PRESENTATION
The 8412 module is designed for use with the ITB 234V test bench
enabling automatic analysis of diesel or gasoline jets via image
processing. It handles the injector driving by means of an Ipod power
module, as well as driving the camera, the fog extraction system
and the light sources (laser or strobe).
USE
The ICU system provides the TTL command signals for driving an injector and the equipment necessary for image acquisition. It must be accompanied by an additional power module adapted to the injector to be driven. For this, EFS offers the IPOD modules for solenoid and piezo-electric injectors.
Injector driving
The ICU system drives the injector with a temporal resolution of 0.1 µs. It can handle from 1 to 10 injections per revolution at frequencies of between 0.1 and 10 Hertz.
It can run in two modes :
- « Signal generator » mode
The driving is based on the injection parameters entered by the user from the supervision PC. The injector command can be inhibited while allowing other signals to be generated thus enabling the calibration of the vision system without injections.
- « One shot » mode
The ICU module receives external information (an impulse on a logical input) on the START input which synchronizes the execution of a single injection cycle (one motor revolution).
