S.N.G.E.C. Systems


MurCal's Stationary Natural Gas Emission Compliance Systems are exclusive emission compliance kits, customized for stationary natural gas fueled internal combustion engines, that include component parts, custom installation and certification by the San Joaquin Valley Air Pollution Control District.

The District issued MurCal a Final Certification under District Rule 4702 (Internal Combustion Engines) for our Stationary Natural Gas Emission Compliance (SNGEC) System.

Rule 4702 for natural gas-fueled, agricultural, rich-burn, spark-ignited IC engines requires a reduction of exhaust emission levels to less than or equal to all of the following limits, corrected to 15% exhaust oxygen content:   90 ppmvd-NOx,   2,000 ppmvd-CO,   and 250 ppmvd-VOC.

Engine operators with MurCal's SNGEC add-on emission control system will satisfy District Rule 4702 by installing the following required components:

•   FW Murphy Production Controls AFR-1R, AFR-9R, or AFR-64R air/fuel ratio controller,

•   Johnson-Matthew Model Modulex B or Modulex C, 3-way catalyst,

•   Zirconia HEGO type oxygen sensor(s),

•   Manifold Absolute Pressure (MAP) sensor, and

•   Two (2) Type K thermocouples


The SNGEC System described above is now considered to be "District Rule 4702 Certified" for any natural gas-fueled, rich-burn, agricultural IC engine for which it has been individually designed.
