AF120 Air/Fuel Ratio Controller

The AF120 Air/Fuel Ratio Controller provides cost-effective emissions control for gas fueled engines used in static 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 Converter.

  • Outputs to stepper or current controlled bypass valves
  • Fast start-up from heated UEGO sensor
  • Programmable valve start position and offset
  • Programmable load map
  • Free, easy to use windows based GUI
  • Drives pneumatic controls valves with 4-20mA output
  • Proportional, integrated control loop controls Lamda value to set point.

The Gill AF120 controller has been designed to control air or fuel ratio of both rich (stoichiometric) or lean burn industrial gas engines. The system improves engine efficiency and eliminates the requirement for constant manual engine adjustment often associated with other air/fuel ratio control technologies.

Gill Engine Controls combines the MaxiSpark Ignition System with the Zerodrift Air/Fuel Ratio Control System, designed to increase efficiency and reduce emissions of industrial gas engines. All components within Engine Controls have been designed to work in harmony, ensuring the complete engine control system is as efficient as possible.
