•
LabVIEW FPGA and RT VIs with the following features for engine-synchronous,
multi-pulse injection control strategies:
–
Up to 16 pulses per injection cycle (Engine Speed Limited)
–
Configurable for any combination of angle and time triggering
–
Current control profile with the following characteristics:
•
Up to 8 phases
•
Each phase provides settings for upper and lower current dithering setpoints
•
Duration and drive voltage (battery or boost) specified for each phase
•
First phase can be configured to end after first peak
•
DI Calibrator application, which assists with firing injectors on a test bench for configuring
the injector current/voltage profile
•
Piezo injector operation for unipolar drive
•
Inverted piezo drive supported (Discharge = ON, Charge = OFF)
Each DI driver channel is individually controlled for timing and duration, but channel operation
cannot overlap. The NI 9751 cannot control piezo and solenoid actuator types simultaneously.
When configured for piezo mode, channel 3 is not available and you must short the terminals
together.
