Compliance AFR-64L



compliance controls AFR-64L air fuel ratio controller

Advanced Lean-Burn, Load-Following Air/Fuel Ratio Control System

The AFR-64L air/fuel ratio controller provides state-of-the-art engine control in one simple, easy-to-use product.

Automatic Operation: No operator intervention needed – the AFR-64L controller automatically tracks multiple factors, including engine load, tailpipe emissions and more, then precisely adjusts the air/fuel mix to maximize fuel efficiency, minimize engine emissions, improve engine performance and reduce maintenance costs.

Emissions Compliance: The AFR-64L controller optimizes the lean-burn air/fuel mix to maintain targeted emissions levels over varying engine loads, speeds, fuel quality and ambient conditions.

Cost Savings: Pinpoint performance problems and avoid detonation. The AFR-64L controller’s advanced troubleshooting and diagnostics cover 76 critical operating parameters, allowing the operator to cut the costs of maintenance, labor, downtime and replacement parts.

Take control over your engine needs – engine diagnostics, emissions control, fully automatic operation – the AFR-64L does it all for you.
