AFR-FI Air-Fuel Ratio Control For Lean-Burn Fuel Injected Natural Gas Engines

Simply the Best Value

Compliance Controls’ AFR-FI air/fuel ratio controller is your best value

for fuel injected, lean-burn natural gas engines. What do you get with

the microprocessor-based AFR-FI?

FUEL EFFICIENCY. No more traditional pneumatics. The AFR-FI is a

“smart system” that automatically optimizes the lean-burn air/fuel mix to

ensure top performance and fuel efficiency.

AUTOMATED COMPLIANCE. The AFR-FI maintains tight control of

the lean-burn air-fuel mix with computer speed and precision.

LOWER MAINTENANCE COSTS. The AFR-FI delivers optimized

engine operation and stays alert with 26 alarms and shutdowns – covering

fuel flow and fuel pressure, intake manifold temperature, exhaust temperature, air manifold pressure, overspeed and more.

Other AFRs for lean-burn, fuel-injected engines deliver a whole lot less.

But the AFR-FI – with easy installation, automatic operation, state-of-the-art

technology – is simply the best value you can find.
