Control a peak and hold injector.
None (Main library). (See Section 2.3, “Licensed Features”.)
The peak and hold injector output block causes a stepped current signal to be generated at the selected injector frequency, in which the current is firstly controlled to the peak current threshold for the duration determined by the peak duty cycle, after which it is controlled to the hold current threshold for the remaining duration of the peak-hold duty cycle (i.e. the duration of the peak-hold duty cycle minus the peak duty cycle), after which the current falls to zero until the beginning of the next cycle.
The injector frequency, clock frequency, peak duty cycle and peak-hold duty cycle are all driven from block inputs. The actual duty cycles are scaled by the mask parameter Min/Max duty cycle as follows:
output peak duty cycle = Minimum duty cycle + (Maximum duty cycle - Minimum duty cycle) * peak_duty_cycle
output peak-hold duty cycle = Minimum duty cycle + (Maximum duty cycle - Minimum duty cycle) * peak_hold_duty_cycle
Furthermore, the output peak-hold duty cycle is always constrained to be at least as great as the output peak duty cycle.
The channel output can be offset from other injector channels of the same frequency. The Offset parameter is used to delay the start of the injector cycle, so that the injector will not activate at the same time as other injector signals of the same frequency.
If the inport fault input is non-zero, then the output peak duty cycle is set to the mask parameter Peak default duty cycle and the output peak-hold duty cycle is set to the mask parameter Peak-hold default duty cycle.
