English to French Tech/Engineering Patents (in a patent) SYSTEM AND METHOD FOR VARIABLE ACTUATION OF A VALVE OF AN INTERNAL COMBUSTION ENGINE, WITH AN ELECTRICALLY OPERATED CONTROL VALVE HAVING AN IMPROVED CONTROL

said valve modes including a late-valve-opening (LVO) mode, in which opening of the engine valve is delayed with respect to the start of the lift cycle determined by the cam profile (14),

said System being characterized in that said electronic control unit (25) is programmed in such a way that when said late-valve-opening mode is actuated, the control valve (24) opens the aforesaid communication in advance with respect to the end of the lift cycle of the cam, and not after closing of the engine valve (7), in such a way as to prevent or reduce a decrease in pressure in the volume of pressurized fluid (C) after closing of the engine valve (7).

characterized in that in said late-valve-opening (LVO) mode, said electronic control unit (25) is programmed in such a way that the control valve (24) opens the aforesaid communication substantially when the engine valve (7) closes.
