Abstract

La presente invención se refiere a un método para controlar eléctricamente un accionador de válvula en un motor de 2-tiempos o 4-tiempos, donde el accionador comprende un primer solenoide (A) con un émbolo (5) y un segundo solenoide (B) con un émbolo (15), en donde el motor tiene al menos un cilindro (1) con al menos una válvula de motor libremente controlable que comprende un disco de la válvula (10) con vástago de la válvula asociado (11) y un resorte de válvula (4) y donde se introduce aire, o los gases de escape son evacuados de, una cámara de combustión (3) pasando una parte inferior del vástago de la válvula con el disco de la válvula mediante al menos un canal (2) en el cilindro, en donde el accionador de válvula es activable para abrir la válvula del motor. La invención se caracteriza en que tanto el primero como el segundo solenoide son activados durante la apertura de la válvula del motor.
