Method for determining an injection parameter in an internal combustion engine 50, the engine being provided with an injection line 14 for supplying a fuel quantity to an injector 12 and a leak line 16 for recovering fuel the injector, where the method comprises determining a flow rate in the injection line as a function of the fuel pressure difference measured in injection line, determining a flow rate in the leak line as a function of the fuel pressure difference measured in leak line and determining a flow rate of the injected fuel quantity in the injector as a difference between the flow rate in the injection line and the flow rate in the leak line. The method may also include determining a variation over time of a flow rate of fuel in the injection line and leak line as a function of the fuel pressure in the respective lines and integrating the variation over time. |
