Abstract (en)
[origin: FR2754852A1] The invention concerns a method for producing a synchronising signal for the electronic control system of an internal combustion engine, characterised in that it comprises the following steps: a) working out a synchronising signal in phase with a signal locating the passage of the pistons in a predetermined position, said synchronising signal being arbitrarily initialised; b) monitoring the operation of the engine when the predetermined conditions are fulfilled; c) modifying the control parameters of the engine for at least two given cylinders of which the operating cycles are out-of-phase by two working strokes; d) computing for the cylinders concerned an algebraic quantity representing the variations in combustion levels; e) deducing from this algebraic quantity the exactitude of the synchronising signal and correcting it if the arbitrary initialisation turns out to be erroneous.
