Abstract (en)
[origin: EP1519012A2] The device has a processor (501) for controlling a defluxing current circulating in a coil (507) of an electromagnet (506) of an electromechanical actuator (502), where the current generates a magnetic field opposite to the field of a magnet. The processor controls the defluxing current according to duration of opening of a valve (510) determined from engine parameters. The engine parameters are speed of motor, quantity of air input in concerned cylinder, an input gas pressure, rate of recycling of exhaust gas by the input gas and number of active input valves by cylinder. An independent claim is also included for an internal combustion engine.
