Abstract

L’invention concerne un ensemble moteur suralimenté comprenant un moteur, une ligne (1) d’admission d’air reliée à ce moteur, un compresseur (4) d’air et un refroidisseur (5) de l’air issu du compresseur (4), des moyens de détermination de la perte de charge nominale à travers le refroidisseur (5), caractérisé en ce qu’il comprend de plus un régulateur PID de la pression d’air de suralimentation agencé pour recevoir en entrée une consigne de pression d’air de suralimentation ainsi qu’une mesure de pression d’air de suralimentation et pour fournir en sortie une consigne de pression d’air de suralimentation corrigée, des moyens de calcul électronique agencés pour détecter un fonctionnement stabilisé en pression d’air de suralimentation, relever la valeur du terme intégral du régulateur PID lorsqu’un tel fonctionnement en stabilisé est détecté, conclure à une formation de glace dans le refroidisseur (5) lorsque la valeur du terme intégral est supérieure à un seuil indicatif d’une présence de glace. Figure 1The invention relates to a supercharged engine assembly comprising an engine, an air intake line (1) connected to this engine, an air compressor (4) and a cooler (5) of the air coming from the compressor ( 4), means for determining the nominal pressure loss across the cooler (5), characterized in that it further comprises a PID regulator of the charge air pressure arranged to receive a pressure setpoint as input of charge air as well as a measurement of charge air pressure and to provide at output a corrected charge air pressure setpoint, electronic calculation means arranged to detect stabilized operation at air pressure of supercharging, note the value of the integral term of the PID regulator when such stabilized operation is detected, conclude that there is ice formation in the cooler (5) when the value of the integral term is greater than a threshold indicative of the presence of ice.
