Claims (4)
- REVENDICATIONS1. Procédé de pilotage d'un injecteur (1) disposé dans une ligne d'échappement (2) d'un véhicule automobile en vue de l'injection dosée d'un liquide, tel que notamment un agent réducteur, caractérisé en ce qu'il consiste à commander des ouvertures dudit injecteur pendant des laps de temps adaptés pour que le débit de liquide délivré lors de chacune des ouvertures consiste en une goutte de liquide.
- 2. Procédé de pilotage selon la revendication 1, caractérisé en ce que l'on commande des temps d'ouverture de l'injecteur (1) constants et en ce que l'on ajuste le dosage de liquide injecté en faisant varier la fréquence de ces ouvertures.
- 3. Procédé de pilotage selon l'une quelconque des revendications 1 ou 2, 10 caractérisé en ce que l'on commande des temps d'ouverture de l'injecteur (1) sensiblement de l'ordre de la milliseconde.
- 4. Procédé de pilotage selon l'une quelconque des revendications 1 à 3, caractérisé en ce que lors de l'arrêt d'un véhicule automobile, on poursuit la procédure d'injection goutte à goutte de liquide durant une période de temps prédéterminée suivant 15 cet arrêt.
