Compliance Controls offers an advanced, cost-effective, flexible, easy-to-install and easy-to-use Air Fuel Ratio Control System for Rich Burn and Lean Burn engines.

MEC-R Rich-Burn Air-Fuel Control System

The MEC-R controls rich-burn, natural gas-fueled engines – maximizing 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 pressures.

Easy to install, even easier to use, and equipped with a comprehensive on-board diagnostics and troubleshooting system, the Windows-based MEC-R redefines the state-of-the-art – in hardware, microprocessor power, control system software, operator interface options, adaptability to variable engine conditions, and software upgradeability.

MEC-L Lean-Burn Air-Fuel Control System

The MEC-L Lean-Burn Air-Fuel Control System was engineered specifically for lean-burn, spark-ignited natural gas engines. It minimizes engine emissions, maximizes fuel efficiency, and cuts engine maintenance costs by maintaining the proper air-fuel ratio over varying engine loads, speeds, fuel quality, ambient temperatures and barometric pressures
