Title (EN) SYSTEM AND METHOD FOR ENHANCED ENGINE MONITORING AND PROTECTION
(FR) SYSTEME ET PROCEDE POUR UNE SURVEILLANCE ET UNE PROTECTION AMELIOREES DU MOTEUR
Abstract:
(EN) A system and method for monitoring and controlling an engine (12) based on an engine fluid pressure include sensing and engine fluid pressure, determining a current value for an engine operating parameter, determining whether the engine fluid pressure has crossed a first threshold corresponding to the current value of the engine operating parameter, determining whether the engine fluid pressure has crossed a second threshold corresponding to the current value of the engine operating parameter, generating a warning signal when the fluid pressure has crossed the first threshold but has not crossed the second threshold, and generating a shutdown signal when the fluid pressure has crossed the second threshold. In one embodiment, the second threshold is determined based on the first threshold by applying a constant offset value.
(FR) L'invention concerne un système et un procédé de surveillance et de commande d'un moteur (12) basés sur la pression d'un fluide du moteur. Ledit procédé consiste à détecter la pression d'un fluide moteur, à déterminer une valeur courante caractéristique d'un paramètre de fonctionnement du moteur, à déterminer si la pression dudit fluide moteur dépasse un premier seuil correspondant à la valeur courante du paramètre de fonctionnement du moteur, à déterminer si la pression du fluide moteur dépasse un second seuil correspondant à la valeur courante du paramètre de fonctionnement du moteur, à générer un signal d'avertissement lorsque la pression du fluide dépasse le premier seuil mais pas le second ; et à générer un signal d'arrêt lorsque la pression du fluide dépasse le second seuil. Selon un mode de réalisation, le second seuil est déterminé en fonction du premier seuil, par application d'une valeur de décalage constante.
