HCCI Engine Modeling for Real-Time Implementation and Control Development

A propane-fueled homogeneous charge compression ignition (HCCI) engine model has been developed for the development of new engine control strategies in which a single-zone combustion mathematical model is adopted. The model has a reasonably simple structure and is implemented in a SIMULINK environment for simulation studies. The results of simulation studies show that the model can provide information on autoignition timing, engine work output, gas temperature, and concentrations of in-cylinder species. Model validation has been conducted by comparing the simulated output with experimental results obtained from a single-cylinder HCCI research engine. The comparison shows a fair agreement between the simulation and experimental results.
