Why does the pre injection of a Jeep Cherokee last so long?
The negative terminal of the injector is connected to ground in a pulsating way, because of the high current that will flow through the injector. After each pulse, a high negative inductive peak of approximately 40 V will appear, due to cutting the current through the injector. In this situation, the pre injection only lasts 296 µs (0.000296 s).
