Abstract
A method and device for adjusting at least one parameter conditioning at least partially the operation of an internal combustion engine with controlled ignition, this technique using the detection of the passage of the flame front in the combustion chamber. From the distribution or histogram based on several of these angular divergences corresponding to a predetermined number of cycles n, a magnitude is elaborated or determined for controlling the operation of the engine and the parameter conditioning the operation of the engine is modified so that the control magnitude takes on a predetermined value.
