摘要： In an internal-combustion engine equipped with an electronically controlled hydraulic system for variable actuation of the intake valves (7), an operating step of refilling prior to ignition of the engine is activated in order to refill a pressure chamber (C) of the system with fluid when, after a prolonged inactivity of the engine, the aforesaid chamber has been emptied. In this refilling operating step, the supply of fuel to the engine is inhibited, and the camshaft (11) of the engine is driven in rotation following upon activation of the engine-starting electrical machine (53). In this way, a pumping member (16) associated to the tappet (15) for actuating an intake valve (7) is used as pump for drawing fluid into the pressure chamber (C) from an auxiliary fluid tank (600). During this step, an electrically actuated control valve (24) is opened and closed in synchronism with the movement of the pumping member (16) so as to be open when the pumping member (16) advances towards the pressure chamber (C) and be instead closed when the pumping member (16) moves away from the pressure chamber (C).

摘要： A supercharged diesel engine is equipped with an electronically controlled hydraulic system for variable actuation of the intake valves of the engine. The cam that controls each intake valve (1) has an additional lobe (41) for causing an additional opening of the intake valve, during the exhaust stroke, so as to provide an exhaust-gas recirculation directly inside the engine. Said additional lobe is shaped in such a way as to give rise to a profile (B) of the additional lift of the valve as the crank angle varies with a boot conformation, including an initial stretch (B i ) with a gentler slope extending from a point (X) of zero lift corresponding to the expansion stroke in the engine cylinder. The engine is moreover equipped with a duct for exhaust-gas recirculation of the long-route type.

摘要： A solenoid valve, particularly of the type to be used for controlling a hydraulic system for variable actuation of the valves of an internal-combustion engine, has a valve element (105) co-operating with a valve seat (104) and a pusher element (113), separate from the valve element (105), which is pushed against the valve element (105) by the movable core (112) of the solenoid valve when the solenoid (111) of the solenoid valve is energized in order to bring the valve element into contact with the valve seat. After de-energization of the solenoid (111), the time necessary for bringing back the pusher element (113) into the resting condition in contact with the valve element (105) is reduced thanks to the application of a braking current (CF) to the solenoid (111) of the solenoid valve during the stage in which the movable core (112) and the pusher element (113) associated thereto displace in the direction opposite to the direction of the movement generated by the magnetic field of the solenoid, following upon de-energization of the solenoid valve.

摘要： An internal combustion engine is equipped with a variable actuation system for the intake valves (7) including a chamber of fluid under pressure (C) interposed between the intake valve (7) and the respective controlling cam, and a solenoid valve (24) whose opening causes the pressure chamber (C) to discharge such as to determine the rapid closure of the valve (7) by effect of the respective biasing spring means (9), even when the respective cam would tend to keep the valve open. The variable valve operation system is used in combination with the use of cams controlling the intake valves shaped in such a manner as to give rise to an intake valve lift profile including a boot portion (C2) at substantially constant lift. Such boot portion is provided in the initial part of the intake valve opening cycle, in advance with regard to the TDC, in the case of a supercharged direct-injection petrol engine. In the case of a diesel engine, on the contrary, the boot portion (C2) is provided in the final part of the intake valve opening cycle, after the BDC.
