diesel engine modeling, optimal control


A dynamic heavy-duty Euro 6 diesel engine model for energy optimal control is developed. The modeling focus is on accuracy in the entire engine operating range, with attention to the region of highest efficiency and physically plausible extrapolation. The effect of the air-to-fuel ratio on combustion efficiency is studied, and it is demonstrated how this influences the energy optimal transient control. A convenient, physics-based, method for pressure sensor bias estimation is also presented.
