Abstract
A high gain non linear observer is implemented to estimate the enclosed mass in the combustion chamber of a spark ignited engine. The observer uses the cylinder pressure measurement during the compression and combustion strokes to estimate the enclosed mass. An engine model is proposed and used as a virtual engine to build the observer. The model is validated by comparison with real measurements, obtained from experimental tests. The results of the observer are compared with the virtual engine model.
