Abstract
A supercharged internal combustion engine with an exhaust driven turbo compressor (4,5) and a mechanically driven compressor (11), the pressure side of which is connected to the suction side of the turbo compressor. A conduit (18) for recirculation of exhaust opens into an ejector device (23,24) in a bypass conduit (17a, 17b), which branches downstream of the turbo compressor from an intake conduit (15) provided with a damper (16).
