ABSTRACT:
An intake manifold with integrated canister circuit for a supercharged internal combustion engine. The intake manifold includes a tubular body in which a plenum is defined. A sorting chamber is in a wall of the tubular body. A canister solenoid valve is arranged in the sorting chamber and is adapted to adjust the introduction of gasoline vapors into the sorting chamber itself. A first pipe in the wall of the tubular body puts the sorting chamber into communication with the plenum, and defines a first branch of a recovery pipe. A one-way valve is arranged in the sorting chamber at the first pipe. A second pipe in the wall of the tubular body puts the sorting chamber into communication with the intake pipe upstream of a compressor, and defines an initial portion of a second branch of the recovery pipe.
