ABSTRACT:
A pulse generator is disclosed, intended to supply information as to the speed of rotation and the phasing of an internal combustion engine of the injection type, said generator comprising at least a magnetosensitive switching device formed by a magnetoresistive element positioned at a preselected location along a circumference, means for producing a magnetic field for switching said magnetosensitive switching device mechanically connected to the main shaft so as to be rotated at a speed proportional to the speed of rotation of the engine and with a preselected phase relationship with respect thereto, said magnetic field periodically influencing said switching device for a length of time and at a frequency which are a function of the engine speed of rotation and with a phase which is a function of the phase relationship aforementioned.
