FW Murphy - Model Rich-Burn-AFR-64R -Air/Fuel Ratio Control System
The AFR-64R air/ fuel ratio controller monitors ambient changes, reacts with precision and diagnoses potential problems before they become costly.
- Fast, easy, low-cost installation
- Fits virtually any gas-fueled, carbureted, rich-burn engine – with (or without) a catalytic converter
- Comprehensive 38-fault diagnostics, including continuous oxygen sensor health monitoring
- Data plotting for easy, accurate troubleshooting
- Variable set-point for pre-catalyst and post-catalyst exhaust oxygen control – for real-time response to varying engine loads
- Up to 64 load-specific air/fuel set points to map your engine
- Catalyst temperature monitoring for catalyst over temperature protection
A lot of control in a single package.
Emissions Compliance: The AFR-64R 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, engine valve issues and more – to cut the costs of maintenance, downtime, labor and replacement parts.
Whether you need better emissions compliance, engine prognosis/diagnosis or trouble-free equipment life, the AFR-64R helps maximize the efficiency of the engine and its three-way catalytic converter.
