摘要：
A hysteresis-type electronic controlling device is provided for fuel injectors that includes, but is not limited to a power driving unit for driving the fuel injectors with an electric signal, a control stage connected to the power driving unit and a sensing stage fed by the power driving unit and feeding the control stage, the device has a feedback frequency control stage for measuring a waveform period of the signal feeding the fuel injectors; the feedback frequency control stage is fed by the control stage with an electric signal. A fuel injector control method is also provided that includes, but is not limited to driving fuel injectors with an electric signal coming from a power driving unit fed by a control stage , sensing the signal with a sensing stage, and measuring a waveform period of the signal through the feedback frequency control stage.
