American Power Group Inc. (APG) has signed an EPA test-vehicle-exemption agreement with Paper Transport Inc., a regional fleet operator headquartered in Green Bay, Wis., to launch an over-the-road test of APG's dual-fuel system.
The EPA exemption will allow APG to gather performance and emissions data on a pre-dual-fuel and post-dual-fuel basis to support recently announced EPA after-market approval requirements, the company says.
APG's dual-fuel system converts diesel engines and diesel generators to function more efficiently and at a lower operating cost by displacing 40% to 60% of the normal diesel fuel consumption with compressed natural gas, liquefied natural gas, well-head gas or bio-methane.
