Process for determining the operating parameters of an injection device

摘要

A process for determining the operating parameters of an injection device of a combustion engine includes the steps of: (a) selecting an injector to test; (b) calculating a mean velocity associated with a preceding injector arranged before the injector to test; c) applying to the injector to test an injection control signal including at least one test pulse having an adjustable parameter; (d) calculating a mean velocity associated with the injector to test; (e) calculating a difference between the mean velocity calculated in step d) and the mean velocity calculated in step b); (f) repeating steps b) to d) for at least another engine cycle, each time varying the parameter of the test pulse; (g) determining a value of the parameter of the test pulse for which the mean velocity difference exceeds a predetermined threshold; and storing the parameter value.
