Abstract

L'invention porte sur un détecteur de la pression intérieure d'un cylindre de moteur diesel de construction simple, de grande efficacité, de faible encombrement et de grande précision, et sur son mode d'utilisation. Un détecteur de pression (2) est placé dans une bougie de réchauffage (3) entre la partie chauffante en céramique (4) de la bougie (3) et son élément de fixation (6). De cette manière, le détecteur de pression (2) détecte directement les déplacements de la partie chauffante en céramique (4) sous l'effet de la pression intérieure au cylindre et détecte ainsi la pression intérieure de ce dernier. La précision de détection peut ainsi être largement plus élevée que celle des détecteurs usuels de ce genre qui détectent les déformations élastiques de la culasse, à partir desquelles on détecte indirectement la pression intérieure du cylindre. Le détecteur (2) étant placé à l'intérieur de la bougie (3) de réchauffage, on peut économiser de l'espace et le fil conducteur n'est pas exposé à l'extérieur de la bougie. Cela permet d'améliorer l'efficacité de fonctionnement et d'empêcher la rupture du fil.
