EPC-50 air/fuel ratio controllers are on the market for low-horsepower, carbureted natural gas-fueled engines.
It employs microprocessor technology for high-level control, easy configuration, and diagnostics. This controller and associated small engine-specific control valves are designed for use on engines operating at or near a stoichiometric air/fuel ratio. They are especially suited for application with three-way catalytic converters.
Single control output allows for EPC-50’s use on any engine application incorporating a single fuel gas regulator. An oxygen sensor is used in the exhaust stream to sense O2 content. A thermocouple input signals when proper exhaust temperature has been reached to allow for accurate sensor operation. Full air/fuel ratio controller data are free.
