The Direct Injector Driver System (DIDS) features a CompactRIO controller, 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. It 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 Software Calibration Management Toolkit for LabVIEW (SCM) is included for interfacing with and calibrating the system. You can access the user interface by connecting a computer directly to the CompactRIO controller via an Ethernet cable or by putting the Direct Injector Driver System on a network. LabVIEW development tools are not required, but the free LabVIEW Run-Time Engine is required.
The NI 9201 C Series module option adds analog input channels for any application requiring ±10 V feedback (pressure, temperature, and so on). The Port Fuel Injector Driver option adds solenoid or valve actuation capabilities to the system. When these options are used together, they add common-rail pressure control capabilities to the Direct Injector Driver System (software capabilities already built in).
Fuel injectors and ECU are not included.
