Modeling of HCCI Combustion: From 0D to 3D

The detailed chemical kinetics was implemented into the 0D single-zone model, 1D engine cycle model and 3D CFD model respectively. Both simulation and experiment were carried out on a four-stroke gasoline HCCI engine with direct injection. The 0D model (HRG) was developed to study the isolating effect of HCCI parameters. The 1D engine cycle model with HRG was established to study the gas exchange process and the direct injection strategy in the gasoline HCCI engine with two-stage direct injection (TSDI) and negative valve overlap (NVO). The 3D model with HRG was constructed to study the ignition control mechanism in "two-zone HCCI" combustion via analysis the auto-ignition spots distribution in combustion chamber. "Two-zone HCCI" is defined in this paper as premixed ultra-lean compression ignition combining with premixed ultra-rich compression ignition. The three models were validated by experiments. The simulated results provided a detailed insight into the processes governing combustion and pollutant formation in the HCCI engine. TSDI fuel strategy and two-zone HCCI combustion are adopted to resolve the two stubborn problems of HCCI ignition timing control and high load extension. Copyright © 2006 SAE International.
