Air/Fuel ratio control
You may be considering a costly conversion that may or may not achieve the results you expect. The most cost effective and proven method to meet Multi Sector Air Pollutants Regulations (MSAPR), is with a state-of-the-art air/fuel ratio control system (AFRC) and a non selective catalyst.
Just ask our neighbors to the south. With stringent EPA emissions regulations, the engine type of choice is rich burn equipped with a non selective catalyst. As well, modern factory lean burn engines will comply in most jurisdictions.
Continental Controls Corp manufactures the best air/fuel control technology available. OEM supplier to turbine manufacturers, Continental has applied the same technology to reciprocating engines. The Continental electronic gas valve has the quickest reaction time and will adjust in milliseconds to maintain a specific oxygen value in the exhaust stream thus ensuring stable engine performance. This technology will improve starting reliability, reduce cylinder head temperatures, improve fuel economy and eliminate nuisance shutdowns due to poor fuel control.
Simply put, an AFRC with stepper motor control doesn’t compare to the Continental Controls technology.
If you are considering an upgrade to your air/fuel ratio control, Optimotive has partnered with Vortex Production Services to supply and install a complete Continental Controls Corp AFRC system and Catalyst element / housing assembly for less than half of the cost of a rich to lean burn conversion.
