Abstract:
(EN) In a method for operating an exhaust-gas-turbocharged internal combustion engine (10), wherein auxiliary gas compressed by an auxiliary compressor (22) is supplied to the exhaust gas of the internal combustion engine upstream of the exhaust-gas turbine (20) of the exhaust-gas turbocharger (18), the temperature of the fluid flow that passes through the exhaust-gas turbine (20) is equal to or lower than the temperature of the exhaust gas upstream of the supply of the auxiliary gas.
(FR) L'invention concerne un procédé permettant de faire fonctionner un moteur à combustion interne (10) à turbocompresseur à gaz d'échappement, selon lequel un gaz d'appoint comprimé par un compresseur additionnel (22) est acheminé dans les gaz d'échappement du moteur à combustion interne en amont de la turbine à gaz d'échappement (20) du turbocompresseur à gaz d'échappement (18), ce procédé étant caractérisé en ce que la température du flux de fluide traversant la turbine à gaz d'échappement (20) est égale ou inférieure à la température des gaz d'échappement avant l'acheminement du gaz d'appoint.
(DE) Bei einem Verfahren zum Betreiben einer abgasturboaufgeladenen Brennkraftmaschine (10), wobei dem Abgas der Brennkraftmaschine strömungsoberhalb der Abgasturbine (20) des Abgasturboladers (18) von einem Zusatzverdichter (22) verdichtetes Zusatzgas zugeführt wird, ist die Temperatur der die Abgasturbine (20) durchströmenden Fluidströmung gleich oder kleiner als die Temperatur des Abgases vor Zuführung des Zusatzgases.
