Abstract (en)

[origin: FR2766872A1] The invention concerns a method for correcting a fuel injection internal combustion engine (1) torque jerks comprising an electronic engine control system (7) determining according to the engine operating conditions, the engine control parameter values ( alpha PAP,Av,Ti), whereby at least one control parameter ( alpha PAP) is corrected in response to the engine torque oscillations. The invention is characterised in that it comprises the following steps: computing said control parameter value ( alpha PAP) on the basis of the accelerator pedal ( alpha PED) position; determining the correction (Corr alpha PAP) to be applied to said control parameter ( alpha PAP) by filtering the engine shaft rotation speed (N).
