Abstract: An air intake unit for an engine of a vehicle includes a housing, a bypass air intake, a shutter element, and actuator. A plenum is defined inside the housing which can be connected to the engine. Air coming from the outside needed for the operation of the engine can be sucked into the plenum through the bypass air intake. The shutter element is coupled to the bypass air intake and is mounted to move between a closed position, in which the shutter element closes the bypass air intake, and an open position, in which the shutter element leaves the passage through the bypass air intake free. The actuator is configured to move the shutter element between the closed position and the open position. The actuator has a spring configured to generate, by expanding, an opening movement moving the shutter element from the closed position to the open position.

Abstract: A vehicle provided with an engine, at least one air intake through which the engine takes in the external air needed to operate, and an air filter arranged downstream of the air intake. The air filter presents: at least one filtering material panel having a corrugated shape having a plurality of crests disposed towards an outer environment and a plurality of valleys arranged towards an internal environment; an outer reinforcement mesh; an inner reinforcement mesh; and a heating device which is designed to heat the filtering material panel. The heating device presents: a plurality of electrical conductors, which are completely independent and separated from the outer reinforcement mesh, rest on the outer surface of the filtering material panel, and are arranged only and exclusively at the crests; and a supply device designed to cause an electric current to flow through the electric conductors so as to generate heat, due to the Joule effect.

Abstract: A method for manufacturing an electrified air filter for an intake system of an engine of a vehicle; the manufacturing method comprises the steps of: manufacturing an outer reinforcement mesh and an inner reinforcement mesh; manufacturing a filtering material panel; placing the reinforcement meshes on opposite surfaces of the filtering material panel so as to form a unit; bending the unit in a wave shape; and coupling the wave-shaped unit to a peripheral frame; externally coating the wires of said outer reinforcement mesh with an outer insulation; placing two strips of conductive metal material at the opposite ends of the outer reinforcement mesh; welding the two strips to the ends of the warp wires; and cutting each strip by means of through cuts so as to create spaces and hence obtain from the strip a succession of collectors that are separate from one another.

Abstract: An air intake unit for an engine of an aircraft; the intake unit has: a tubular housing; a first inlet opening which is obtained through an outer wall of the tubular housing and through which external air can be taken in; an air filter which engages the first inlet opening; a second inlet opening which is obtained through the outer wall of the tubular housing and through which external air can be taken in; a shutter device which is coupled to the second inlet opening and is movable between a closed position, in which it closes the second inlet opening, and an open position, in which it sets the passage through the second inlet opening free; and an actuator, which moves the shutter device.

Abstract: A control method for controlling an air intake system for an engine of a vehicle; the intake system has a main air intake coupled to an air filter provided with a heating device. The control method comprises the steps of: determining a pressure difference between upstream and downstream of the air filter; determining a variation speed of the pressure difference between upstream and downstream of the air filter by calculating the first derivative in time of the pressure difference between upstream and downstream of the air filter; and turning on and/or turning off the heating device based on the variation speed of the pressure difference between upstream and downstream of the air filter.

Abstract: A vehicle provided with an engine, at least one air intake through which the engine takes in the external air needed to operate, and an air filter, which is arranged in the area of the air intake; the air filter comprises: at least one wave-shaped filtering material panel; an outer reinforcement mesh, an inner reinforcement mesh; and a heating device which is electrically connected to a group of electrified wires of the outer reinforcement mesh and is designed to cause an electric current to flow through said electrified wires, so as to generate heat, due to the Joule effect, on the inside of said outer reinforcement mesh.
