The AF120 Air/Fuel ratio control system provides cost effective emissions control for gaseous fueled engines used in demanding applications such as Cogeneration, Water Pumping, Gas Compression and Power Generation, with a proven track record of reducing emissions, and more importantly holding emissions over a long term without constant manual engine tuning.The AF120 System 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 cat. The system consists of the AF120 control module, a wide...
