Abgasrückführungssystem für Brennkraftmaschine

摘要

In a multi-cylinder internal combustion engine (1), intake air aspirated to a collector (4) from an intake passage (6) of circular cross-section is provided to the cylinders via branch pipes (5A - 5D) connected to the collector (4). The exhaust gas recirculation system has an exhaust gas recirculation pipe (7) which branches off from an exhaust passage (3) and is connected to the intake passage (6). An exhaust gas inlet (8) leads recirculated exhaust gas from the exhaust recirculation pipe (7) substantially tangentially into the intake passage (6). In preferred embodiments, there are two exhaust gas inlets (8,9) 180 DEG apart.
