COMMAND AND SYNCHRONIZATION MODULE: ICU

ICU – command and synchronization module

The ICU module is a command and synchronization module. It provides control signals to drive an injector as well as the equipment necessary for image acquisition for the INJETVISION spray visualization system.

It has several operating modes:

• In internal mode, it generates its signals according to user-defined parameters without synchronization with an external signal.
• In synchronized mode, it receives external information (a pulse on a logic input) which it synchronizes to generate the ‘injector control’ command.

  In internal mode, it generates its signals according to user-defined parameters without synchronization with an external signal.

Control module for operating the injector.

• Injector control with a time resolution of 0.1 µs.
• Controls 1 to 10 injections per revolution at frequencies between 0.1 and 10 Hertz.
• Operates either in signal generator mode (injection parameters entered by the user) or in single-shot mode (receives a pulse on a logic input).

An additional power module adapted to the injector to be controlled is required: IPoD coil (solenoid-type injector) or IPoD piezo (piezoelectrique injector).

Control module for operating equipment INJETVISION

• The camera for taking instant images: it defines the instant of the image taking in relation to the 1/T signal and the exposure time with a resolution of 0.1 µs.
• The fog extraction device, which is responsible for the automatic cleaning of the chamber required during successive injections.
• 4 additional signals to drive 2 pulsed laser sources. These signals can also be used to control strobe lighting.
