GreenMan Technologies Inc. announced that its American Power Group Inc. subsidiary has signed a U.S. Environmental Protection Agency Test Vehicle Exemption agreement with Paper Transport Inc. to launch an over-the-road test of APG’s dual fuel system. The EPA exemption will allow APG to gather critical performance and emissions data on a pre-dual fuel and post-dual fuel basis to support recently announced EPA aftermarket approval requirements.

Paper Transport Inc. is a regional fleet operator headquartered in Green Bay, Wis., with more than 280 power units delivering goods and services to customers in dedicated and regional configurations. Paper Transport Inc. has regional fleets in the Upper-Midwest, Southeast and the Central Plains, as well as intermodal drayage operations and a logistics offering.

Lyle Jensen, GreenMan’s president and chief executive officer, says EPA in April formally amended the alternative fuel aftermarket conversion regulations for light-, medium- and heavy-duty vehicles, which opens the market for properly engineered conversion systems to many diesel trucks on the road today. “The positive performance attributes of our APG V-3000 Dual Fuel System are well positioned to take advantage of this opportunity,” Jensen says.

APG’s dual fuel system is designed to displace 40 to 60 percent of the normal diesel fuel consumption with compressed natural gas, liquidfied natural gas, well-head gas or biomethane, with the flexibility to return to 100 percent diesel operation at any time. GreenMan says APG’s dual fuel conversion and emissions reduction systems can help users achieve their sustainability goals through lower carbon monoxide, nitrogen oxide, and particulate matter emissions, and that the introduction of natural gas through APG’s dual fuel system does not impact diesel engine power or pulling torque and will assist in extending the engine’s oil life, as natural gas is a clean-burning fuel.
