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 co-operating with a valve seat and a pusher element, separate from the valve element, which is pushed against the valve element by the movable core of the solenoid valve when the solenoid 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, the time necessary for bringing back the pusher element into the resting condition in contact with the valve element is reduced thanks to the application of a braking current to the solenoid of the solenoid valve during the stage in which the movable core and the pusher element 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 for motor vehicles, for example a petrol-fuelled engine or a gas-fuelled engine, is provided with an electronically controlled hydraulic system for variable actuation of the intake valves. The system of variable actuation of the intake valves is governed by an electronic control unit that is programmed for performing at least once, at the start of the life of the engine, an activity of supervision of the functions of self-adaptive control of the air-fuel ratio. The supervision activity is based upon identification of a constant ratio between a delta in the value of the crank angle used by the electronic control unit and the error in the estimation of the air-fuel ratio by the electronic control unit when the system of actuation of the intake valves operates in late-opening mode. The activity of supervision envisages that the electronic control unit detects and stores the variation in the value of the crank angle (crank-angle delta) that must be applied to the value of the crank angle used by the electronic control unit in order to reach an estimated value of the mass of air taken in that basically coincides with the real value.

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 has an additional lobe for causing an additional opening of the intake valve, during the expansion and exhaust strokes, so as to provide an exhaust-gas recirculation directly inside the engine. The aforesaid additional lobe has its descending stretch radiused to the main lobe with a stretch corresponding to a non-zero lift of the valve in such a way that the profile of the lift of the valve has a portion corresponding to a substantially non-zero value of the lift that radiuses the descending stretch of the profile of the additional lift to the ascending stretch of the profile of the main lift.

摘要： Systems and methods of actuating engine valves using a hydraulic valve actuation system are disclosed. The valve actuation system includes a master piston and two slave pistons slidably disposed in bores provided in a housing. The master piston and two slave pistons are connected together by a hydraulic circuit. Linear motion imparted to the master piston is transferred to the two slave pistons via the hydraulic circuit. In turn, the two slave pistons may actuate one or more engine valves directly or through an intermediate valve bridge. A valve seating device may be provided to assist in seating the engine valves in embodiments where the valve actuation system is adapted to provide variable valve actuation.
