Abstract (en)
The device enables an injector (L) with a low resistance to be driven with a "peak & hold" function, reducing dissipation both in the control circuit and in the injector itself. For this purpose, the load constituted by the injector (L) is supplied by means of two power units (TR1, TR2) which are activated selectively by three timers (T1, T2, T3).
