CleanFuel USA, Freightliner partner on 8-liter propane engine

CleanFuel USA will build and certify a multi-purpose 8-liter General Motors propane engine in partnership with Freightliner Custom Chassis Corp., a subsidiary of Daimler Trucks North America. Featuring CleanFuel’s new 8-liter liquid propane injection system, the medium-duty engine will offer fleet managers a high-performance, propane-powered alternative. First versions of the engine chassis will be designed for use in urban delivery trucks and school buses. CleanFuel expects the engine to be available for 2012 vehicles.
