When it comes to injector duty cycle or pulse width though a diesel engine uses direct injection where the available time to inject fuel is much shorter than the full engine cycle time. WebThe ECU’s calculated injector pulse width must fit within this narrow window of fueling opportunity. If the ECU were to calculate a pulse width of 20 milliseconds, that would equal 100-percent duty cycle, which the injector can’t sustain because of injector head issues and the engine probably won’t tolerate.
