摘要：A method of controlling the fuel quantity injected into an internal combustionengine (1) having a number of injectors (4); for each injection, the method including thesteps of determining (14) a nominal energization time (EN); determining (15) a correctionenergization time ( ET); determining (16), in the event the required nominal fuel quantity(Qi) is below a predetermined threshold (SQ), a corrected energization time (EC) bycorrecting the nominal energization time (EN) as a function of the correction energizationtime ( ET); and exciting an injector for the corrected energization time (EC); the correctionenergization time ( ET) being determined by: performing, in the presence of apredetermined series of operating conditions of the engine (1), a succession ofenergizations of the injector (4) of gradually increasing energization times (ET);determining a quantity (Acc) related to the output torque of the engine (1); andcalculating the correction energization time ( ET) as a function of the quantity (Acc)related to the output torque.
