Abstract
Improvements in electronic advance systems for internal combustión engines, particularly for motor vehicles, capable of providing a command signal for the activation of an electronic ignition circuit, with a constant advance angle of a pre-set maximum value correspondingly and above of a preset number of revolutions of the engine, and with a variable advance angle, with pre-established law, for a number of revolutions of the engine lower than said pre-established number, characterized in that said systems consist, for each ignition phase, in: a ) detect position information of a rotary member with the motor, in correspondence with the pre-established maximum advance angle and in correspondence with the pre-established minimum advance angle; b) use the detected information in correspondence with the maximum advance angle to determine, at a preset constant level, the beginning of a variable signal as a function of the angle of advance and use the information detected in correspondence with the minimum advance angle to determine both the end of said signal and the start or adaptation, if it has already started, of another variable signal depending on the number of engine revolutions; c) using said variable signal as a function of the number of revolutions of the engine to impose on the variable signal as a function of the angle of advance a development, whatever the number of revolutions of the engine, at the constant angle defined by the angular distance between the maximum and minimum advance angles; and d) finally confronting the two said variable angles to obtain a command signal for the activation of the ignition circuit.
