Approval for 15-Liter Cummins Engines Built from 2007 to 2009

Columbia, S.C.-based Skygo Fuel Systems reports U.S. EPA approval of its natural gas-diesel dual fuel conversions for 2007 to 2009 Cummins ISX engines. According to data provided to the EPA, the Skygo aftermarket upgrade reduces emissions by up to 20%, with natural gas substitution for diesel approximately 60%.

“The system delivers a very compelling financial ROI, and just as importantly, a very impressive environmental ROI,” the company says. Skygo equipment is manufactured by Ambac International at an ISO9001-certified facility, also in Columbia, S.C.

Skygo claims the highest diesel displacement of any similar product, with 40% even at idle.

Skygo-logo“Engine power remains the same without degradation in power or performance,” the company says. “From the engine ECU’s point of view, it simply ‘sees’ the gas as a reduced load while the ECU continues to control the engine as it was designed to operate. Exhaust gas, coolant, oil and manifold air temperature levels all remain within normal limits. Emissions drop as gas substitution lowers the production of diesel byproducts.”

“You can’t tell it’s running on natural gas,” says Skygo president Michael Kilbourne. The vehicle drives exactly the same as it did before the truck was converted.”

12-Hour Installation

“The Skygo system intelligently substitutes natural gas for diesel with no loss of power or torque while in use,” he says.

Installation takes about 12 hours, and includes a 7-inch Droid tablet in the cab for engine information display and integration with telematics systems.

Based on the U.S. EPA nod, the Skygo system for the 15-liter Cummins ISX has been approved for funding in Texas. The company is applying for federal approval of its dual fuel system for the 12.7-liter Detroit Diesel Series 60 engine as well.
