EcoDual LLC, a provider of dual fuel conversion systems for heavy-duty diesel trucks, has achieved authorization from the U.S. Environmental Protection Agency to begin installing its systems on all 29 engine families of the 2004 to 2009 Cummins ISM engines.


The EcoDual conversion kit for the Cummins ISM 11L engine will provide fleets with an opportunity to substitute low cost natural gas for expensive diesel fuel. EcoDual's natural gas-to-diesel fuel substitution rate is the highest among all available dual fuel conversion kits.

The cost of the dual fuel system is often recovered in operational savings within one year without any government incentives.

"EcoDual is committed to providing a major cost savings to truck fleet owners," said CEO and PresidentScott Myers. "This approval of our ISM system greatly expands our dual fuel product line to nearly 50 engine families that can run on CNG or LNG. As with all of our other products, EcoDual will provide a 2-year/250,000-mile warranty and lease-to-own financing for immediate fuel savings."

EcoDual LLC, is an independent provider of patent pending, dual fuel conversion systems enabling existing heavy-duty diesel trucks to operate on a combination of diesel and natural gas with an average substitution of 60% natural gas over typical driving conditions.

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 at full power if the natural gas tank runs dry.

Over the next 12 months, EcoDual will be releasing multiple systems certified for newer trucks with the Cummins ISM and ISX engines and other engine families from Detroit Diesel, Mack, Paccar and Caterpillar. More information on EcoDual products is available at the company website, ecodual.com.
