Abstract

Automatic ignition advance obtaining device for internal combustion engines, mainly for motor vehicles, characterized in that it comprises an angular encoder that provides pulses translated into a coded value A, depending on the angular variation α between a reference position taken on the engine flywheel and a variable position of said flywheel, whose value A is applied to a first comparator input, by means or not of a code converter and a tachometric generator that provides a coded value B, which has a predetermined value that is a function of the rotation speed of the internal combustion engine, this value B being applied to a second input of the comparator, in order to obtain, at the moment when A coincides with B, an ignition pulse that generates the ignition spark at this moment, which produces a relationship through the coded values A and B, and according to a linear law or not according to the required advance law, between the angular variation α and the number of turns of the motor that corresponds to the relationship given by the desired advance curve.
