INTERNAL COMBUSTION ENGINE COMPRISING AN INTAKE SYSTEM

摘要

The invention relates to an internal combustion engine (1) comprising an intake system (2), which comprises a first compressor (5) preferably driven by an exhaust gas turbine (4), and an exhaust system (3). Said engine also comprises an exhaust gas recirculation system (13) with at least one exhaust gas recirculation line (13a) for recirculating exhaust gas from the exhaust system (3) to the intake system (2). The exhaust gas is recirculated by means of a compressed air system (14) using a Venturi device (12), and the compressed air system has a second compressor (10) which is preferably mechanically driven. In order to improve the exhaust gas quality when the engine is in the transient mode, the suction side (10a) of the second compressor (10) is connected to the intake system.
