PROCEDE ET DISPOSITIF DE REGLAGE DE L'INSTANT D'OUVERTURE D'UN INJECTEUR DE CARBURANT, POUR MOTEUR A COMBUSTION INTERNE A INJECTION DIRECTE

摘要

The invention concerns a method which consists in: a) emitting a series of sparks into a cylinder (1) of the engine, filled with an air/fuel mixture to be ignited, at predetermined successive times; b) identifying the one spark which initiates ignition of said mixture; c) evaluating the difference separating emission time of said spark from a predetermined ignition time ensuring supply by the engine of a predetermined mechanical power; and d) correcting the opening time of said fuel injector (3) on the basis of said difference, so as to initiate subsequent ignitions of the air/fuel mixture in said cylinder (1) at said predetermined time.
