Air Fuel Ratio Controller AF1200 pages
AFl 20 Ah/Fuel RaHo Control
The AF120 control module can be used within a variety of control systems. In the carburettor bypass
configuration the Gill AFl 20 fuel valve can be utilised. Alternatively the module can be used to control
fuel pressure regulator systems and systems requiring turbo waste gate control. The AFl 20 fuel valve
has been specifically designed to operate with the AFl20 control module for medium sized engines
where a fuel bypass system can be utilised. Using
a stepper motor with over two hundred steps
provides absolute precision around the set
point.
