Cylinder pressure signals contain valuable information for closed loop engine control. For using this information low-cost cylinder pressure sensors with high long-term stability have been developed and are starting to be installed into production engines [1,2,3,4].This paper presents new algorithms to estimate cylinder air mass, to control exhaust gas recirculation and to estimate the air-fuel ratio distribution between different cylinders of a SI engine. The proposed control algorithms avoid additional calibration expense by using adaptive, model based control strategies and learning feed-forward control. They have been implemented on a dSPACE rapid control prototyping system [5] and have been evaluated through studies using a 1.0 liter 3 cylinder SI engine on a dynamic engine test stand.
