Abstract

A mathematical engine model is developed in this thesis to study the operation process in Homogeneous Charge Compression Ignition (HCCI) engines. Ethanol, an alternative fuel, is chosen for testing in this model. Two-step reaction mechanisms are implemented to model combustion process for which Arrhenius reaction rates are used. The simulation results are then compared with experimental data from a modified heavy-duty diesel engine. Results from this model show good correlation with experiment with respect to combustion phasing, pressure rise and peak pressure. Based on this model, a controller could be synthesized to keep HCCI ignition at a minimum advance for best torque value under static and dynamic conditions, unaffected under process noise such as varying temperature, pressure, etc.Dept. of Mechanical, Automotive, and Materials Engineering.
