Beschreibung
Zusammenfassung:	There is described an internal combustion engine (1) including: - a crankcase (2) comprising one or more cylinders (CY), - a head (3) arranged atop said crankcase (2) and comprising a flow module (4) and a cam carrier module (5), the cam carrier module (5) being arranged atop said flow module (4), said flow module (4) comprising one or more inlet conduits and one or more exhaust conduits, wherein at least one inlet conduit and at least one exhaust conduit are associated with a respective cylinder (CY), - a blow-by recovery circuit (B1, B2, B3) through which fluid communication is established between the crankcase (2), the flow module (4) and the cam carrier module (5), wherein at least one of said crankcase (2) and cam carrier module (5) comprises at least one access port (8, 9, P2) in fluid communication with said blow-by recovery circuit, a sensor assembly (10; 10') comprising a cap (12; 12') fixed at the access port (8, 9, P2) and including an installation seat (13,; 13') for a pressure sensor (15) within which a reading channel (14) is provided, the reading channel (14) having a first end (A) arranged at the access port (8, 9, P2) and a second end (B) at which the pressure sensor (15) is received, wherein the second end (B) of the reading channel (14) is arranged at a higher geometrical elevation than the first end (A) of the reading channel. L'invention concerne un moteur à combustion interne (1) comprenant : un carter de vilebrequin (2) comportant un ou plusieurs cylindres (CY) ; une tête (3) agencée sur ledit carter de vilebrequin (2) et comprenant un module d'écoulement (4) et un module de support de came (5), le module de support de came (5) étant agencé sur ledit module d'écoulement (4), ledit module d'écoulement (4) comportant un ou plusieurs conduits d'admission et un ou plusieurs conduits d'échappement, au moins un conduit d'admission et au moins un conduit d'échappement étant associés à un cylindre respectif (CY) ; un circuit de récupération de fuite de gaz (B1, B2, B3) à travers lequel une communication fluidique est établie entre le carter de vilebrequin (2), le module d'écoulement (4) et le module de support de came (5), ledit carter de vilebrequin (2) et/ou ledit module de support de came (5) comportant au moins un orifice d'accès (8, 9, P2) en communication fluidique avec ledit circuit de récupération de fuite de gaz, un ensemble capteur (10 ; 10') comportant un capuchon (12 ; 12') fixé à l'orifice d'accès (8, 9, P2) et un siège d'instal
