Abstract
Specific parameters of each of the injectors of the injection device of a combustion engine, especially a device with pre-injection with electronic control of a diesel engine, are determined. The curve of the instantaneous speed difference (DVi) of the engine shaft between the time of transition to the combustion top dead center point of the cylinder in question and a subsequent time preceding the transition to the combustion top dead center point of the following cylinder is established as a function of the value of the parameter to be determined, the other parameters of functioning being kept constant. The optimum value of the parameter is determined which corresponds to an extremum of the curve.
