Abstract

A mathematical engine model is developed to study the operation process in Homogeneous Charge Compression Ignition (HCCI) engines. Ethanol is used as an alternative fuel for testing in this model. Two-step reaction mechanisms are implemented to model combustion process for which Arrhenius reaction rates are used and heat transfer process is also included. The simulation results are then compared with experimental data from a modified heavy-duty diesel engine which is used to imitate HCCI operation. Results from this model show good correlation with experiment with respect to combustion phasing, pressure rise and peak pressure. Some control strategies could be potentially developed to stabilize HCCI combustion based on this model. ©2005 AACC.
