Air Fuel Ratio (AFR) Control

Gill Sensors & Controls provide all-in-one control systems, combining a full package of ignition and air/fuel ratio control systems, designed to increase efficiency and reduce emissions of industrial gas engines.

All components within the Engine Control System have been designed to work together, ensuring the complete engine control system is as efficient as possible. It is usually possible for engines that are unable to meet modern emissions regulations (RICE NESHAP) to be brought into compliance with the Gill Ultimate engine control system.

Gill Air / Fuel Controller

The Gill air/fuel controller has been designed to control air/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.
