An engine (100) provided with a variable series supercharging system (7) composed of a high-pressure supercharger (10) and a low-pressure supercharger (20), a supercharging pressure sensor (63) for detecting the pressure of intake air pressurized by the variable series supercharging system (7), a high-pressure supercharger rotation sensor (61) for detecting the rotational speed of the high-pressure supercharger (10), a variable actuator (14) for adjusting the capacity of the high-pressure supercharger (10), and a control device (60) capable of controlling the variable actuator (14).  The control device (60) controls the variable actuator (14) based on detection signals from the supercharging pressure sensor (63) and the high-pressure supercharger rotation sensor (61). L'invention concerne un moteur (100) muni d'un système (7) de suralimentation variable en série composé d'un compresseur haute pression (10) et d'un compresseur basse pression (20), d'un capteur (63) de pression de suralimentation servant à détecter la pression d'air d'admission pressurisé par le système (7) de suralimentation variable en série, un capteur (61) de rotation du compresseur haute pression servant à détecter la vitesse de rotation du compresseur haute pression (10), un actionneur variable (14) servant à régler la capacité du compresseur haute pression (10) et un dispositif (60) de commande capable de commander l'actionneur variable (14).  Le dispositif (60) de commande assure la commande de l'actionneur variable (14) sur la base de signaux de détection provenant du capteur (63) de pression de suralimentation et du capteur (61) de rotation du compresseur haute pression.
