  • User interface allows user to calibrate and customize injector current profile
  • Expansion options for a variety of applications including diesel common-rail fuel pressure control
The NI Direct Injector Driver System features an NI CompactRIO controller, Drivven Direct Injector Driver modules, and NI digital input modules. The system can synchronize injector channels with production crank/cam position sensors or research optical encoders. The system also accepts external digital fuel command signals from a production engine controller. The included Direct Injector Driver modules provide the power electronics you need to drive high-power solenoid or piezoelectric direct injectors.

NI offers this system in 3-, 6-, 9-, and 12-channel configurations (2, 4, 6, and 8 channels, respectively, when used with piezoelectric direct injectors). The system provides a digital input per channel for directly commanding each injector. The system controller is delivered with a preinstalled feature-rich application. The deployment version of the NI LabVIEW Software Calibration Manager (CalVIEW) is included for interfacing with and calibrating the system. The user interface is accessed by connecting a computer directly to the CompactRIO controller via an Ethernet cable or by putting the NI Direct Injector Driver System on a network. LabVIEW development tools are not required, but the free LabVIEW Run-Time Engine is required.

The NI 9215 C Series module option adds analog input channels for any application requiring +/-10 V feedback (pressure, temperature, etc). The Port Fuel Injector (PFI) driver option adds solenoid or valve actuation capabilities to the system. When both these options are used together, they add common-rail pressure control capabilities to the NI DI Driver System (software capabilities already built in).

The upgrade packages contain all of the additional hardware you need to expand your 3-channel NI Direct Injector Driver System to a 6-, 9-, and 12-channel system. The NI Direct Injector Driver System User Manual contains configuration information for how you should set up each system.

Fuel injectors and ECU are not included.
