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.
