The invention relates to a supercharged internal combustion engine (1) with a mechanical compressor (8) and a turbo-compressor (4, 5), which are coupled in series. The turbo-compressor is coupled downstream of the mechanical compressor. Between the connection (12) of the latter with the suction side of the turbo-compressor and the air intake (7) of the turbo-compressor, there is a non-return valve (13) arranged, which opens towards the turbo-compressor when the air requirement of the turbo-compressor exceeds the capacity of the mechanical compressor. |
