Rich Burn Air MEC-R1

MIRATECH’s MEC-R1 Rich Burn Air/Fuel Ratio Control system maximizes emissions-control efficiency by maintaining the proper air-fuel ratio for engines that operate at a fixed set point. The MEC-R1 provides operators with 1 setpoint to ensure compliance for steady state engine operation.

MIRATECH’s MEC-R1 controller uses a heated oxygen sensor mounted in the engine’s exhaust (upstream of the catalyst) to detect drift in the engine’s air/fuel ratio over time. As an engine drifts “Lean” there is less fuel to combine with oxygen during combustion leaving more “leftover” oxygen passing into the exhaust. An engine drifting “Rich” is the opposite. More fuel requires more oxygen to burn, leaving less pure oxygen passing into the exhaust.

As an additional option, the MEC-R1 offers the ability to run a post catalyst oxygen sensor. In many cases, a post catalyst oxygen sensor can enable the MEC-R1 to compensate for slight changes in the system over time.

Post catalyst control may be thought of as a separate controller unto itself. The post catalyst control loop compares the reading from the post catalyst sensor with the user set target and biases the pre catalyst target rich or lean depending upon the error.

The MIRATECH MEC-R1 is the right AFRC for a 3-way catalyst.
