Zusammenfassung:	A method or system to determine peak firing pressure of a cylinder of an engine having a crank shaft. The method includes accessing a knock signal received from a knock sensor of the cylinder. The method includes determining a location of peak firing pressure based at least in part on the knock signal. The location of peak firing pressure is associated with combustion of the engine and corresponds to a time or a crank angle of the crankshaft. The method includes generating an indication of the location of peak firing pressure. Il est décrit une méthode ou un système visant à établir la pression d'allumage maximum dun cylindre dans un moteur à vilebrequin. La méthode comprend laccès à un signal de cliquetis reçu de la part dun capteur de cliquetis du cylindre. La méthode comprend létablissement dun emplacement pour la pression d'allumage maximum en fonction du signal de cliquetis, et ce, du moins en partie. Lemplacement de la pression d'allumage maximum est associé à la combustion du moteur et correspond à un moment ou à un angle de manivelle du vilebrequin. La méthode comprend la génération dune indication de lemplacement de la pression d'allumage maximum.
