<p>Method and apparatus for periodically controlling the timing of an internal combustion engine in which two voltages are generated, one of which corresponds to a selected portion of one complete rotation of the engine shaft whereas the other is a function of time. A control signal is generated when the second voltage becomes equal to the first. The first voltage is of the form aq+b+ce - gamma q, in which a, b, and c may be any constants and gamma is a positive constant, while the second voltage is of the form d+ ge - alpha t, in which d and g may be any constants and alpha is a positive constant.</p> |
