Title (EN) METHOD FOR CONTROLLING INJECTION IN A DIESEL ENGINE
(FR) PROCÉDÉ DE GESTION DE L'INJECTION DANS UN MOTEUR DE TYPE DIESEL
Abstract:
(EN) The present invention relates to a method comprising the following steps: • determining a quantity of fuel to be injected, • injecting a main injection and a post-injection (Post1), • measuring the pressure (P cyl) and determining a torque produced (TQI) and a centre of combustion (AI50), • determining a variation in the overall quantity of fuel to be injected (DMF) according to the difference between a torque set point (TQI SP) and the measurement of torque produced (TQI). The variation in the overall quantity of fuel to be injected comprises a variation in the quantity of main fuel (DMF2) and a variation in the quantity of post-injection fuel (DMF3). The variation in the quantity of post-injection fuel to be injected is dependent on the difference (DTQI) between the torque setpoint (TQI SP) and the measurement of torque produced (TQI) and on the difference (DAI50) regarding the centre of combustion.
(FR) La présente invention a pour objet un procédé comportant les étapes suivantes: · détermination d'une quantité de carburant à injecter, · injection d'une injection principale et d'une post-injection (Post1), · mesure de la pression (P cyl) et détermination d'un couple produit (TQI) et d'un centre de combustion (AI50), · détermination d'une variation de quantité globale de carburant à injecter (DMF) en fonction de la différence entre une consigne de couple (TQI SP) et la mesure de couple produit (TQI). La variation de quantité globale de carburant à injecter comprend une variation de quantité de carburant (DMF2) principale et une variation de quantité de carburant (DMF3) de post-injection. La variation de quantité de carburant à injecter de post-injection est fonction de la différence (DTQI) entre la consigne de couple (TQI SP) et la mesure de couple produit (TQI) et de la différence (DAI50) concernant le centre de combustion.
