The Emissions Control System that Pays for Itself!
TermiNOx™converts any open-loop LPG or CNG fueled off-road engine into a state of the art, digitally programmable, closed-loop, 3-way controlled engine that simultaneously reduces CO, HC, and NOx emissions by an impressive and verified 85-90+%*. In addition, the fuel efficiency of the vehicle typically improves by as much as 20% - combine these savings and reduced building ventilation costs and the TermiNOx™ system can provide you a full return on investment in as little as one year.

TermiNOx upgrades uncontrolled spark ignited engines used in industrial applications with state-of-the-art, electronic closed-loop fuel control and 3-way catalytic emissions control to reduce:

Smog-causing (HC+NOx) emissions by >90%
Toxic Carbon Monoxide (CO) emissions by >85%
Fuel Consumption by 10-20%
Verified as the only LSI technology (large displacement engine spark ignited) by the Air Resources Board

Stone Equiptment also offers 2-Way Purimufflers for LPG, CNG and Gasoline industrial engines.
