Abstract-We propose an estimator of the combustion torque on a Diesel Engine using as only sensor the easily available instantaneous crankshaft angle speed. The observer consists in a Kalman filter designed on a physics-based time-varying model for the engine dynamics. Convergence is proven, using results from the literature by establishing the uniform controllability and observability properties of this periodic system. A test bench and development environment is presented. Performance is studied through simulations and real test bench experiments.

“…It is shown that there are only two harmonics of interest, the second and fourth cycle harmonic for a two cylinder engine, hence eliminating the need for storing numerous coefficients when calculating the DFT of the signal. Block angular acceleration measurements were also used for purposes of torque estimation in [23]; in addition four metrics were developed for misfire detection.…”

Résumé -Observateur cylindre à cylindre haute fréquence pour le contrôle des moteurs Diesel -Les normes de pollution de plus en plus rigoureuses ont imposé un large intérêt pour la réduction d'émissions. Deux stratégies peuvent être considérées : post-traitement et réduction d'émissions moteur. Pour les moteurs Diesel, le post-traitement a un coût élevé induit par la technologie et par le contrôle de ces systèmes. Dans ce contexte, le mode de combustion Highly Premixed Combustion (HPC) est devenu une source d'intérêt ces dernières années. Il représente une des voies les plus prometteuses pour la nouvelle génération des moteurs Diesel en utilisant des taux élevés de recirculation des gaz d'échappement (EGR). Des essais sur banc moteur ont apporté la preuve de la réduction significative d'émission. Cependant, l'application réelle sur véhicule implique le fonctionnement du moteur en transitoire qui est encore loin des essais en stabilisé au banc moteur. Plusieurs importants défis doivent être surmontés. Avec cette technologie de combustion, l'équilibrage de couple cylindre à cylindre est une nécessité. En effet, un léger déséquilibre entre les cylindres peut avoir des conséquences dramatiques et induire un bruit important, une possible extinction et des émissions polluantes plus élevées. Dans ce sens, nous développons des observateurs haute fréquence de la combustion. Ces derniers servent d'outils aux stratégies de contrôle temps réel. Abstract -High Frequency Individual Cylinder Estimation for Control of Diesel Engines -Increasingly stringent pollution regulations have spurred a broad interest in the reduction of engine emissions. Two strategies can be considered: after-treatment or engine emissions reduction. For Diesel engines, after-treatment has a high cost induced by the required technology and implementation issues. In this context, the Highly Premixed Combustion combustion mode (HPC) has emerged as a topic of major interest in recent years. It represents one of the most promising ways for new generation of CI engines using high Exhaust Gas
