Abstract (en)
[origin: WO2014091273A1] This method for controlling an injection system in an internal combustion engine having a common rail includes: - a first step 2000) before a given injection phase of a given cylinder, in which the requested fuel quantities (QB, QM and QA) and the requested injection start times (tB, tM and tA) are computed for each individual injection of the given injection phase, - a second step 3000) in which an adaptive model (K, W) of the variations of the pressure in the common rail is used to compute calculated values (PBi, PMi, PAi. ΡBf, PMf, PAf) of the pressure in the common rail for each individual injection of the given injection phase, in accordance with the requested fuel quantities (QB, QM, QA) and the requested injection times (tB, tM, tA) set during step 2000), - 4000) the values (P'Bi, P'Mi, P'Ai, P'Bf, P'Mf, Ρ'Af) of the pressure (P) in the common rail are recorded during each individual injection of the given injection phase, - 5000) the adaptive model (K, W) is adjusted depending on the difference between the computed pressure values (PBi, ΡΜi, PAi, PBf, PMf, PAf) of step 3000) and the recorded pressure values (P'Bi, P'Mi, P'Ai, P'Bf, P'Mf, P'Af) of step 5000).
