Abstract

L'invention concerne un moteur (28) à combustion interne comprenant un compresseur (14) amont et une turbine (18) aval et un conduit (32) de prélèvement d'air dans le compresseur (14) et de réinjection de cet air dans la turbine (18). Selon l'invention, le conduit (32) comprend des moyens de piégeage (30) de particules, notamment des grains de sable ou des poussières, contenues dans le flux d'air.The invention relates to an internal combustion engine (28) comprising an upstream compressor (14) and a downstream turbine (18) and a duct (32) for taking air from the compressor (14) and re-injecting this air into the compressor (14). the turbine (18). According to the invention, the duct (32) comprises means (30) for trapping particles, in particular grains of sand or dust, contained in the air flow.
