Abstract
L'invention comporte un groupe moteur composé d'un moteur diesel 1 et d'un turbo-compresseur 2 réunis par un circuit de circulation d'air comportant un conduit de dérivation 12 en parallèle avec le moteur 1, dans lequel sont montés une soupape de réglage de débit 20 et un échangeur de chaleur 13 parcouru par les gaz d'échappement de la turbine de façon à élever la température du gaz traversant le conduit de dérivation avant de se mélanger aux gaz d'échappement du moteur. Le dispositif permet d'etendre la gamme de vitesses utiles de fonctionnement du moteur et d'améliorer la consommation de carburant aux faibles vitesses.The invention comprises an engine unit composed of a diesel engine 1 and a turbo-compressor 2 joined together by an air circulation circuit comprising a bypass duct 12 in parallel with the engine 1, in which a valve is mounted. flow control valve 20 and a heat exchanger 13 through which the exhaust gases from the turbine pass so as to raise the temperature of the gas passing through the bypass duct before mixing with the engine exhaust gases. The device makes it possible to extend the range of useful operating speeds of the engine and to improve fuel consumption at low speeds.
