Abstract: A piston pump for feeding a liquid in a vehicle having at least one piston, which is configured to cyclically slide inside a housing between a top dead centre and a bottom dead centre. The liquid is usually fed along a main feeding direction from a suction duct to a delivery duct. The piston pump has two solenoid valves, which are each arranged in the suction duct and in the delivery duct, respectively, and are designed to be operated by an electronic control unit so as to reverse the liquid feeding direction from the main feeding direction to a secondary feeding direction opposite the main liquid feeding direction and/or so as to adjust the cylinder capacity of the piston pump. The piston is operated by an electromechanical actuator, in particular comprising an electromagnet.

Abstract: An exhaust system provided with exhaust gas after-treatment for a combustion engine comprising an exhaust pipe and a pumping device, which is buried inside the tank, from which it draws so as to feed a water solution of urea under pressure to an electromagnetic injector; the tank is supplied with urea powder and water, which are mixed on the inside so as to obtain a water solution of urea with a variable concentration; and a water supply circuit to supply water to the tank, which is provided with a first pipe, which draws the water from a basin and is regulated by a first valve, which allows water to be introduced into the tank, if necessary, or to be drained to the surrounding environment when the water quantity already contained in the tank is sufficient.

Abstract: A device to supply an internal combustion engine with water comprising one single tank of an exhaust system provided with exhaust gas after-treatment; the tank is divided, on the inside, into a first powder urea storage area and a second water collecting area, and wherein the powder urea and the water are mixed inside the tank so as to obtain a water solution of urea with a variable concentration, the device comprises at least one second electromagnetic injector, which is designed to inject water into the internal combustion engine, and a second pumping device, which is drowned inside the tank and draws from the second water collecting area in order to supply water under pressure to said at least one second electromagnetic injector.

Abstract: A method is described to control an actuation profile of an electromechanical linear actuator device of an internal combustion engine designed to control the movement of a component; the internal combustion engine comprises a sensor, which faces the actuator device and is designed to detect the noise generated by the movement of the component; the method comprises the steps of acquiring, by means of the sensor, the intensity of a signal generated by the impact of the component against a limit stop; identifying a first listening window of the signal associated with said impact; calculating a noise index inside the listening window; comparing the noise index with a reference value; and controlling the actuation profile of the actuator device based on this comparison.

Abstract: A device for the production of water on board a vehicle comprising a duct, where an air flow flows; a tank, which contains a quantity of adsorbing material and is arranged along the duct; a first and a second adjustment valve for the adjustment of the duct, which are arranged upstream and downstream, respectively, of the tank and are movable between an opening position, in which the air flow can flow towards the tank, and a closing position, in which the air flow cannot flow towards the tank, and vice versa; wherein the first and the second adjustment valve are controlled in a synchronous and concordant manner; and a heating element, which is designed to heat the adsorbing material when the first and the second adjustment valve are in the closing position.
