Overview


Feedback from IQT™ users has revealed that flushing and purging the IQT™’s fuel system is one of the most complicated aspects of operating and IQT™. Flushing of the fuel system is required to remove any remnants of a previous test sample. Proper execution of the purging procedure is required in order to completely remove any air from the fuel injection system.

In order to simplify operation of the IQT™, AET has developed Automated Bleed Valve Controllers. Two pneumatically-driven rotary actuators are used to gently open and close the IQT™’s existing bleed valves, completely under the control of the IQT™ System Software (ISS). When installed, the controllers allow the IQT™’s operator to perform the flushing and purging procedures automatically at the touch of a button.
