A method for real time determination of the gain of a fuel injector (2) of an engine (1), fed by a circuit having a fixed volume devoid of a permanent return upstream from a pump (8) connected to a common feed ramp (3) for the injectors (2) controlled like the pump (8) by at least one computer (5), wherein the local gain of at least one injector (2) is determined according to the variation of the mass of fuel injected into the engine (1) by the set of injectors (2) and resulting from the application on said injector (2) which is considered from a command for a duration of injection which is different from that applied on the injector or other injectors (2). The invention can be used to determine the flow characteristics of injectors of internal combustion engines. |
