Les capteurs MAP, ou capteurs de pression absolue d'admission, sont des dispositifs qui mesurent le niveau de pression dans le collecteur d'admission d'un moteur et transmettent ces données à l'ECU (unité de commande du moteur) ou au système de gestion du moteur. L'ECU utilise les données de pression du capteur MAP pour calculer la densité de l'air entrant dans le moteur et, par conséquent, déterminer la quantité appropriée de carburant à injecter pour une combustion optimale. Cela contribue à optimiser les performances du moteur, l'efficacité énergétique et les émissions. Les capteurs MAP sont couramment utilisés dans les moteurs à essence et diesel, et ils sont particulièrement importants dans les moteurs à induction forcée (tels que les moteurs turbocompressés ou suralimentés) où la pression d'air d'admission peut varier considérablement par rapport à la pression atmosphérique.<\/p>\n
