ABSTRACT:
A system and method for controlling an engine involves providing a model for volumetric efficiency. The model recognizes that volumetric efficiency (VE) has stronger dependency on intake pressure than on exhaust pressure. The model allows tuning of the relative importance of intake pressure to exhaust pressure, specifically, by reducing the relative importance of the exhaust pressure to intake pressure in the composite volumetric efficiency load variable. The model provides for a calculation where the exhaust pressure term of the engine pressure ratio is de-rated through the use of an exponent less than one.
