensional combustion simulation, and the calculated cylinder pressures were validated by comparison with experimental data.
