More Information
Summary:Hysteresis-type electronic controlling device (1) for fuel injectors comprising a power driving unit (20) for driving the fuel injectors with an electric signal (Si), a control stage (10) connected to the power driving unit (20) and a sensing stage (40) fed by the power driving unit (20) and feeding the control stage (10); the device (1) has a feedback frequency control stage (30) for measuring a waveform period of the signal feeding the fuel injectors; the feedback frequency control stage (30) is fed by said control stage (10) with an electric signal (si). A fuel injector control method, comprising the steps of driving fuel injectors with an electric signal (si) coming from a power driving unit (20) fed by a control stage (10) and the step of sensing the signal (si) with a sensing stage (40); the method comprises a step of measuring a waveform period of the signal (si) through the feedback frequency control stage (30).
