Brief description of the correction of a magnitude bound to the rotation of an internal combustion engine as a function of the dissymmetries of a target bound in rotation to the engine

摘要

The method consists in defining a value of the quantity (cg) for each of the angular sectors of the target (2) corresponding to a combustion phase - expansion of each cylinder of the engine, and on at least one engine cycle in the phase of an interruption of the ignition and / or fuel supply, at least one engine speed greater than the idling speed, to calculate the mean values obtained, for all the sectors, to define for each sector, a term of compensation equal to the product of the difference between the mean values and the value of the quantity (cg) for this sector, by a coefficient which may be equal to 1 or a function of the load and / or the speed of the engine, and to add to each sector, the term "compensation corresponding to the values of the quantity (cg) defined in the ignition phase and for feeding fuel to the sector at least over a range of speed of the motor containing the operating conditions for which the cut-off of the ignition and / or power supply has been applied. & br / application to the internal combustion engines of the type for injection for motor vehicles.
