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.

Abstract: A lock coupling between two mechanical components and presenting: at least one pair of coupling elements, each of which presents an “L”-shape and protrudes from a first mechanical component; and at least one pair of tracks, each of which is made through a second mechanical component, presents the shape of an arc of circumference, ends with a flared inlet opening, and is engaged in use by a coupling element; each track presents a dimension so as to prevent the axial removal of the coupling element along its entire length except for an inlet opening at which the coupling element can be axially removed.

Abstract: A tumble system for the intake manifold of an internal-combustion engine is provided with a number of cylinders. The tumble system is provided with at least one throttle valve for varying the section of passage of air through an intake pipe, which connects a cylinder with the intake manifold. The throttle valve has a throttle butterfly mounted so as to rotate under the thrust of an actuator device equipped with at least one actuator element, which is made of a shape-memory material that generates a torque by modifying its own geometry following upon application of an external stress of a physical nature.
