Abstract

L'invention concerne un moteur à combustion interne comprenant au moins quatre cylindres et un système d'échappement. Un carter de turbine comportant une roue de turbine d'un turbocompresseur à gaz d'échappement est disposé dans le système d'échappement, et une installation d'épuration de gaz d'échappement est agencée dans le sens d'écoulement du gaz d'échappement derrière le carter de turbine. Un premier tuyau d'échappement bifurque entre le moteur à combustion interne et le carter de turbine de manière à guider les gaz d'échappement et rejoint à nouveau le système d'échappement en aval de l'installation d'épuration de gaz d'échappement. Le turbocompresseur à gaz d'échappement se présente sous la forme d'un turbocompresseur à gaz d'échappement « Twin Scroll », au moins deux cylindres correspondant à une séquence d'allumage du moteur à combustion interne étant regroupés pour former un ensemble cylindre. Un premier ensemble cylindre est relié à une première volute d'entrée de manière à guider les gaz d'échappement par l'intermédiaire d'un deuxième tuyau de gaz d'échappement, et un deuxième ensemble cylindre est relié à une deuxième volute d'entrée de manière à guider les gaz d'échappement par l'intermédiaire d'un troisième tuyau de gaz d'échappement, le premier tuyau de gaz d'échappement pouvant être relié au deuxième et au troisième tuyau de gaz d'échappement de manière à guider les gaz d'échappement. La configuration selon l'invention permet d'atteindre des puissances spécifiques plus élevées pour le moteur à combustion interne tout en assurant une protection thermique des composants.
