EcoDual achieves EPA compliance for natural gas conversions of heavy-duty diesel engines under CAFC rule
EcoDual, LLC, a provider of dual fuel natural gas conversion systems for heavy-duty diesel trucks, has achieved US Environmental Protection Agency (EPA) compliance for installing its systems on 2004 to 2009 Cummins ISX engines.
The EcoDual technology enables existing diesel engines to be converted to operate on up to 85% natural gas, providing fuel cost savings and emission reductions. The cost of the dual fuel system can be recovered in operational savings within one year without any government incentives, the company says.
In 2011, the EPA streamlined the regulations for natural gas engines to support small businesses providing their technology in the rapidly growing natural gas vehicle market for heavy trucks. This “Clean Alternative Fuel Vehicle and Engine Conversions” (CAFC) rule, created a special category, known as Outside Useful Life (OUL), which applies to heavy-duty diesel engines with more than 435,000 miles, or more than 22,000 hours of operation, or are more than 10 years old. The EcoDual system achieved its EPA compliance under this rule.
The EcoDual conversion system was successfully demonstrated and tested on cross-country runs in a truck provided by J.W. Stenger Trucking of Barnesville, OH. Over the next 12 months, EcoDual will be releasing multiple systems certified for newer trucks with the Cummins ISX and other engine families from Detroit Diesel, Mack and Caterpillar.
In dual fuel operation, the trucks maintain full torque and power with no loss of miles per gallon. The systems are easily installed at the fleet owner’s site and are fully warranted. Dual fuel provides the added benefit of automatic operation of the truck on 100% diesel if the natural gas tank runs dry.
