Abstract: A spark-ignition supercharged internal-combustion gasoline engine is equipped with a system for variable actuation of the intake valves including a pressurized fluid chamber set between intake valve and a respective control cam, and an electrically actuated valve, the opening of which vents the pressure chamber so as to cause rapid closing of the valve, as a result of the respective elastic return means, even when the respective cam would tend to keep the valve open. The variable-valve-actuation system is used in combination with control cams of the intake valves shaped in such a way as to generate an intake valve lift profile including a boot portion with substantially constant lift. The boot portion is provided in the final part of the opening cycle of the intake valve, after bottom dead center.

Abstract: A device for selection and engagement of the gears of a gearbox for motor vehicles has a control shaft mounted rotatable and axially movable with respect to the casing. Mounted on the shaft is a hub having an engagement finger for controlling gear engagement devices, which is configured to oscillate in the space between two fingers of a selection mask, which is mounted on the shaft axially movable therewith and is guided with respect to the casing so as not to follow rotation of the shaft and the hub when a gear is engaged. During displacement of the engagement finger towards an extreme position preliminary to the engagement of the reverse gear, the selection mask is forced to move temporarily into a rotated position, wherein it actuates one or more of the selector devices of the forward gears to enable silent engagement of the reverse gear.

Abstract: There is described a control method for controlling the fuel injection pressure of a common rail injection system of an internal combustion engine, the injection system having a high-pressure pump for supplying high-pressure fuel to the common rail, and for performing, at each engine cycle, a first and at least a second fuel delivery synchronously with respective fuel injections to the engine; a regulating device for regulating the fuel pressure in the common rail; and an electronic control unit supplying the regulating device with a control signal to regulate the fuel pressure in the common rail. The control method provides for determining a first value of the duty cycle of the control signal as a function of a required pressure value in the common rail, in turn a function of the power required of the engine, and as a function of an actual pressure value in the common rail; determining a second value of the duty cycle of the control signal as a function of the first value of the duty cycle, and as a function of a total correction coefficient; causing the duty cycle of the control signal to assume the first value during the first fuel delivery; and causing the duty cycle of the control signal to assume the second value during the second fuel delivery.
