AFR200 SERIES - Fuel and Ignition Management System (FIMS)

The Air Fuel Ratio (AFR) 200 series controller is part of the GAC comprehensive fuel management system for gaseous-fueled, spark-ignited engines ranging from 1L to 13L+. The AFR200 series controllers when used in conjunction with the ICM200 (Ignition Control Module) offers a complete Fuel and Ignition Management System (FIMS) referred to as the FIMS500 system. Each of these controllers has the ability to work independently of the other in the event of a failure.

ICM200 Series - Fuel and Ignition Management System (FIMS)

  • Capable of up to 8 cylinders sequential or 16 cylinders wasted-spark
  • High-energy inductive ignition system
  • Supports camshaft / crankshaft engine position sensors of either the Hall Effect or variable reluctance type
  • Fixed timing with in-field global trim capability as well as two variable timing maps based on engine speed and load

The Ignition Control Module (ICM) 200-series is an intelligent electronic control module which is part of GAC’s distributor-less ignition system. The ICM triggers an inductive coil by charging the coil with the appropriate amount of energy for high voltage induction into the engines’ spark plugs.
