Improved Experimental Agreement of Ionization and Pressure Peak Location by Adding a Dynamical NO-Model

Improved Experimental Agreement of Ionization and Pressure Peak Location by Adding a Dynamical NO-Model

Modelling combustion engines is an important tool in engine research. Development and modelling of ionization current has potential in developing virtual pressure sensors based on ionization measurements. Previous models has problem when predicting the true relationshipbetween the pressure peak loca...
