Method of injection of fuel in an internal combustion engine, taking into account the evolution of the injectors in the course of time.

摘要

- Method for injecting a mass m via a fuel injector of a common rail with an internal combustion engine. - it defines a physical model f, which provides an estimate of mass of fuel injected as a function of a time of injection and a pressure in the common rail. Then, after having measured the pressure in the common rail, this model is used to calculate the time t of the injection of fuel necessary for the injection of the mass m of fuel. Finally, fuel is injected via the injector during the time t. thereafter, when the aging of the motor is such that the difference between the injected mass desired and the mass actually injected is important, the physical model recalibrates. - application to the engine control.
