HCCI bustion can not only ensure both the high economic and dynamic quality of the engine, but also efficiently reduce the NOx and smoke emission. Moreover, one of the remarkable characteristics of HCCI bustion is that the ignition and bustion process are controlled by the chemical kinetics, so the HCCI ignition time can vary significantly with the changes of engine configuration parameters and operating conditions. In this work numerical scheme for the ignition and bustion process of DME homogeneous charge pression ignition is studied. The detailed reaction mechanism of DME proposed by American Lawrence Livermore National Laboratory (LLNL) and the HCT chemical kinetics code developed by LLNL are used to investigate the ignition and bustion processes of an HCCI engine fueled with DME. The new kinetic mechanism for DME consists of 79 species and 。為考慮壁面?zhèn)鳠岬挠绊?，在HCT程序中增加了壁面?zhèn)鳠嶙幽Ｐ汀? 2009（機(jī)材B0921） 指導(dǎo)教師 郭艷艷
