Compliance AFR-9R



compliance controls AFR-9R air fuel ratio controller

Rich-Burn Air/Fuel Ratio Control System

The AFR-9R is the right choice when searching for the simplest to use load following air/fuel ratio control system. The system is designed to maximize the efficiency of a three-way catalyst by maintaining the proper air/fuel ratio over varying engine loads, speeds, fuel quality, ambient temperatures and barometric pressure. This is done without operator intervention after the initial program setup.

The AFR-9R features nine set point targets based on a combination of three RPM settings and three manifold pressure settings and includes three valve default position settings. As your engine’s load and/or speed change, the AFR-9R anticipates (feed-forward control) and corrects the air/fuel ratio to optimize catalyst performance.

The system includes the Murphy PV-450 full-color graphical user interface for control functions, monitoring, programming and diagnostic displays. The eight-button display includes comprehensive built-in help files for added operator convenience.

The Murphy AFR-9R air/fuel ratio controller represents cutting-edge technology in many areas: hardware, microprocessor power, control system software, operator interface options, adaptability to variable engine conditions and control requirements, software upgrade capability, in addition to comprehensive on-board diagnostics system (OBD).

 

Main Features

  •   Simplest load-following AFRC system available.

  •   Designed for a wide range of horsepower, gas-fueled carbureted rich-burn industrial engines.

  •   Designed to maximize the efficiency of a three-way catalyst over varying engine loads, speeds, fuel quality, ambient temperatures and barometric pressure.

  •   Works without operator intervention after initial program setup.

  •   Nine set point targets based on a combination of three RPM settings and three manifold pressure settings (3 x 3).
