EcoDual has received authorization from the U.S. Environmental Protection Agency (EPA) to start installing its dual-fuel conversion system on 29 engine families of the 2004 to 2009 Cummins ISM engines.

The EcoDual conversion kit for the Cummins ISM 11L engine allows fleets running heavy-duty diesel engines to substitute natural gas, EcoDual said. According to the company, 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 Scott Myers, CEO & president. “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-mi. warranty and lease-to-own financing for immediate fuel savings.”

EcoDual said it hopes to release conversion kits for a number of engines over the next 12 months, including Cummins ISX and engines from Detroit, Mack, Paccar and Caterpillar.
