ARCHITECTURE D'ECHAPPEMENT D'UN MOTEUR A COMBUSTION INTERNE, MOTEUR A COMBUSTION INTERNE COMPORTANT UNE TELLE ARCHITECTURE D'ECHAPPEMENT ET PROCEDES UTILISANT CE MOTEUR ET CETTE ARCHITECTURE D'ECHAPPEMENT

摘要

The architecture (100) has an exhaust conduit (16) traversing an exhaust gas treatment device (12) and successively with inlets of recirculation and by-pass conduits (41, 42) and an exhaust flap (44). The inlet of the conduit (41) traverses a cooling device (40) i.e. exhaust heat recovery system, and opens into an intake conduit (4) upstream of a compressor (2) of a turbocharger (14). The inlet of the conduit (42) opens into the conduit (41), and is placed downstream of the device (40). The flap is adapted to different positions to vary a passage section of the conduit (16). Independent claims are also included for the following: (1) an internal combustion engine comprising an intake conduit (2) a method for reducing pollutant emissions at the starting of an internal combustion engine (3) a method for heating a fluid of an internal combustion engine using an exhaust architecture (4) a method for recirculating an exhaust gas using an exhaust architecture (5) a method for utilizing an internal combustion engine.
