Abstract
A detection process and device for electronic injection control of a multicylinder engine of an automobile engine, which performs the functions of measuring the speed of rotation of the engine, pinpointing the angular position of the top dead center of each cylinder of the engine, and identifying at any time which one of the cylinders for which the injection of fuel is to take place. The device includes a multipolar ring provided with multiple north and south magnetic poles distributed alternately on the circumference of the ring; a pair of sensors sensitive to the magnetic field produced by the multipolar ring mounted facing the ring and spaced angularly from one another; and an electronic processing interface connected to the sensors to deliver signals to a computer for control of the electronic injection of the engine.
