"textContent": "A method for determining a quantity of fuel injected into a cylinder of an internal combustion engine including an injection rail includes:—measuring the pressure prevailing in the injection rail during fuel injection from the rail into a cylinder;—filtering the pressure measurement;—determining the relative minimum and maximum points of the filtered pressure curve;—insofar as a first (Pdrop1) pressure drop followed by a pressure rise and then a second (Pdrop2) pressure drop is identified, determining a physical quantity that makes it possible to characterize the first pressure drop and the second pressure drop; and—determining the quantity of fuel injected by applying the bulk modulus for the two pressure drops identified as a function of the temperature in the injection rail.",
