Title (EN) EGR DISPENSING SYSTEM IN IC ENGINE
(FR) SYSTEME DE DISTRIBUTION RGE POUR MOTEUR A COMBUSTION INTERNE
Abstract:
(EN) An EGR dispensing system is described which comprises a reciprocating piston internal combustion engine (l00)having exhaust and intake ducts (22,24) , a rotary gas exchanger having a housing (14) containing a rotating matrix (10) , and first and second sets of entry and exit ducts in the housing (14) . The first set of entry and exit ducts forms part of the engine exhaust duct (22,221) connecting an engine exhaust gas stream from the engine (100) through the housing (14) and matrix (10) to the ambient atmosphere . The second set of entry and exit ducts (22, 241) forms part of the engine intake duct connecting an engine intake air stream from the ambient atmosphere through the housing (14) and matrix (10) to the engine (100) . The matrix (10) is rotated at a sufficient speed for a substantial volumetric gas exchange to occur between the engine exhaust gas stream and the intake air stream.
(FR) La présente invention concerne un système de distribution RGE comprenant un moteur à combustion interne à piston alternatif (100) ayant des conduits d'échappement et d'admission (22, 24), un échangeur de gaz rotatif ayant un logement (14) contenant une matrice rotative (10), et un premier et second ensemble de conduits d'entrée et de sortie dans le logement (14). Le premier ensemble de conduits d'entrée et de sortie fait partie du conduit d'échappement du moteur (22, 221) envoyant dans l'air ambiant un flux de gaz d'échappement du moteur provenant du moteur (100) et passant dans le logement (14) et la matrice (10). Le second ensemble de conduits d'entrée et de sortie (22, 241) fait partie du conduit d'admission du moteur envoyant au moteur un flux d'air d'admission du moteur provenant de l'air ambiant et passant dans le logement (14) et la matrice (10). La matrice (10) est entraînée en rotation à une vitesse suffisamment élevée pour qu'un échange de gaz volumétrique substantiel survienne entre le flux de gaz d'échappement du moteur et le flux d'air d'admission.
