AF120 AIR/FUEL RATIO CONTROLLER Engine Controls

 

Introduction

The AF120 Air/Fuel Ratio Controller provides cost-effective emissions control for gaseous fueled engines used in demanding industrial applications. The module is designed to accurately control the air/fuel ratio of stoichiometric engines fitted with a three way catalytic converter, and lean burn engines with or without a Catalytic Convertor.

The AF120 Air/Fuel Ratio Controller can be used within a variety of control systems. In the carburettor bypass configuration the Gill AF120 fuel valve can be utilised. Alternatively the module can be used to control fuel pressure regulator systems and systems requiring turbo waste gate control.
