Abstract

In this study, the numerical calculation of the Homogeneous Charge Compression Ignition (hereafter HCCI) process is carried out by using Curran et al.'s DME elementary reaction model for DME fueled IICCI engine. On condition simulating shock tube, the validity of the DME elementary reaction model is investigated. And main elementary reactions releasing heat are investigated in case of multi-stage ignition. As a result, numerical calculation using Curran et al.'s elementary reaction model can qualitatively predict the influence of equivalence ratio, temperature and pressure on the appearance timings of low temperature reaction and high temperature reaction under the pressure and the temperature in HCCI engine.
