Empirical investigation and control-oriented modeling of n-butanol HCCI for improving combustion controllability

Engines operating in homogeneous charge compression ignition exhibit high thermal efficiencies and ultra-low emissions; however, the lack of effective control over combustion timing prevents practical engine application. In this work, experiments are performed to address the combustion control challenges, and a control-oriented, physics-based combustion model is developed using the first law of thermodynamics and semi-empirical correlations to …
