CleanFuel USA, a supplier of alternative fuel infrastructure and liquid propane engine systems, has announced a partnership with Capacity of Texas Inc. to develop and certify the country's first terminal trucks utilizing its cleaner-burning, liquid propane injection engine on a General Motors 8L platform.

The new line of Capacity propane-powered off-road trucks is targeted to meet the demand for alternative-fueled vehicles in port communities that are challenged to comply with stricter emissions rules. The tractors are expected to be ready in 2012.
