Abstract

Homogeneous Charge Compression Ignition (HCCI) combustion is a pioneer method of combustion in which
pre-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. HCCI engines can operate
with most alternative fuels, especially, dimethyl ether (DME) which has been tested as a possible diesel fuel due to
its simultaneously low NOx and PM emissions. In this paper a single zone detailed chemistry combustion model for
determining the time evolution of the homogenous reacting gas mixture in the combustion chamber and performance
characteristics of the engine has been developed. The aim of this paper is to analyse the effect of intake temperature
and EGR on the characteristics of auto-ignition and operating window of the HCCI combustion considering knock
and misfire boundaries.
