Sammanfattning

To facilitate model-based control of combustion timing and work output in Homogeneous Charge Compression Ignition (HCCI) engines, a cycle-resolved model of HCCI incorporating cylinder wall temperature dynamics is presented. Heat transfer between the in-cylinder charge and the cylinder walls is important for explaining HCCI cycle-to-cycle behaviour but is rarely included in control-oriented models. The model is calibrated and verified using experimental data from an optical engine allowing measurements of the wall temperature to be made. The model captures the behaviour of the studied outputs as well as the evolution of the cylinder wall temperature during load changes.
