Need a lot of control in a single package?

The AFR-64R air/fuel ratio controller monitors ambient changes, reacts with precision and diagnoses potential problems before they become costly.

Emissions Compliance:

The AFR-64R controller precisely tracks the air/fuel mix to maintain targeted emissions levels - regardless of variance in load, ambient air temperature or fuel composition.

Flexibility:

The AFR-64R controller stores up to 64 load-specific air/fuel set points and automatically tracks engine load changes based on engine rpm and manifold air pressure.

Cost Savings:

Pinpoint performance problems as soon as they occur - misfires, detonations and more - to cut the costs of maintenance, downtime, labor and replacement parts.

Whether you need better emissions compliance, engine prognosis/diagnosis and trouble-free equipment life, the AFR-64R air/fuel ratio controller helps maximize the efficiency of the engine and its three-way catalytic converter.


Main Features

• Multi-set point (64), load tracking, air/fuel ratio controller
• Pre- and post-catalyst engine exhaust monitoring
• Critical engine and catalyst function diagnostics
• Continuous health monitoring of the oxygen sensors
• Tracking includes engine load, tailpipe emissions, ambient air temperature, fuel composition and more


Benefits

• Ongoing emissions compliance
• Elimination of operator guesswork
• Reduced maintenance costs
• Ability to identify problems early and save on repairs
• Minimal operator intervention and training


Technical Features

• Fast, easy, low-cost installation.
• Fits virtually any gas-fueled, carbureted, rich-burn industrial engine - with (or without) a catalytic converter.
• Windows-based platform compatible with most computers.
• Software can be installed on laptop, PC or network.
• Comprehensive 38-fault diagnostics, including continuous oxygen sensor health monitoring.
• Data plotting for easy, accurate troubleshooting.
• Separate alarm and shutdown dry-contact relays.
• Pre-catalyst closed loop, exhaust oxygen feedback control.
• Post-catalyst exhaust oxygen feedback; cascade control for fast, real-time adaptation to changing catalyst performance.
• Variable set-point for pre-catalyst and post-catalyst exhaust oxygen control - for real-time response to varying engine loads.
• Catalyst temperature monitoring for catalyst over temperature protection.
• Drives up to two control banks for operation on "V" type engine configurations.
• Multiple valve control options:
  - Full Authority Valve controls all engine fuel via system-controlled butterfly valve
  - Trim Fuel Valve adds supplemental fuel to the air intake via system-controlled proportional fuel valve
• Display - Viewable monitor (optional).
• RS-485/MODBUS communications support for high-speed data transmission.
