Abstract	Advanced control systems and diagnosis algorithms for modern automotive engines need further feedback information of different events inside the cylinders. In this work, we propose a new method for in cylinder trapped mass estimation (TME), using instantaneous cylinder pressure measurements as input. The method is based on a graphical signatures generation tool, recently proposed for diagnosis and parametric estimation of nonlinear systems. A two dimensional graphical signature is generated from measured cylinder pressure. It is shown that generated signature is correlated with the value of trapped mass and thus enables us to design an TM estimator. Experimental Data obtained on a four cylinder diesel engine test bench has been used for off line static validation. The proposed method has been successfully implemented and tested on line using LTC Diesel vehicle.
