PROCEDURE FOR DETERMINATION IN REAL TIME OF THE CHARACTERISTICS OF FUEL INJECTOR FLOW.

摘要

Procedure for determining in real time, and depending on the duration of the injection drive, of the flow characteristic of at least one electric drive fuel injector (2), which feeds an internal combustion engine (1), and mounted on a fuel supply circuit of said engine (1), said circuit comprising at least one pump (8), fed from a fuel tank (12) and connected to a common fuel feed ramp (3) of the injectors (2) of the engine (1), each injector (2) being driven by an engine control unit (5), comprising at least one calculator and at least one memory, such that in each cycle of the engine (1), each injector (2) delivers to said engine (1) a mass of fuel determined by said injector flow characteristic, which expresses the injected mass (Mi) according to an increasing function of the injection drive duration (t) of said iny ector (2), driven by said motor control unit (5).
