Influence of Compression Speed on HCCI Ignition and Combustion 2011-01-1779
In HCCI Engine, the HCCI combustion characteristics come under the influence of change of compression speed corresponding to the engine speed. The purpose of this study is to investigate mechanism of influence of engine speed on HCCI combustion characteristics by using numerical analysis. At first, the influence of engine speed was showed. And then, in order to clarify the mechanism of influence of engine speed, results of kinetic computations were analyzed to investigate the elementary reaction path for heat release at transient temperatures by using contribution matrix.
